So my girlfriend and I at the time were college students. We lived in an apartment near campus in always had friends over. We met in high school and had been dating for a few and currently enrolled at the university. My girlfriend at the time was very curious and never backed down from any of crazy dares I dared her to do.

Since we had been dating so long, we always tried to spice up our sex life. We did this by daring each other to do things naked or trying new things in bed or even using new toys from the sex stores. We never took it too far and kept private about our sex lives.

One day I threw a party at my apartment, and we all had a lot to drink as well as a lot of fun. Once it got late and most of our guest had left but still had a few people that decided sleepover. There's probably two guys who slept on the couch, and they were very drunken entirely passed out. One of my close friends slept in the study room by himself and was also a bit drunk.

My girlfriend and I went back our bedroom As we were pretty tipsy as well. Once we got to the bedroom, she changed into one of my T-shirts and just her panties. When she climbed into the bed next to me, we started making out and having a little fun with each other and teasing each other. That was when she mentioned that we had to be quiet because we had guests in our living room and study room. I tell her not to worry and that they were passed out drunk. I told her that they are probably so drunk that she could walk around without any panties on and a T-shirt and they wouldn't even notice, but she begged to differ.

when the fun starts

So this is when I dared her to do exactly as I had said earlier about walking around half-naked as well as adding the part of walking into the study room without her panties on as and to pretend that she had to use the computer. Since I was A bit drunk, she said she would go along with it if I walked behind her while holding her hand.

So she drops her panties while teasing me a bit and throw them at me, and we slowly open up the living room door without having the door creak, and I let her walk out 1st in front of me. The shirt is barely covering the top of her ass, and her nipples could be seen through her shirt. Since it was dark no one noticed us in the living room Also the fact that they were pretty drunk and knocked out helped as well.

Next, we made our way past the living room and into the study room. We slid the door open and found our friend asleep on the floor. We close the door behind us, and I take a seat on a computer chair as she sat on my lap. She begins to turn on the computer, and the lights from the computer dimly start to light the room.

Once the computer and monitor turned on it begin to brighten the room up and started to wake up our friend. The light started to wake him up, and this was when we lied to him and town we needed to use the computer quickly, and we will be out the room soon. For fun, I pull up some porn and start playing with the volume set so everyone in the room could faintly hear it. I also then start playing with my girlfriends pussy. She tries hard to hold her moans in but after a while can't. Our friend at this point is asking if we are watching porn together. I tell him yes we are And that he is free to join us. My girlfriend looked at me and gave me a look of concern and surprise at the same time. I end the end pulling off my boxers and let her sit on my lap again so that she can stroke my cock as I rub her. We continue doing this for a while as he watches us in a daze since he was still a bit tipsy. At the same time, he also strips butt naked and says he might as well join in on the fun.

He comes and stands next to us with his semi-hard cock out. We were all watching the screen as my girlfriend was still rubbing my cock as I was running on figures up and down her wet clit. I whisper over to her to take off her shirt as well since my friend, and I were both naked. She quickly agrees to, and I pull off her shirt then turned around and asked my friend if he is enjoying the view to which he also immediately replies with a yes.

A little background on my friend... HE is a bit socially awkward and had a hard time meeting girl but was still a laid back and fun guy to hang out with; also, my GF had only been with me since high school and never had any other cock in her.

Back to the story

My GF and I always had a fantasy of someone watching us as we had steamy hot sex. So I had her stand up and lay down on the ground. I settle down next to her so we could go back to frolicking with each other. My friend lays down next to me as well. While my girlfriend is rubbing my hard cock, she glances over at him and notices that uncut and she says she's never seen an uncut cock before. After I hear that leave her lips, I immediately tell her to go ahead in touch his uncut cock and see how it feels. While still rubbing me she uses her other hand to poke at it a little bit and then eventually starts rubbing it up-and-down so she can see the foreskin moving back-and-forth. She was smirking like a girl in the candy store who had two lollipops in her hand at this time.

After a while, she leans over to my side so she can start sucking me off as she still plays with my friend penis. I tell him the go ahead and touch and feel her lovely breast.

Finally, I get so horny, that while she is bent over, I get behind her and start doing her doggy style. While I'm still doing her from behind, she begins to moan very loudly and starts to lean on my friend's incredibly hard cock. She looks like she about to do a yoga pose with her ass up in the air and her face down towards the ground. I keep getting faster and faster until her face is so low that She has no choice but to start sucking the cock right in front of her face. We still have some guest in the living room so I'm guessing she used his cock to drown down her moans so no one else would walk in or overhear the noises.

After changing a few positions as I was fucking her and he was following her mouth. She was doing an excellent job of keeping us both satisfied. She did give some of the best blow jobs I had ever had.

Finally, I step back and smack my girlfriend's ass. This was when I asked my friend if he wants a go at it as I catch my breath. My girlfriend grabs my arm tightly and moves me in front of her as my friend takes her from behind with no condom. He ends Not being able to last too long since he has whiskey dick but does get a good few minutes of pounding her soaking wet pussy. I end up behind her again as he moves to her face. I give it my all and go as fast and hard as I can until I bust all over her ass. She ends up cumming and squirting as well which leads her to lay on the floor for a bit. My friend goes back to the bed disappointment since he was having issues with not being able to stay hard. My girlfriend and I catch our breath and grab our clothes and walk back to our bedroom naked, thankfully none of the guests in the living room see us.

She goes to the bathroom and cleans up quickly. We get into bed next to each other with no clothes still on. Both our hearts are beating rapidly and can't believe what happen. We were both are still pretty turned on about what just happened and ended up having a quick sex session again but even faster, harder and rougher while calling her a slut and dirty girl.

The next morning we woke up and found all our guest gone. My girlfriend and I still couldn't believe what happen and found it to be sexy and to be one of the most heated moments in our sex lives.

We are still pretty close friends to the guy that joined us that night and ended up planning a few more threesomes with him.
