My sister, Barb (who has her story in your Library at 3-022-BARB), asked me to drag out my old diary and use it to tell you about how I got started being the extra gal with select couples who want to enjoy three-way sex.  So... here goes.  It all started about three years ago when I briefly moved in with my sis and her husband.


Barb and I have always been very close, even though she is four years older than me.  She got married to Harv (a handsome hunk of a guy) at age 20, shortly after I turned 16.  Prior to that she had always talked with me about the boys she dated, and the sex play things they did.  When she met Harv, she stopped dating other guys, but she told me all the fun she and Harv had in bed (and in his car). 

Naturally, when I started dating, I took advantage of what I had learned through my sister.  I began enjoying sexual experimentation at a fairly early age.  At first it was mostly heavy petting and oral sex.  By the time I was 17 I was on birth control pills, and decided it was time to 'loose my cherry.'  I quickly found that I really enjoyed sex.

Barb, my sis, and I continued to share information about our sexual exploits, even after she was married   She told me about many of the things she and Harv did together, and I told her about the experiences I had with various boys.  When I was 19, I decided to move to the city where my sis and Harv lived, to continue college.  She invited me to stay with them until I got settled.  That's when I learned more about my sis's sexual adventures.

Upon my arrival, Barb met me at the airport.  Harv was still at work.  After we got into the car and headed for their apartment, Barb giggled and told me she had some new things to share with me, but to wait until we got home.

At their place we changed into our sweats, and ended up on her bed to talk.  Barb switched on the combination TV/VCR that was in their bedroom.  "I want to show you something special," she announced.

The picture came on.  At first I thought it was just a conventional porn flick she had rented.  I had already seen a number of such videos.  However, I was really surprised when I recognized my sis as the woman who was being enthusiastically screwed in the scene before me.  Barb watched my face as the camera panned back and I could see that the guy was NOT Harv!

"My Gawd," I said.  "Who is that... and where is Harv?  Does he know about this?"

Barb giggled some more as we watched the guy pumping in and out of her image on the TV.  "That's Martin," she said. "He's a new friend of ours.  Sure Harv knows.  Who do you think is holding the camera?"

"You mean he doesn't mind if you have sex with another guy?" I asked, unable to quite grasp the situation.

"Truth is," Barb answered, "Harv set up that special session... as a 'gift' to me.  He tells me he loves to watch me get screwed by other guys... and to hold me in his arms while I am enjoying some strange stuff."

"Other GUYS?" I asked.  You mean you have screwed more than one guy with Harv's permission?"

That's when Barb flicked off the TV and began telling me about how she and Harv had launched into a new phase of their married life during the past year.  "I didn't want to tell you until I could do so in person," she said.  She told me that one weekend they visited an adult motel where swingers regularly meet and 'party.'  She said they tried some 'swinging,' but found that they most preferred threesomes where Harv would invite another guy to join him in "enhancing" my sister's pleasure.

All I could do was listen intently and repeatedly say "WOW" as she told me about their various threesomes.  She told me she had already had five different guys through Harv's planning.  I was mesmerized by all that Barb was telling me... and I was getting really turned-on.

Then came the big surprice.  "Carrie," she said, "I thnk it is about time that I set up a two-gal threesome for Harv... to thank him.  And, I think you would be the ideal extra gal!"

Now I had always found Harv to be an extremely sexy guy, but since he was my sister's husband, I had never even thought about seducing him or thought about the possibility of going to bed with him... so Barb's suggestion was a bit of a shocker to me.  Then, the more I thought about it... and thinking about the stories Barb told me about her enjoyment of extra guys... I began to seriously entertain the idea.

My sis asked if I was still on the pill.  I assurred her that I was.  She then gave me a hug and assurred me that she had given her idea a lot of thought, and truly wanted her husband to have sex with me... particularly since he had made it possible for her to have sex with several other guys.  She convinced me that she would not be jealous, knowing (and watching) that Harv was having sex with me.

Barb told me that the next day (a Friday) would be Harv's birthday.  She proposed that we give Harv a very special surprise birthday gift.  Her plan was that upon his return from work the next day she would tell him to take a shower and get ready so we could give him a special birthday dinner.  The "dinner" was to be finger food that we would feed to him... in bed... with all of us naked.  But she did not plan to tell him those details of her plan.

I gulped, asked if she was serious.  When she assured me that she was,  I said, "Let's do it!"

That night Harv came home to find Barb and me dressed in short shorts and our lowest-cut blouses.  He looked at me and said, "Boy have you grown up to be a sexy woman."  I just blushed, gave him a kiss and an extended hug... and we all sat down for a conventional dinner.

That evening Barb and I put on our baby doll PJs and the three of us lounged around the TV for the rest of the night before heading for our beds.  I caught Harv checking out my loosly covered breasts.  I guess my anticipation of the following night had caused my nipples to harden, and caused a bump in my top.  Nothing sexual happened that night.  We were all on our best behaviour.

