Watching Trey


Part III


Chapter 1


Sunday night at the Morses this week was a nice roast.  As always, the aromas quickly had Robbie's mouth watering.

Before the three of them settled down at the table for dinner, Robbie was able to find a few minutes to speak quietly  -  privately  -  with Lindsey.  He asked if she'd had a chance to speak with Dr. Carey after Trey's doctor's appointment last Wednesday.  Lindsey said she'd been able to get the doctor on the phone on Thursday morning while she was still out of town.  She had been very surprised but pleased that Dr. Carey spent as much time as she did, going over her findings and answering all the questions that Lindsey had peppered her with.

"Did she tell you about the `S-E-X' thing?" Robbie asked.  

Lindsey was chuckling, "Dr Carey thought you were going to have a stroke when she told you that.  She thought your reaction was hysterically funny.  Or maybe that you were nearly hysterical.  Or something like that.  Anyway, she thought that after you guys talked a little more, she felt you were beginning to come to grips with what Trey's body is going through these days.   So, is she right?  Are you beginning to comprehend, to accept the fact that Trey is growing up?" 

 "Not very well," was his somewhat sullen reply.

Over dinner,  Lindsey and Trey told Robbie about Trey's upcoming birthday party and sleep-over.  

"I've told Trey she can have up to five of her girlfriends come over for her birthday party and sleepover," Lindsey explained to Robbie.  "The folks at work know that I plan to fly home early on Friday, so I should be here by 1:00 or so.  I've got everything pretty well planned, and we'll be able to pick up all the last minute stuff before the girls arrive at around 6:00."

"Good Lord," Robbie sympathized, "have you gone insane, woman?  Have you totally lost your mind?  It'll be a madhouse!"

"Of course it will!  But it'll be fun, won't it Trey?"

"Yes Yes Yes!  And I'll be 12 years old!   That's almost a teenager!" 

"You need me to do anything to help you get ready while you're out of town this week?  Is there anything I can help you with?"  Robbie offered.

"No, I don't think so, Robbie.  I think I've got everything under control.  But we're both hoping that you'll come to Trey's party."

"Oh YES.  YES, YES, Robbie!  Please come to my birthday party!"

"I wouldn't miss it for the world, Squirt!"

"Oh, I almost forgot,  I need to ask another big favor, Robbie.  One of the girls that's coming, Katryn Biese, Kat, is actually going to stay with us for a few more days after the party," Lindsey informed him.  "Her folks have to go over to Romania to settle her grandparent's estate, and they thought it would be a bit too much for Kat, so they asked if I would be willing to look after her for a couple of weeks while they're gone."

"I told Mr. and Mrs. Biese that you take care of Trey for me 2 nights a week while I'm out of town.  I wanted to make sure they knew about our arrangement and see if they would have any problems with it.  They said they `know all about Mr. Robbie.'  It seems Trey can't stop raving to her friends about how much fun she has with you!  Anyway, they said `Mrs. Morse, if you trust him with your precious Trey, then he should be fine with Kat, too!'  Now there I go again, Robbie!  I presume too much!  I shouldn't be committing for something like that without checking with you first.  I'm sorry"

"Lin, go ahead and presume!  You know it's fine with me.  We'll have a great time, won't we, Squirt?"

"Mm-hm, we sure will, Robbie!  Kat's my total best friend at school!.  She just turned 13 last week so she's an official teenager now!  She's in the class above me for most things, but we have a couple of activity periods together and I just love her!  She's beautiful, Robbie!  Just wait'll you meet her.  You're gonna LOVE her!"

"If you say so, Munchkin, I'm sure I will!


----    -----     -----     -----    

Trey had two more days of school before classes were officially over for summer vacation, so Robbie didn't see much of Lindsey or Trey until bright and early Wednesday morning, when Trey crashed into his house in her normal, `eye-of-the-tornado' fashion.

"Mom wants to know if she should drop me off at school, or if I can stay with you today, Robbie," she gasped out.  "Is it okay if I stay here?   Please?  Please, please, pretty please?"

