I was in my early 20's running with a diverse group of weirdos. Somehow nor other, I ended up getting all drunked up and banging this 20ish cousin of one my friends. She was visiting with her 18ish sister. She was super needy which stroked my ego quite nicely and fed a really cruel streak. I'd only fuck her when I was really drunk and everyone else was asleep. She started telling people we were going out and when questioned I'd deny it. So one night I'm all shitfaced and we're making out. She's telling me she loves me and I'm saying "I know". I'm classy. So at some point it hits me that maybe a 3way with her sister might be a hoot. If nothing else, it would most likely make her hate me. So I start asking her how much she loves me. Oh, so very much. Enough to wake up your sister? Everything stops. Why? Maybe she'd like to have some fun too. She's not all for this crazy idea. Eventually I pressure her into it. If you love me, you would. Needless to say, her sister told her she was out of her mind. And my secret was out, because I'd been denying I was banging her. Ah, to be young again.