Oh yeah.  I guess I should describe myself.  As I said, at that point I was 19 (now 22), and I had developed a fairly attractive body.  I weighed 119 lbs (still am in the 120-125 range), measure about 36,24,35, and have C-cup titties that tend to be firmly pear-shaped, with rather large nipples.  I keep my dark brown hair (with natural red tones in it) trimmed short (easier to work with... particularly with my active life in sports).

Friday morning, after Harv left for work, Barb told me she and he had enjoyed a great screw together after hitting their bed the night before, and that she told him that she noticed him studying my body.  He had admitted that he found my grown-up body to be "quite appealing."  That left me feeling more comfortable with what that evening might bring.

During the day Barb showed me videos of a couple of her other encounters with different guys... one a young black guy (Gawd that was hot), and one where she was being eaten by a well-hung older guy.  We made our plans for the evening.  That afternoon Barb boiled up some shrimp and cut up some fruit and cheese to use as finger foods.

When Harv arrived home that evening, Barb and I had freshly showered, dotted perfume in all the right places, and were wearing our baby dolls again.  We each gave him a big hug and kiss (I could feel his hard cock pressing against me as we hugged), and Barb said, "Harv, take a shower.  We have your birthday dinner ready."

After he got into the shower, Barb asked me to go into their bedroom and wait just outside the bathroom door so I would know exactly when Harv turned the shower off.  She had it all planned out.  I was to walk in, find him naked, and offer to dry him off.

When I did walk in, Harv was just emerging from the shower stall.  He had a surprised look on his face.  I held up a towel (sort of covering his lower body from my view), walked toward him and said, "Barb said I should dry off that hairy body of your."  Without waiting for a reply I began using the towel to dry his upper body as our eyes met and I smiled.  I am sure my smile was more of a smirk on my face.

Harv just stood there, not saying a thing... with a smile beginning to develop on his handsome face.  He let me dry his upper torso and arms.  Then I moved lower.  As the towel dropped lower I got my first look at his impressive, uncircumsized cock.  I could not help myself.  I exclaimed, "My... no wonder Barb is always so happy!"  Then I used the towel to dry his legs... finally moving the towel up between his legs to dry his cock and nut sack.  I lingered there, playing with them through the towel before I heard Barb behind me say, "Happy birthday Harv.  Enjoying the special service?"

Harv grinned and said, "You bet!

Hearing that, I followed the instructions my sis had given me earlier.  I bent forward, pulled the towel away,  used my hand to cup his growing cock, and kissed it right on the head.  I heard Harv moan.  Then I raised up and Barb and I led Harv to their king-size bed.

Barb had already pulled the bed covers back, and had platters of food set out.  "Lay in the middle," she instructed Harv, "your special birthday dinner is ready."  He did, and Barb and I began a seductive wiggle as we shed our baby dolls to Harv's appreciative grins.  

As soon as we were nude, we climbed onto bed on either side of him and began feeding him bites of shrimp, fruit, cheese and crackers.  "This is your special birthday dinner," Barb proudly told him. "Like it?"

"What could be better," Harv replied.

During the time we were feeding him, and eating nibbles ourselves, we casually let our boobs drag along Harv's hairy chest.  He really is a 'hunk!'  Not sure what he should do, Harv kept his hands to himself for a while.  Finally, as we had earlier planned, Barb began playing with Harv's cock before giving it a kiss.  That shrouded cock of his immediately shot to attention.  

Then Barb moved between Harv's legs and began mouthing his nut sack.  That was my que to bend down and begin giving Harv a blow job.  I was a bit nervous... but I followed our plans.  I was on my knees, working my mouth up and down his cock when I felt his nearest hand begin to fondle my nearest breast.  I had to admit to myself... it felt good!  I was really getting turned-on by this unusual situation. 

There I was, giving my brother-in-law a superior blow job, my sister was sucking his nuts into her mouth and stroking his legs, and he was playing with my breast.  Although I had seriously questioned my sis's plans for this evening, it felt... well, it felt wonderfully warm and cozy... and sexy!  I realized that I was becoming comfortable with the whole scene.  I also realized that I was was quite arroused as I felt a bit of moisture gather between my legs.

I guess Harv noticed that too.  Soon he had twisted his upper body toward me, and the fingers of his other hand were probing my pussy.  Eventually Barb moved up next to Harv, on his other side, and began to neck with him.  Soon I heard her ask, "What do you think of your special birthday gift, baby?"

"Wonderful.... wonderful!" is all he replied.  That positive reply was my next que.  Acting more confident than I really was, I swung my body around, straddled his loins (facing my sister and her sexy husband), and positioned myself above his very stiff cock.  As they watched, I let myself slowly slide down until Harv's cock head touched my pussy lips while I held onto the base of his cock.

