Anyway, one weekend Sarah and myself were visiting her family, we were spending Friday night in and we would be going out on the Saturday. On the Friday we really just caught up with her family watching TV etc until around 10pm when I said I wanted to go to bed, so Sarah and I went up stairs to the spare room leaving Sarah's mum and dad and Rebecca down stairs. As I lay on the bed (fully clothed) Sarah went to bath room. A few minutes later the door opened and I felt what I thought was Sarah climb on & straddle me, however as I moved my hands up from her waist to her breasts I could tell something was different..... it wasn't Sarah it was Rebecca dressed in Sarah's top to confuse me, as I looked over Rebecca's shoulder I saw Sarah peering in through the door laughing her head off.
Rebecca got off me and I didn't think anymore about it, we all sat on the bed and stated talking. After 15 mins or so the subject turned to sex, and the fact that Rebecca was still a virgin was discussed. Sarah asked her had she ever seen a cock, Rebecca said yes, in fact last week, she had wanked a guy off for the first time, someone that she had been seeing. My girlfriend asked if she had enjoyed it and Rebecca said yes, then Sarah asked her if she wanted to see my cock! So I'm led there and they are talking like I'm not there, and even though of course I'd love this 19 year old to see my cock I am actually embarrassed and hesitant. Then Sarah undoes my trousers and opens my boxer shorts, my cock is semi rigid but led on my tummy, still partly covered by my clothes. Sarah asks Rebecca what does she think of it and Rebecca says "well I can't really see it, its still covered", with that, Sarah pulls it right out, gives it one stroke and its fully erect looking at Rebecca, her eyes are focussed right on it. Touch it Sarah says to her, I can't believe it and I'm thinking quick touch it in case Sarah changes her mind. Rebecca leans forward and touches it, firstly very awkwardly just with one finger, but then wraps her hand right around it and moves it up and down, a drop of pre-cum presents itself, she "accidentally" touches it, her young hands looked fantastic.
Then Sarah asks Rebecca whether she has ever given a blow job, Rebecca says yes, last week when she gave the hand job (from her face I think this was a lie), she says however that she would like to see "how its done properly" and with that Sarah moves over and takes me in her mouth, giving me a little hand action at the same time. This goes on for a few minutes, all the while I'm watching Rebecca who is watching Sarah suck my cock and its horny as fuck. Then without hesitation Sarah tells Rebecca its her turn, at this point I think I'm in heaven, I'm 28 and I'm about to go into a virgin 19 year old mouth, wow....anyway, she moves over looks at me like she is thinking be gentle with me, its m first time and then she takes me in her mouth, its so wet and warm, I cold have cum there and then, but I wasn't sure what Sarah would say, so instead I make a mental note to take every detail in because I didn't expect it could ever happen again, so I do, I look deeply at Rebecca, she doesn't look at me as she is concentrating on what she's doing, I tell you her mouth was then, and still is today built for fucking.