Chuckling at seeing that the `high-energy Trey' was back, Robbie told her, "Of course you can, Squirt!  Go tell your Mom to get going, or pretty soon she'll end up being late and missing her flight."  

"'Kay, Robbie. Thanks! Back in a minute!"  And the whirlwind was gone again as quickly as she had appeared.

When she got back a few minutes later, Trey asked about what Robbie had planned.  "Well, as long as you're here, I'd really like to get some more pictures, Little One.  I've bought a lot more outfits that I'd like to try out with various settings.  Different lighting, other backdrops and stuff.  Will you model for me again, Trey?"

"Oh Yeah!  That was fun!  Can I ride the horsey again?"  

"Hmmmm, I don't know.  That wasn't exactly one of the set-ups I was thinking of for today."  Robbie looked over as Trey gave him her best set of `sad eyes', and couldn't help cracking a smile.  "Oh all right.  After lunch, you can ride the horse."   

"Yippee!"  

"You got me more clothes to try on, Robbie?" 

"Sure did, Munchkin.  A whole bunch of different things, top - to - bottom."  

"Is everything up in my room?"  

"No.  Since we're going to be using the living room as our `studio' again, I think it would make more sense if you used my study as your `dressing room'; it's much closer, and you won't be running up and down the stairs every five minutes.  Does that sound like a plan?"

"That's a good idea, Robbie.  Is everything already in there?"  

"Sure is.  Let me show you what I got."

Robbie and Trey walked into his study.  He popped open a big foot locker and started to remove various pieces, lining them up on one of the computer tables.  There were a half a dozen different skirts, as many different blouses, some shorts and halter tops, and more.  He was matching them up as he laid them out, deciding (with a little help from her) which blouse should go with which skirt, what kind of socks would go best with each outfit, and that kind of thing.

Finally, he opened up a large pink box containing a dozen new sets of panties, bras and camisoles.  Lovely little wisps of satin and lace, various pastels, one set in sweetheart red, some in smoky black and several different styles in virginal, innocent white.

"Robbie!   Oh my God, Robbie!  Oh My God, they're gorgeous!"

"I love how sweet but sexy you look when you're wearing sexy undies, Trey.  Even though nobody can see them, it's like YOU know you're wearing sexy underwear, and you just seem to radiate provocative sensuality!"

Her eyes were wide as she looked at him.  "I don't know what it means, what you just said, but I know I love these panties!"  She opened a package of pale pink panties and held them up in front of her.  "Oooh.  Uh-oh, Robbie, they're so pretty, but there's not very much to them, is there?  I don't know if I should wear these."

He had been careful the first time he had bought new underwear for her a couple of weeks ago to make sure that the panties were not too daringly cut.  He wanted to avoid scaring her, since all she'd ever worn were full cut, heavy cotton ones.  He knew the sheer satin fabrics would be enough of a shock, and he didn't want to overdo it all at once.

This time though, he had been much bolder.  Though there were no thongs in this collection, these were all high cut, or low riding or both.  And none of them had an excess of fabric front or back.  They would cut up across the cheeks of her molded butt, but they wouldn't cover it completely.  The fronts were also much skimpier than she was used to, narrowing to no more than a half inch or so wide by the time they came down to disappear between her legs.  And he again had spent considerable time in carefully removing the reinforced crotch material in each pair!

"Trey, Sweetheart.  Your birthday is in two days.  You're going to be twelve years old, almost a teenager, remember?  I thought it would be nice if you had some `teenager' underthings.  I think you'll find out that you will really like the way they feel;  the way they make you feel.  Can we try them for our pictures with all the new outfits today?"

"Well, okay, Robbie.  If you think it'll be all right.  And besides, nobody will see them under my clothes anyway, will they?"  

"That's right, Munchkin.  Since you've already opened the pink pair, what should we wear them with?"  They decided on a crisp pink and white striped button down linen blouse, with a fun little, flouncy skirt in a darker pink, almost red color.  Robbie asked her to just wear the matching pale pink lace bra and not to wear the camisole top for this first set of pictures, then left her to change in private.  "Just come on out to the `studio' when you're ready, okay?" 