I held myself there, as we had planned, as my sis kissed her husband again... and asked, "Want to be inside her?"  

"Oh YES.... Please!" he replied.

Barb looked back at me, and winked.  I let my body slide lower, using my hand to guide my brother-in-law's impressive cock as it began its trip into my body.  When I was fully seated against his groin, with his cock fully within me, I let out a deep breath I had been holding back.  "Does that feel as good to you as it does to me," I asked.

Harv's eyes had narrowed.  He said, "Your pussy feels like velvet... like a hot velvet glove gripping my cock!  I can't tell you how good it feels in there."  Barb giggled and gave him a big kiss as she snuggled against him.

Barb had already warned me that Harv would have a hard time holding back on his first orgasm after entering me, but that after recovering from his first one, she said he could go for a long time.

As I watched them kiss and cuddle, I began rotating my hips a bit, causing Harv's cock to move ever so slightly within me without letting him really pump in and out much.  The strange scene (to me), my prior mental stimulation as I anticipated this moment, and the feel of Harv's large cock inside me all worked together to begin sending shivers of pleasure through my body.

I felt myself involuntarily sending messages to my pussy muscles.  They began clenching tightly against the cock within me.  I slowly raised my body a few inches, my pussy quivering as it alternately squeezed and released its grip on that wonderful cock.  When Harv realized that he had some room to move he began to raise up and press himself back into me... deeply.  My eyes were closed, and I felt my body shake in enjoyment of the feelings at my crotch... feelings that were by then sending waves of pleasure up my body.

I heard my sis and Harv exchange soft mumblings of love for each other as I felt Harv continue his plunges in and out of my body.  By that point I was running my hands through Harv's mat of chest hair as I partially supported myself.

All of a sudden Harv's hips jerked and he began pounding up into me.  That's when it hit!  My body began to tremble, and I found myself fucking him back... fast!  I lost my breath momentarily as flashes of light began going off in my head.  Then I felt him expand... and then squirt inside me.  That really sent me over the top!  In my revery I managed to open my eyes just enough to see my sis hugging Harv... a wide grin on her face... and a look of anguished pleasure on his.

A few more jerking thrusts from Harv, and he stopped.  I fell over onto the bed next to Harv, opposite my sister.  I was enjoying an afterglow of warm sensations still coursing through my body as I lay next to him, facing up, as he was.

I heard my sister break into more giggles of self-satisfaction.  She knew that her plans had been successful.  Both Harv and I were clearly sated... at least for the moment.

When I had fully recovered, I opened my eyes.  Barb was playing with Harv's semi-limp cock as she kissed his chest.  I felt his hand on my leg... moving up... cupping and carressing my mons.  It was still overly sensitive, and I jumped a little.  His hand  moved up and over my tummy, gentling carressing as it went.

We lay like that for some time.  Then Barb and I again began to feed morsles of food to Harv and ourselves.  By that point I was fully at ease with the situation.  Harv alternately took one of Barb's or my breasts into his mouth for prolonged, gentle sucking.

Barb's continuing hand ministrations to Harv's cock had restored it to hardness.  Barb rolled on top of Harv and inserted his re-hardened cock into her pussy.  She began riding him much as I had done earlier, but more agressively.  Harv put his arm around me and pulled me tight against him, my head on his chest.

I heard Barb's breath quicken as their loins ground against each other.  It was strangely pleasant to be held tightly against Harv's warm, hard body... watching the place where his body joined with Barb's.  I had never before actually seen two bodies screwing (in person).  It was as though I had a ringside seat... and I was enjoying it.

I looked up to see my sister's face contort slightly in pleasure.  She was cumming!  I had to admit to myself that I was enjoying being up-close to share in enjoying her moment of sexual fulfillment.  This time Harv didn't cum.  As my sister pulled off him, his cock was still stiff and shiney. 

Some minutes later I ended up in the middle with Harv cuddled against my back, and me hugging my just-sated sister.  I felt Harv's still-stiff cock against my back.  He moved down, and soon he had it between my legs.  As I lay on my side, holding my sister in my arms, she reached down and raised my upper leg a bit, and Harv slid back into me.  It felt good to have him inside me again.  

Since my sister had obviously just enjoyed a fabulous orgasm, and since the sensations of my own previous orgasm had subsided, I welcomed Harv's pussy-filling manhood within me again.    

I seem to have more vivid memories of this second screwing than the earlier first one.  It felt SOOOO good!

Harv pumped ever so slowly at first as he reached around and cupped my nearest tit.  Barb opened her eyes, smiled at the sight of Harv's hand on my breast (and obvious awareness that he had slid inside me), smiled, and said, "Give him another good ride baby sister.  That's what she had always called me as I was growing up... 'baby sister.'

