Sex with Friend's GF and Her Friend

My buddy Justin and I were in our first year of college, his gf Erin and her friend Jennifer just finished high school. One summer night we were at his parent's house in his old room watching a movie together. My friend and his gf were on his bed, her friend (whom I was not dating or seeing) and I were on the floor with a bean bag chair beside his bed.

Erin is about 5 foot 6, tanned, thick swimmer and cheerleader body, long black hair, I'd guess small B cup boobs, really thick thighs and a big, round ass. Jennifer is 5 foot 8, kind of pale colored skin, brown hair, huge H cup boobs (from what she said), and slightly on the chubby side with an extremely cute face, also with a big round ass.

Jennifer and I started touching each other and making out, we heard noises and glanced up to see Erin sucking Justin's dick. It was hot watching it and I was surprised at how they were openly messing around in front of us since I've never known them to be like that before. Jennifer started taking her shirt off and bra, I started taking my shirt and pants off, we made out a little bit more and she worked her way down to my dick and started to lick and suck on it.

Looking above on the bed, Erin started to get completely nude as well as my friend, I've never seen his gf nude before but she looked stunning with tan lines on her boobs and and bikini area. She mounted Justin and started to ride him. I turned away and looked as Jennifer giving me head, she looked up and me and also mounted me and started to ride me. Hot moans and screams were filling up his room and both of us were having sex in multiple positions. When I was finally about to orgasm, to let Jennifer know and she took my dick in her mouth and swallowed my jizz. Just always used a condom and they were in doggy style position when he finished, afterwards we lied down and ended up falling asleep, with Jennifer less than arms length away from me.

Early morning, I always assumed like maybe 3-4am, I woke up to what sounded like a person moving, I figured it was someone getting up to use the bathroom and shut my eyes again. Then i heard the sound getting closer to me and felt a hand cover my mouth and then I heard a whisper in my ear that said "if you can be quiet then we can have some fun". I then felt the blanket I was using lift up and a hand slide into my shorts and start feeling my dick and balls and I started to get hard and then another whisper saying "you're dick feels thicker than Justin's". Then it hit me, it was Erin and I felt my heart race and she then told me to "sshhh" and she leaned in and gave me a kiss on the lips and as she let up, she gently bit my bottom lip.

She then lifted the covers and I felt her tugging on my shorts to pull them down then I felt her hot breath around the head of my penis, she then grabbed my dick, gave the head a slight lick before I felt her lips and tongue completely around my dick. She started giving me one of the best blow jobs I have ever had in my life. She rotated between slow and sensual to aggressive and sloppy. After a few minutes she stopped and she started moving back towards me. She gave me another kiss on the lips and then leaned in and shoved her boobs in my face. I started to lick and suck on them and she was letting out soft moans. She then started to mount me and I felt a sudden warm, gooey, wet, sticky sensations around me dick and she let out a semi loud yelp. I thought it was going to wake someone up but that didn't happen.

Erin's pussy felt incredible and she started to ride me slowly then worked up the pace. She started to moan louder and eventually was biting her arm and leaning into my shoulder to help keep quiet. I'm not sure how long she was riding me but I knew I was getting close to cumming, so I told her she was about to make me cum, and she whispered "I'm about to cum again so I'm not stopping". I kind of felt my heart skip hearing that but in no time at all she leaned into me and bucked her hips and I could feel her body spasm and then I had what I fell was the most explosive orgasm inside her pussy. It was pretty hot cumming at the same time she was. She then laid on top of me for a few minutes and we started kissing lightly with each other then she got off of me, left the room (assuming to clean up). I turned and listened but it never appeared Jennifer or Justin woke up at all and I started feeling this guilty, anxious feeling about fucking my friends gf. Erin came back into the room and I could hear her get back into the bed with Justin. I eventually fell asleep after that.

When we all finally woke up we just started talking about the previous night and how fun it was and my friends said it would be hotter if next time we have sex with different people. Erin just kind of gave me this look and grinned but we agreed to it for the next time we had a get together.
