two_fister: I've been caught a few times, but these two stand out.
The first time was right after bar time and my kinda g/f at the time and I had just gotten home, this girl always wanted sex anywhere, everywhere. So we get to my place, and one thing leads to another, we start fooling around, and she starts giving me a blow-job. Now this in and of itself it not stange at all, what was strange is that we were on the kitchen floor at the time. After about 5 min. my roomate at the time walks in. The kitchen was in the back of house, and we hadn't heard him get home. What was really funny is that she kinda kept going and my roomate walks in, looks, smiles, then walks out.
The other time involved another ex-g/f. We thought we had her place to ourselves, so we didn't bother closing the door to her room when we started having sex. Anyway it was getting pretty loud and intense, so loud that we don't notice her roomate and roomate'sb/f are home. Turns out they'd been home a while. This isn't all that strange, as I'm sure this kinda thing happens a lot.
But it stands out 'cause of how obnoxiously loud we were being at the time. All fours of us had good laugh the next day.