 Trey looked like a dream when she came out dressed in the first outfit.  Today, Robbie had her doing a number of poses and started issuing directions more and more rapidly.  Trey found herself quickly becoming immersed in their project, easily getting used to following his instructions without even thinking about them.  

Robbie had her moving all around, bending, leaning, stretching, unbuttoning the top button of her blouse, shifting her weight from one foot to another, hand on cocked hip and looking at him from over her shoulder.  Robbie too was moving all around, taking shots from in front, from the sides, from the back.  Shooting up from the floor and looking down at her while standing on a step stool.

The pace of Robbie's instructions was now rapid-fire.  He had turned on a CD that was playing mostly percussion, with a steady, driving beat and he had Trey moving to the music.  She didn't even give it a second thought as he directed her to open another button, cock her hip while reaching down and grabbing a handful of the side of her skirt and raising it up to hold it at her waist.  Staring at him as he shot from her side, her face wearing an unknowingly sultry look that perfectly complemented the other elements of the pose.

From his angle at her side, Robbie was able to capture the spreading gap in her blouse, the satin and lace of the pink bra peeking out, as well as the entire length of her slim coltish leg, the waistband of her panties displayed at her jutting hip as Trey's hand had gathered the side of her skirt to her waist.

"Time for a wardrobe change, Little One," Robbie instructed.  "Let's go with the eggshell white ensemble for the next set.  Go ahead in and change, and I'm going to move some things around out here.  Okay?"  Trey didn't even hesitate, heading off to the study to change while Robbie brought out some other props, including a futon and a backdrop that gave the appearance of a young girl's bedroom.  He was just finishing up with scattering various stuffed animals when Trey came out wearing the new, cashmere-soft looking knit dress with a v-neck that opened down to just below the center of her chest.  The cups of the scanty bra that was part of the eggshell white set of underwear were held together by a front clasp that was just hidden by the base of the v-neck opening of her dress. 

He changed the music to a mellower sound and told Trey that he wanted her to appear as if she was daydreaming, smoothly moving through another variety of poses as if dancing with an imaginary lover (a bit of a stretch considering Trey's complete lack of experience) but Robbie guided her through the images he wanted. He had her begin to lightly stroke her hands down from her shoulders to her waist and then to simply continue with those gentle caresses while gliding around room.  Now sitting in a plush overstuffed but child sized easy chair, Trey was instructed to continue with the actions of smoothing her hands all around her body while shifting around in the chair.  

The pitch of Robbie's voice had changed; his directions were now coming out in a throatier tone while he started almost whispering to Trey to start imagining that there was an audience watching her.  Men.  Lots of men, wanting to see ... to catch a peek up under the hem of her skirt.  He noticed the beginnings of a blush appearing on her cheeks, a subtle change to the tempo as she continued to shift around in the chair, her hands maintaining the smooth caresses.  

"That's it, Trey, now lean back.  Good.  Stretch out.  Great!  Roll over to your side.  Good. Good!  Stretch out one leg.  Excellent, You're doing great.  Now roll right out and down onto the futon.  That's good.  Keep it going, keep it going!"  Robbie's directions were again coming at a rapid fire pace but he was now nearly whispering, urging increasingly suggestive, provocative poses as he continued to circle about with his cameras.

She was stretched out on the pad, arms extended above her head. "Okay, Trey, now I want you to start shifting around as if you're trying to get comfortable.  That's good.  Bring your hands down.  Good, slide them along the sides of your face.  That's good.  Keep fidgeting.  Wiggle your hips, back and forth.  Good.  Very good.  Keep your foot down and raise your left knee.  Good.  That's it.  Bring your hands down a little further. Good.  Let them settle right on your tummy.  Excellent Trey.

Continuing to wiggle, with her knee up in the air, the hem of Trey's soft eggshell white skirt was slowly beginning to slide down.  "Trey, left knee back down.  Keep squirming back and forth.  Good.  Good.  Slowly slide your hands up.  Slowly, Trey.  That's good.  Slide them up.  Up.  Across your chest.  Good, Trey.  Right knee slowly up, Trey.  Good.  Hips back and forth.  Good.  Very Good.  Hands sliding down.  Slowly, Trey.  Slide them down over your chest and down.  Good, keep going."

