My first bi-sexual experience came during my second semester of my freshman year in college. I had been dating Pam for some months and we enjoyed many nights fucking each other, On this particular night we decided to go to her dorm room. When we entered her dorm room, both of us noticed her roommate, Karen, sleeping. Making matters worse was that she was topless and her blanket was not covering her body completely, exposing one breast.
Somehow I managed to compose myself, difficult as that was with a hard dick and a nearly naked female in front of me. "Pam, maybe we should go to my place instead.
Pam looked at me then looked at Karen "Well, I'm horny now so lets have some fun". As she said this, Pam walked over to Karen's bed and firmly latched her mouth on Karen's nipple.
I stood there mesmerized like an idiot as Pam pulled down the blanket, revealing Karen's nakedness. "Well, what are you waiting for?" asked Pam as she lowered her mouth onto Karen's pussy.
I quickly got undressed and began sucking Karen's nipples. Soon we had Karen moaning and groaning in pleasure. Then Karen woke up "Ohh, Pam, you finally decided to share Jason. Can I suck his dick?" Not waiting for a response, Karen grabbed my dick and engulfed it with her mouth. Pam took this opportunity to get undressed.
Soon, I was lying on my back, my dick up Pam, and Karen was sitting on my face. The girls were French kissing and fondling each other's tits. I was in pure heaven, nothing could make this day bad.
Soon, a knock at the door interrupted our fucking, my dick deflated in fear. "RA, open the door". Oh great, I thought to myself, I'm going to be caught fucking. I'll get suspended and work at McDonald's for the rest of my life.
Karen got up and without bothering to put on any clothing answered the door. "Well, hello Brian, do you want to join our party?"
"Hell, yes" Brian said as entered the room, shedding his clothes. He embraced Karen, caressing her body.
Meanwhile, I upon realizing that my collage career wasn't in jeopardy, began licking Pam's pussy. When I lick pussy I tend ignore my surroundings. So when I felt a mouth engulf my dick, I thought it was Karen. When I looked up however, I found quite a surprise. Karen was being eaten by Pam, making physically impossible for her to suck my dick. Which left...
I looked down and saw Brian sucking my dick. Despite the shock of being sucked off by a guy, Brian was making my dick feel real goad. As they say, a stiff dick has no conscience. Soon, I was cumming in Brian's mouth. Brian moved over to the girls and shared my semen
Pam then explained to me that she was bi-sexual since high school and had seduced Karen within a month of rooming with each other. Brian, their RA (It was a coed dorm) had caught them in one of the study rooms. Rather than turn them in. He joined them. Brian was also, bisexual. They had discussed for a long time about including me in their group. Now that I know, will I join them?
There was only one way to answer in my mind. I grabbed Brian's dick and drew it to my face. It felt weird holding another man's dick. I looked at it, it was about 6 inches, mine is 7 inches, but his was thicker. Tentatively, I stuck my tongue out and licked a drop of pre-cum off the head. It tasted pretty good. I began to lick around the shaft. Soon I engulfed Brian's dick in my mouth. I admit I wasn't a good cocksucker, but Brian prompted my on, telling me what to do. I was rewarded with a mouthful of his delicious semen, which I barely could contain in my mouth. I swallowed as much as I could, knowing that this will not be the last dick I would suck. Brian then kissed me tasting his cum on my lips. It was different than kissing a girl, more forceful.
I sat there savoring the taste of my first blowjob, when Karen suggested that we do sandwiches. I asked what are sandwiches?
"While one of you guys is fucking on of us, the other fucks him in the ass!" Pam answered
Don't worry, I'll go first" Brian volunteered. He soon got on top of Karen and began fucking her. Pam was busy lubricating my dick with her spit, leaving my to lubricate Brian's asshole with my tongue. I had now problem with this. Pam had introduced me to ass fucking earlier in the year (a prelude to this, I wonder?) Soon I had his ass properly lubricated and I pushed my dick into his ass. It was tight. Soon we got a rhythm to our fucking. When Brian came in Karen's pussy , his ass muscles milked my dick, making me coat his bowels.
Then we switched. I began fucking Pam, while Brian rimmed me. Soon his dick began to enter my ass. The pain was intense, but soon gave way to pleasure. On the upstroke of my fucking, I forced Brian's dick further up my ass. Soon we all came. Exhausted we fell asleep. in Karen' and Pam's room.
The next morning, I woke to see Brian's soft dick near my mouth. Succumbing to temptation, I suck his soft dick into my mouth. It was Amazing feeling his dick grow. Brian began to groan and that woke up the girls. We celebrated all day my entrance to their group. When the semester was over, all of us moved out of the dorms and rented a house together. This was the beginning of many bi-sexual adventures for me.
