I was visiting my GF who I had only just begun to date. We both knew the relationship was purely physical and would never be anything serious. I had only fucked her a few times prior to this occasion. We were getting it on in bed and she asks if she could get her dildo out. Of course, no objection from me. I was fucking her with her on top and she was sucking off the dildo. I took it away from her mouth so I could kiss her. She would alternate between sucking the dildo and kissing me. At some point, she jokingly offered me the dildo, and I took it into my mouth. We both laughed and continued to fuck. During the next 20 minutes or so we were fucking and both sucking on the dildo. I was putting on a show for her because she seemed to get really turned on by the role play. All of a sudden she asked if I wanted the real thing? I hesitated because I could see she was asking seriously. I replied with a yes, and she said she can get someone right now if I wanted. I asked who? She said she's friends with a guy a few floors above, he would be very willing. I knew she had a wide circle of friends, including gay ones but I hesitated again saying I'm not sure if I really want to. She then became very seductive and after a few minutes I reluctantly agreed, still not sure but was just going with the flow. In no time she was off me and on her phone texting him. He must have responded straight away coz she said he's coming in 5 minutes!

I was horny as hell, this time mounting her from behind and the doorbell rings. She yelled come in and into the bedroom walks in this guy, he sees us fucking and immediately starts undressing. She gets up and makes a comment to him something like 'he's cute isn't he?' while caressing my ass, he replies like a kid in a candy store 'oh yeah'. I didn't know what to do at this point, so I just start making out with her and he walks to us and drops to his knees and takes me inside his mouth. He was actually quite good. Here I was making out with my hot and horny GF, and there's a guy on his knees sucking my cock. I was really enjoying the situation and was getting quite close but refrained from blowing my load into his mouth. She sensed this I guess and now almost demanding that it was my turn. I figured what the hell, gone this far now, might as well continue. I dropped to my knees, closed my eyes and went for it. To my surprise, it wasn't gross or anything. I used my previous 20 minutes of practice on the dildo to try and give him a good one. I liked the sensation of it getting harder in my mouth. Not the biggest cock in the world, mine was much bigger and thicker. I then felt her mouth on my cock and I was in heaven.

About 5 minutes of this and I was getting real close and couldn't take it anymore longer. I told her I'm gonna cum and got my mouth off of his cock and proceeded to really face fuck her, emptying my balls in her mouth, with two hands forcing her head onto my cock.

One of the best sexual experiences of my life but very quickly I came down from the high and got a little embarrassed and asked him to leave. Over the next few visits, the same thing has occurred, each time getting more comfortable with each other. Nothing like getting your cocked sucked by a guy whilst your girlfriend is whispering slutty things in your ear. He actually sucks it better than she does.