"That's good, Trey.  I want you to softly slide just the tips of your fingers down almost to the bottom of your tummy now.  That's right.  Now back and forth, Trey.  That's it, right across your belly button,  Good.  Hips wiggling back and forth, Trey.  Now, sliding back up.  Slowly back up.  Good.  Good.  A little wiggle.  Great.  That's good, Trey.  Knee back down.  Gently sliding your hands back and forth across your chest now.  Good.  Both knees up.  Excellent.  Keep them together but swing them just a little back and forth.  Good."

Unaware that the entire front of the skirt of the soft cashmere dress had now slipped off of her legs, pooling up at her hips, Trey was starting to `zone out', just listening to Robbie's directions and blithely carrying out his instructions.  "Hands slowly down.  Back and forth across your tummy.  Good.  Very good, Trey.  Bring them further down.  That's right.  Down a little lower.  Good.  Fingertips now pressing in down at the bottom of your belly.  Knees opening.  Back and forth.  Good, Trey.  Keep rubbing down there, Trey."

Robbie now had an open view of the entire front panel of Trey's panties and even the area between her legs as she spread her knees.  These panties were white, satin and lace of course, but this pair had a see-thru mesh panel in the front that ran all the way down between her legs.  The view through the camera lens caused him to pause, just momentarily in his running commentary of directions to Trey.  His breath catching at the agonizingly beautiful sight of Trey's vulva, her perfect split peach so clearly on display before him underneath the mesh front of her panties.  

He had to mentally kick-start himself back into the job at hand, the slow, steady incitement.  This morning he had hoped to find out if he could get Trey to unknowingly stimulate and arouse herself to the point of passion, to see if he could guide her along to a point where nothing but those primal instincts were once again directing her actions.  

"Good, Trey.  Slide just one hand a little further down, closer to the top of your legs while the other hand slides back up over your tummy.  That's good, Trey.  Very good. Right hand sliding further up, Trey.  Up and over the right side of your chest, Trey.  Good.  Left hand pressing down right at the top of your legs, Trey.  Good. Lift that hand up and stretch it out to the top of your left knee.  Good.  Excellent, Trey.  Rub your knee, Trey.  Good.  Now let that hand slowly slide down your leg towards your tummy.  Slowly.  Close your right hand around the right side of your chest, Trey.  Good.  Gently squeeze now, Trey.  That's right.  Again.  Can you slide your left hand kind of between your legs and up towards the very lowest part of your belly?  That's it.  And back down now, Trey. Back up.  And down.  Squeeze your chest.  Excellent.  Again.  Good.  Slide that hand over to the other side.  Good.  And squeeze.  Good.  Again.  That's great, Trey."

Laboring to keep his voice from quivering, Robbie maintained a steady drumbeat of directions.  "Press in with your fingertips right there at the top of your legs, Trey.  That's right, Press in again.  Good.  Now just slide your fingertips down a little bit.  That's right, just a little ways down between your legs.  That's perfect, Sweetheart.  Now back up again.  Good.  Press in.  Slide down.  Down.  Back up. Start to move your right hand back and forth. From one side of your chest to the other.  Good.  Slowly.  That's good, Trey.  Squeeze.  Good.  Squeeze.  Good.  Press your fingers in at the top of your legs.  Great.  You're doing great, Trey!"

"Open and close your knees.  Back and forth.  Slowly.  That's good. Now, I want you to just keep repeating all those actions, Trey.  Left hand fingers, press in at the top of your legs.  Press in again.  Good.  Now slide those fingers down between your legs.  Rub up and down once.  Good.  Slide them back up.  Right hand squeezing on the right side.  Again.  Now slide over to the left side.  Good.  Excellent, Trey.  I need you to keep doing everything while I move around and shoot pictures from all different angles, all right, Sweetheart?  You just keep repeating everything.  Excellent, Trey!"

