Hello GAF! Here's a confession.
In college i was dating this girl, and she was kind of crazy. Not actual certifiable medicated crazy, but just a hair above "super posessive and manipulative girlfriend" crazy. I didn't realize it at the time, and it actually even took me several years after the final breakup to think back on some things and think "Wait a second...that was kinda fucked up of her," but she was pretty bad.
Anyway, this one time about two years into our relationship, we had a bad fight. I technically had a dorm room, but for all intents and purposes I was living with her at her apartment. So we have this blowout fight over something dumb, and I say "Fuck this, I'm going over to Billy's, I'll see you tomorrow," and I walk straight out the door. I hear a pint glass shatter against the door after I leave (I know it's a pint glass because I see the pieces in the garbage later on, but anyway)--not soon enough after that I'm concerned she was really trying to hurt me, but still kind of a crazy thing to do.
So I leave. But I don't go to Billy's.
I message my ex girlfriend. Who, unbeknownst to my then-current girlfriend, lived two apartment complexes over. I tell her I'm in a shitty mood and ask if we can hang out since it's been a while and offer to bring beer, and she says to head on over.
Now, I've never been the kind of person to do this sort of thing - before or since this incident - but I was starting to get to the point where, deep down in my gut, I knew something was wrong with the relationship and that it probably wouldn't work out. On top of that (or because of?) I was starting to miss my ex (and her 38DD's). We were each others' "firsts" and she eventually dumped me to sow her wild oats or whatever, but we were at the same school still, and though we didn't communicate too much anymore, we talked enough for me to know that she was currently unattached...
So I went over there, we get drunk, reminisce, laugh about better times, and eventually start fucking like rabbits. We fucked like we had both been poisoned and the only antidote was inside the other person's genitals. The condom broke (she is still the only person I've managed to break a condom with) and I finished inside her but she said it was fine because she was on the pill anyway and that was good enough for me, so we went to bed.
(I didn't get her pregnant, so don't worry if you think that's where the story is going)
Next morning we wake up, and I'm feeling slightly shitty about what happened since I'd cheated on my girlfriend. My ex, though not feeling as bad about it as I was, asked that I not tell my current GF about what happened (maybe she caught on to the crazy quicker than I did), cleans up, heads out to work, and tells me to lock up behind me. I take a quick shower, put on the same clothes I wore the day before, and leave.
I text my GF that I was headed back home and would be there soon, she responds only with "Ok."
I get there with my mind still racing, thinking about what happened the night before and what I should do about it. I fumble with the lock, get the door open, and immediately hear my GF.
"Anon, is that you? I'm in the dining room, come here."
I head into the kitchen/dining area, and there's my GF wearing nothing but a fishnet bodystocking, bent over the table and waiting. I guess this was her way of apologizing for the previous night's fight. It took my twentysomething still slightly drunk college aged guy brain about two seconds to decide how to proceed. I fucked her too, right there at the table. Normally I would pull out, but at the last second I had sort of a twisted thought remembering what happened the night before, and I finished inside her, too. Never mentioned what happened to her, and we actually ended up dating (off and on) for another four years after that.
My confession isn't that I successfully bedded two women in less than twelve hours (though it kind of is, since I've never told anybody about this incident). It's that for the first and only time, I cheated on a girlfriend. And the thing is, I never really felt bad about it. I still don't.
