Double date (crossing the line)
I've been dating this chick Lauren for about a month, and I like her a lot. We've been getting more serious, and I think I love her. My friends are important to me too, and recently we went out with a buddy of mine and his girlfriend. We had a good time socializing, dancing, and we went back to my place for drinks and a movie.
All four of us were on the couch and as the night went on we did some making out with our girls. Other than some heavy kissing and rubbing, I didn't expect more. Lauren then said "I wanna fuck you" and I looked over at my friend and his gf and they both just nodded like that was okay.
Lauren started riding me on the couch with our friends about a foot away. My buddy started getting his dick sucked by his girl. While I was getting fucked by Lauren, I noted Lauren reach over and grab my buddy's cock and give him a few strokes as a handjob. I told her to stop it, "Don't touch him", and she stopped.
I don't mind fucking in front of friends, I've done it before, but I'm not into swinging or swapping with people I care about, and I think Lauren crossed the line by touching my friend's dick. She said she was just helping him feel good, but I told her that I don't want her to be a slut. She said it wasn't slutty at all, but I disagree. Anyway, we're not going to double date with those friends anymore, because I don't trust her instincts. I don't mind if she's kinky with me, but it has to be only with me.
Get over it. If you're going to fuck so your friends can watch, be prepared for them to join you. After all if you're open to them watching then they're going to assume you're open to other things. If you don't want to share your girl then you better find another because this one apparently was open to the idea of enjoying another cock, and likely another cunt. And that doesn't make her a slut, that makes her a woman who likes to experience what her body can do for her. I'd rather have her in my life than a prude who won't even show some cleavage.