And she did.  Trancelike.  Robbie's droning voice hardly registering, Trey was now operating on a kind of autopilot.  Softly squeezing from one breast to the other.  Pressing in with fingertips at the top of her pubis.  Sliding her fingertips down along the entire length of her quim, rubbing into the crease. 

Her agitation was clearly building.  Robbie noted the moisture as it began to appear on the mesh panel of the panties.  The split down the middle of the pudenda widening.  Knees now swinging widely open and back together.  Trey's hips were starting to push up in counterpoint to the pressure from her fingers.  Rob looked up to see if the telltale flush had appeared on her chest and discovered that Trey's right hand had now found its way into the v-neck top of the dress, her fingers squeezing and rubbing her bra covered breasts, the soft fabric of the dress pulled out of shape to allow access.

Knowing Trey was now operating on her own, Robbie no longer spoke, becoming instead a silent witness to Trey's growing passion, probably her first ever experience in self pleasure. Her entire body was now involved, thrashing.  Head thrown back.  Eyes shut.  Mouth open.  Puffing and beginning a series of rhythmic grunts corresponding to the thrusting of her fingers along her now sodden gash.  

Her left hand slid up in preparation to make another run against her nether lips, the tips of her fingers finding their way under the waistband, her entire hand now sliding into the panties.  Her pelvis jerking in spasms as her fingertips slid into the groove, lips spreading wetly apart as the pads of her fingertips examined the furrow. 

She had somehow managed to unclip her bra, and the fingers of her right hand were now pinching and pulling, hard, on the nipple of her left breast.  Moaning louder now in time with the thrusting of her left hand along the groove of her pussy, the pinching / pulling of her nipple.  "Ungh.  Ungh.  Ungh." 

Suddenly, she froze.  Pelvis raised, fingers poised, barely .... barely .....  yes, the tip of her finger had found the bud of her clit.  Hips crashing down only to rise again, pubis jutting up.  "UNNgh. UNNgh. UNNgh."  Fingers now sloshing, digging deeper into the crease. "UNNGGhh.  UUNNGGhh.  UUNNGGhh."  Rocking.  Thrusting.  Humping.  Gasping.   Tightening.  Rigid.  Frozen.  "UUUNNNGGGGHHHHH!!!"

Trey remained frozen in that bowed position, mouth open in a now silent scream for more than a minute before the tremors started in her thighs and she shakily lowered her butt back down onto the padded futon. 

Robbie was glad that Trey had once again slipped into a stupor as her orgasm subsided.  She wouldn't know that he had come in his pants without even touching himself.  


Chapter 2

While she was still `out of it', Robbie took a few minutes to straighten Trey's appearance, pulling her left hand out of the panties (taking a moment to bring her fingers to his nose, inhaling deeply before carefully licking each one), lowering and straightening her legs, smoothing her skirt down,  pulling her right hand out of the top of her dress, and otherwise just leaving her in an innocent restful pose.  He went into the kitchen to prepare them something to eat for lunch and waited for her to return to the land of the living. 

Robbie had just finished placing a dill pickle spear on the side of each sandwich plate when Trey entered the kitchen, still looking a bit groggy, flushed with that certain look, but otherwise none the worse for wear.  Her eyes lit up at the neat sandwiches he had prepared.  "Have a seat, Munchkin.  Milk or Lemonade?" 

"Milk please, Robbie. Thank you."

 Placing both drinks on the table, Robbie sat down to join her for lunch.  "You did a great job this morning, Little One.  We got a lot of great pictures.  I guess I must have worked you too hard, though.  You ended up falling asleep on me there at the end."

"I did?  I don't remember."  Trey stared off with  far away look.   "I just remember moving all around and doing all the poses you were telling me to get into.  I guess maybe I was kind of tired.  I think I just kind of zoned out for a while."  Robbie wasn't sure if Trey didn't remember getting herself aroused to the point of orgasm, or if she remembered it and simply hoped he didn't notice.  