I began to buck back against Harv each time he pressed himself deeply into my body.  Barb twisted onto her side, facing me (nearly face to face) and wrapped her upper arm around me.  I was literally sandwiched between them... tightly sandwiched.  Then I felt Barb's other hand snake down between us to feel her husband's cock as it slid in and out of me.  It felt weird having my sis's hand there.  But it also felt good.  She knew right where to press against my clit as he went in and out.

After many minutes of this rather leisurely screwing... and sensual carressing by my sis... I experienced another extended, deightful orgasm.  Barb kissed my closed eyelids as I savoured the sensations.  Harv stopped only momentarily.  Then he resumed his gentle movements in and out of my pussy.  This time my pussy did not develop that post-intercourse excessive sensitivity, so I immediately found the renewed action enjoyable.

We must have laid like that for 40 minutes or longer.  During that time my body reached numerous peaks of pleasure and i felt my pussy squeeze down on Harv's enjoyable cock.  He still never came!  Eventualy Barb began playing with Harv's balls (between my legs).  I think that magnified the sensations he was enjoying, and he began to pump faster.  Soon I had one last... gigantic... orgasm, and this time Harv shot his pent-up load into me.  Wow that felt good!

After a bit more resting, we all got up and took brief showers to wash the stickiness away.  Then Harv lay back in the middle of the bed and Barb and I cuddled on either side of him.  with our heads on his chest.  he wrapped an arm around each of us... and soon we were all three in a deep sleep.

During the night we had rolled apart, so I did not feel it when they got up out of bed.  When I got up I found that Harv had already left to run some errands, and Barb was making breakfast for us.  As we ate, Barb thanked me for helping her give Harv a "special" birthday present... and I assured her that I had enjoyed every bit of it.

It was girl talk thereafter for a few hours... talking about each of our preferences in sexual fun... giggling... and talking about the evening to come.

That night found all of us in bed again... all nude of course.  This time Harv had a special request.  He wanted me to lean against the headboard with my legs spread so my sis could eat me while he took her doggy-style.  I was QUITE hesitant at first.  I had never had a female eat me.  Barb... however... was surprisingly receptive.  Apparently she had done that once before.

I thought, 'What the heck,' and complied by assuming the requested position.  Barb laid on her tummy between my widely-spread legs, raised herself on her knees, and Harv got behind her.  As soon as Harv had entered her pussy, my sis grinned up at me before laying her face in my crotch.  She began to lick all aorund my pussy and clit.  It felt good.  I decided to just close my eyes, lay my head back, and enjoy the sensations.

Soon I felt the bed move as Harv pounded against my sister's up-turned ass.  When he saw that I had opened my eyes, Harv just smiled at me as he continued his ride.  Barb's tongue was buried deep in my pussy, circling around and giving me some really enjoyable sensations.  Then I heard Barb mumble that she was cumming.  She pulled her mouth off my pussy and began to moan.  Harv speeded up and soon they came at nearly the same time.  

After a few minutes of resting, Harv announced that it was my turn to assume the doggy-position.  Since I had not yet cum, I complied immediately.  I had my head resting on a pillow... and Barb... still recuperating... was laying next to me.  Since my pussy was wet from my sis's ministratons, and since Harv's cock was sill wet from cumming inside my sis... he slipped easily into my pussy.

He not only slipped in... he drove himself balls-deep into my body.  I could feel the head of his cock tapping on my womb.  He changed his pace numerous times during that night's shared screw.  As he screwed me, Barb moved over next to me and kissed my forehead as her hands carressed my body.  Eventually she again put her hand under my tummy and onto my mons, gently pressing in each time Harv's cock thrust inward.  The combined internal and external stimulation felt very good!

I felt Barb get up out of the bed and noticed through the wall mirror that she had moved behind her husband.  I learned later that she had positioned herself between his legs and was sucking on his hanging nut sack as she grasped the base of his cock on each outward stroke from my body.  That caused Harv to screw me with increased vitality.  I felt his cock expand and shoot... but he kept going for several more minutes until my body twisted in orgasmic release.

We slept like we had the night before.  The next night I moved into their spare bedroom where I stayed for nearly two weeks... until I found my own place.  Yes, during those two weeks I visited their bed several times, and one night Barb sent Harv in to sleep with me.  Believe me, I enjoyed lots of really satisfying sex during those two weeks.

The night Harv slept with me, Barb's friend Martin came over to "service" her.  By the sounds they made, I think they both enjoyed everything they did.  They no doubt heard similar sounds of shared pleasaure coming from my room.  I never did screw Martin during those two weeks, but I did on a few other occasions when I visited Barb and Harv, and Martin was joining Harv in "doubling" Barb's pleasure.

Since my sis introduced me to FMF threesomes with Harv, I have had the pleasure of joining several other couples they introduced me to.  More about that in my next story.
