So that was about two years ago now. It happened like I said. They both got a lot closer to each other since then. They really enjoy spending time together. Jack and I's love life hasn't changed any. If anything, he's better in bed than ever. I started working some nights at the hospital across town. Sometimes we would be short staffed for the overnight shift so I'd often volunteer to work the extra hours, so sometimes I wasn't home as much as I'd like to be. But after doing that, I'd usually get an extended weekend, which was nice.

Even though that night was quite a life changing event, we really didn't touch on it much after that. We'd sort of tease each other about it and Riley would get it on it sometimes. I think she found she sort of liked being looked at that way by a man and he knew he loved her so it was nothing to feel weird about. I thought nothing of it really. I knew they were attracted to each other, but a lot of people are attracted to each other and nothing ever comes of it. I felt they both understood it was fantasy and nothing more than that would come of it.

Boy was I so fucking wrong.

It had been a long week for me and soon after cleaning up after dinner, I told Jack and Riley I was heading to bed. Riley got up and changed into a big comfy shirt and went back into the living room and laid on the floor with a pillow under her belly. Jack sat in his big reclining chair with his feet up. I went in and took a nice, hot shower. When I toweled off, I walked back past the living room doorway. Riley caught my eye as I walked past. I had to double back and get a better look. I peaked my head around the edge of the door frame. I could see Riley, still lying on her belly, but with her legs bent with feet in the air, subtly swaying her hips back and forth and looking back toward Jack. I couldn't see him, of course. I looked a little harder and noticed that beneath the bottom of her big, comfy shirt, Riley wasn't wearing any panties! My surprise when I could see her glistening little pussy under shirt caused me to move my hand to my mouth in reflex and she saw me there and immediately stopped moving and snapped her head back around to the TV and closed her thighs.

Did that kid have any idea what she was doing to poor Jack? She knows that his dick gets hard for dark skinned girls her age with tits and ass like hers. Hell. Any man without an oath of celibacy would have a raging hard on getting a straight on look at her plump little hairless cunt, wet from excitement of teasing, craving to be filled with hot, throbbing cock.

I walked in the room, startling Jack, who jumped and shifted to his side and covered his crotch with his arm, no doubt hiding the stiff bulge in his pants. It was no big deal. So she gets off on teasing him. He gets a hard on and probably jerks off or other times comes and fucks the living shit out of me. I have no problem with that. It's kind of exciting and makes me strangely happy to know that they both "enjoy" each other so much. She absolutely LOVED making his dick hard. Loved teasing him and giving him a show. She was his little exhibitionist. I gave Jack a kiss and a smile and looked back toward her and pointed and whispered in his ear.

"It's getting harder to resist, isn't it, babe?" and rubbed his hard cock through his pants.

I shuffled off to bed.

I rubbed out a quick one with my personal massager while thinking of a fantasy that started with her teasing him like that. In my fantasy, he pulls out his cock and starts stroking it. She climbs onto his lap and guides his cock into her tight little hairless cunt and rides him like a cowgirl, thrashing about as she cums all over his big hard dick, her juices pouring down his shaft and over his freshly shaved balls. Then she grabs her by the waist and begins slamming her down on his cock while his sweat begins to bead on his forehead. He grits his teeth and jams his raging staff deep into her womb as his cock erupts inside her, filling the girl with potent sperm. That's the thought that made me cum and cum hard. I soon drifted off to sleep.

It must have been 30 minutes later that I woke up with some heartburn. I got out of bed and made sure my panties weren't soaking wet from my cum earlier. They were a little wet, but fine enough to get to the kitchen and back. As I approached the doorway to the living room, I heard whispering. I was intrigued and quietly snuck up to the doorway. I didn't want to peak in and be noticed this time. It was Riley's whispers.

"Look at my titties, Daddy. You wanna fuck 'em, daddy? You wanna fuck my titties?" she whispered softly.

"Holy shit!!," I said silently.

"Squeeze 'em, daddy. Put your big hands on my titties, daddy. Ooooo that's nice, Daddy. Put your hands all over 'em daddy. Think about sliding your big hard dick between them daddy. How about I go get the KY from mom's medicine chest and I squirt it all over my titties and you can pull out your cock and you can fuck 'em, daddy?"

"Because you know it's not right, baby. Mom's upstairs. We can't."

"Oh daddy. I love playing with you when Mom is home. It's so exciting trying to not get caught. It makes my pussy sooooo wet, daddy."

Ever since Jack and I had gotten together, I had hoped that she would call him "Daddy" eventually. This wasn't exactly what I had in mind at the time.

What did he mean when he said they can't do it because I'm home? Would he do it if I wasn't? Has he done it when I wasn't?? Oh wow. What have these two been up to?

"I love grinding my pussy onto your hard dick, Daddy. It's gonna make me cum soon Daddy. Your hard dick is going to make me fucking cum so good, Daddy."

I just had to peak after she said that. Her shirt was off. She was completely nude. Jack still had his boxers on. There was Jack, both hands massaging Riley's big, plump tits. Squeezing them and spreading them and putting his face between them and kissing her chest all over and sucking and biting her little red nipples. Riley was grinding her crotch into his hard like the best stripper lap dance ever. Her pert little ass was moving out and in while she expertly grooved her hips on him.

"Oh Daddy! I'm gonna cum!! Oh Daddy I wish I could slip your hard cock inside me just this once and let me squeeze it hard with my pussy while Mom is here!!"

"Baby, no!" whispered Jack sternly.

"It would feel so good, daddy, to feel it slip inside my tight, wet, warm pussy and feel it expand and inside me and feel it shoot off!! Oh Daddy I'm fucking cumming!!!," Riley said in a loud whisper.

"Shhhhh, baby...cum baby cum. Daddy's about to cum too baby. Grind on it just like that, baby. Ahhhhh....ahhhh shit."

"Yes Daddy...cum for your little girl!! Let me just hold it, Daddy."

Jack quickly fished his hard cock out of his boxers. Riley wiped her hand over her pussy, scooping up her lubricating girl cum and quickly smeared it on her tits and lowered them over his cock and squeezed them hard on him. Jack was silent. He just watched, unable to do anything to stop the his impending eruption. Three, four, five times she slid her big tits down his shiny cock before he thrusted forward, threw his head back and grabbed her tight little waist.

"FFfffuuuuuuuck!!!!" he whispered softly.

Then it happened. Jack came like I've never seen the man cum before. His first bolt of thick, creamy sperm splashed audibly against her neck and began dripping down between her breasts as the second thick helping met with it and began a river of semen that began to pour down her tits. She looked down just as the third bolt flew even harder out of the tip of his enflamed cock and landed squarely on her bottom lip and began drooling down her chin. She eagerly licked at it with her cute little pink tongue. His cock continued to pulse and shutter as her father's sperm continued to lather her big beautiful breasts. She began rubbing the cum into her breasts and circled her nipples.

"Ahhhhh...oooohhhh fuck yessss. Baby. We can't be doing that stuff when Mom's here! What if she woke up and found us like this?"

"You mean what if Mom found me covered with your creamy cum and your big dick between my tits? I think she might cream herself."

The girl was a mind reader. Watching this all go on, I didn't even realize I was rubbing my pussy the whole time. I had cum and my thighs were covered with my juices. The floor was dribbled and slippery.

"Besides. It's not like you had your dick in my pussy or I was sucking you off or anything. You were just rubbing it on my tits and I ground on you. It's not so bad. Not THIS time."

Jack gave her a look and told her "You better get to the shower. The last thing your mom needs to see is a quart of dried cum on your chest first thing in the morning."

I quickly scurried back to bed. My heartburn no longer bothering me.