Even though they'd now shared a number of exceptionally erotic experiences, each resulting in mind-numbing climaxes for her (and occasionally, for him as well) Robbie suspected that Trey was completely unaware of how all-consuming her orgasms were .....   (he thought that it would be obvious to anyone within miles that a girl was having a very big climax here )  ....  he thought it was possible that as Trey's sexual arousal grew to a peak, she really wasn't conscious of anything else in the world around her. She became deaf, dumb and blind to anything but the urgent, burning pursuit of her orgasm.

"So what would you like to do this afternoon, Munchkin?"  

"You said I could ride the horsy after lunch!" was Treys immediate reply.  

" I guess I did, didn't I?  Well, I want to get at least a few more pictures of you, in some different outfits, so maybe we can kill two birds with one stone.  When you're finished, I'll show you what I want you to wear for this shoot, and you can freshen up and change while I get things set up in the studio."

In just a few more minutes, Trey and Robbie went into the study where he quickly located the day's final outfit.

"Uh, Robbie?"  

 "Yes, Munchkin?"   

"What's this?" 

"It's pajamas, what does it look like?"  

"Doesn't look like any pajamas I've ever seen!"  

"No?  I'll bet your mom has some like this."  

"If she does, I've never seen her wear them!"  

"No, you probably haven't, come to think of it.  These are big girl pajamas, kind of like the grown up, teenager kind of underwear you tried on this morning.  Big girls wear this kind of pajamas when they want to feel sexy and hot, or when they want to make a guy get all hot and bothered."  

At that, Trey's eyes got wide and round and that familiar blush rode on her cheeks.  "I don't know, Robbie."

"Look, Munchkin, all we're doing is modeling, so I can take pictures, so I can look at the prettiest girl in the world instead of having to look at those other girls on the computer when you're not around.  You saw, a lot of those girls have their pictures taken in nothing but their underwear!  I haven't asked you to do that, although I kinda wouldn't mind having some like that."  He sort of whispered that last part, hoping she'd be both intrigued and  flattered by his open admission.  He was right.

"Oh, you, Robbie.  Okay.  I may need you to help me figure out how to put it on."

"It's really not much different from your other camisole and panty sets, Sweetheart.  It's a `babydoll' top, which means it's only supposed to come down to a little below your hips.  And then there are these matching panties for the bottom."   

As with nearly everything he'd purchased for Trey to wear, these PJs also were extremely sheer.  Virtually transparent, with the merest hint of red to the shimmery fabric.  Stripes of a heavier silk fabric were woven into the gossamer fabric.  On the top, The darker silk accents seemed to highlight the swelling of her breast, while the wispy panties had the silken bands around the leg holes as well as one that ran right down the middle, from front to back.  

Once again, Robbie couldn't help but catch his breath when Trey came into the `studio' wearing the new pajamas.  The fabric of the top seemed to just float about her torso.  Her swelling young breasts were totally visible through the sheer material, allowing him to again marvel at the firm mounds, puffy areola and dark, prominent nipples.  The panties too, did not leave much to the imagination, although that stripe of silk ribbon did appear placed to discretely conceal her crease. 

Robbie had again set his very special, oversized hobby horse in the middle of the floor in their `studio' space, and now checked, "Ready for a horsy ride, Munchkin?"

"Oh yes, Robbie.  I sure am!  I still can't believe how beautiful he is.  Have you had him very long?"

"I put it together as a special project a while ago, and I only bring him out for very special people.  Go ahead and climb on, Sweetheart.  See if he puts you to sleep like the last time."

Trey climbed onto the rocking horse and settled herself into its very carefully carved saddle.  Robbie was pleased with the overall effect of his costume selection for this `modeling' session.  Not only was the top of the baby doll pajama outfit nice and short, but since both pieces were virtually transparent, his views of all of the upcoming action should be completely unimpeded, unlike with the skirt and blouse she had been wearing for her first ride.

Sitting quietly for just a few seconds as the springs slowly settled, Trey placed her feet onto the wooden pegs that extended out from the horse's front legs and slowly straightened her legs to push herself up to the back of the steeply sloped saddle.  Rocking springs now caused her to slip down the  highly polished seat, blissfully unaware that the ridge that ran along the center of the saddle, almost imperceptible near the rear of the saddle but becoming more pronounced the closer it got to the pommel was but one of several features that Robbie had designed into his customized rocker. 

Trey took her time this afternoon, only gradually working up to a faster pace, straightening her legs to push herself up to the back of the saddle, then letting herself slide down.  She didn't immediately allow herself to slide all the way down and against the pommel; she just slid back and forth on the smooth saddle, unaware that the special ridge was slowly but surely wedging open the outermost portals of her gateway.

She finally slid the entire length of the ridge, for the first time today, her vulva ending up pressed up against the pommel.  Robbie had already activated the concealed vibrating unit to its lowest setting and, as Trey stopped at the end of her slide, her breath caught as she felt the slightest tingle `down there', causing her to sit straighter for a moment and kind of shiver, before sliding back several inches to end the contact.

Impressed by the level of restraint Trey was exhibiting in maintaining such a slow, deliberate pace in her ride this afternoon, Robbie observed closely, noting her brow furrowed in concentration in an apparent effort to wring out every second of sensory pleasure.  Slowly pressing herself to the back of the saddle.  An agonizingly slow slide along the ridge, only the slightest of wiggling on the seat as she made her way down to finally press once again against the pommel.  Pausing there for just a few quivering seconds.  Again.  Again.  Pace slowly building.  Rocking springs quickening.

Moving around to capture the action , Robbie was now able to discern the beginnings of a slick of moisture appearing along the top of the ridge.  Trey was pressing more firmly against the pommel on the bottom of each slide.  Using his little remote, Robbie set the vibrating element to the next higher speed. 

Fifteen, no eighteen minutes now into her ride, Trey was now using full leg extension to firmly push herself all the way back to the raised rear of the saddle, sliding more quickly down along the ridge and now allowing herself to literally bang up against the pommel, freezing for a few seconds at the end of each slide.

Robbie saw the front of the sheer panties now stained darkly with the fluids flowing from Trey's pussy.  Each time she came down against the pommel now it appeared to be embedding itself further into her furrow.  As she pushed back, Robbie could see the panties remaining lodged, wedged into her crease.  After the next slide down, as she  pushed herself back, Robbie finally saw what he'd been waiting for.  The satin ribbon running down the center of this special pair of panties was actually a carefully designed closure.  The satin ribbon was in fact similar to Velcro but of a much more sophisticated design and as intended, it was now beginning to spread open.

Trey's ride was building speed.  She was thrusting harder with each contact with the pommel.  The panty crotch now spread wide open, Robbie could clearly see the tendons in her thighs straining to spread herself wider, to accommodate more of the protrusion.  

Trey was no longer pushing as far back.  She was only taking short strokes, her energies consumed in humping down against the pommel, now writhing on top of it in a frenzied effort to bury it within herself, it's vibrations now sending shuddering pulsations directly onto the bud of her clit.  Now all she was doing was using her legs to raise her pelvis straight up and down, adding a front to back motion, desperate to envelope the thing.  Down.  Harder.  Again.  Agai   ....    wait    ....   wait     It's ther ... I think it's  ... Oh GODD it's innnn.  Oh god.  It's good.  Oh god oh god  oh god oh my GODDDDD.   

Robbie's remote controlled some other functions in this marvelous device, and he now activated them all, increasing the vibrations by another notch as well as starting the pulsing and extending actions.  Careening headlong into full-out sexual frenzy, Trey was now simply screeching.  Trying to form words and failing, she was bucking as if impaled on the back of a raging bull.  Bending at the waist, she threw her arms around the neck of the horse while her pelvis writhed out of control.  Screaming.  Gasping. Straining arms hanging on. Straining legs,  thighs pumping, hips thrusting up and down. A final gasping howl.  She passed out.

Robbie used his remote control to shut everything down, while watching as Trey's unconscious body continued to quiver.  Minutes later, all tremors had finally passed, so Robbie gently gathered her up in his strong arms, being extremely careful as he lifted her off the device that had provided her such mind-bending pleasure.
