My friends and I made it home from a day drinking party and were planning on staying in for the night. My one friend talked me into going out with him to a local bar along with his gf. When we got there the place was empty except for one of my friend's high school buddies. I sat on the far end of the bar, his gf next to me, then him at his friend. While they were engaged in conversation about high school, me and his gf were making chit chat. We were pretty friendly but nothing sinful. At some point she got up from her chair and came back and was standing with her back to me facing her bf. I don't know if it was the copious amounts of alcohol we drank, but she ended up backing into me and I couldn't stop noticing hot great her ass and legs were in the skirt she was wearing. Any inhibitions I had earlier in the day were long gone. I moved my hand from my waist to the bar and brushed her inner thigh, in a way the could have been construed as an accident. Instead of turning around and responding she instead moved her body closer to mine while facing her bf. Almost on instinct I made another slow move to my beer, this time letting my hand linger a little longer on her thigh. Again she moved a little closer to me. I carefully positioned myself so as to not attract attention, and slowly began running my hand up her leg until I reached her panties. I rubber her clit through her underwear and she was pretty wet. I slid her panties to the side and started going to town as discreetly as possible. When I felt as though we were about to be caught, I pulled my hand out. She turned around and grabbed my hand and put it back where it was. I could tell she was extremely drunk and we could get caught at any moment so I stopped entirely and closed out my tab. My friend (who did not notice) closed out his tab and we left the bar. On the walk home, his blacked out gf was trying to get me to go back with him and her for god knows what. I politely declined and went home. I started getting texts and phone calls from her, when I rationally responded with "good night" and "I had good time with you guys". When I woke up the next morning I had one text from my friend that said "what the fuck man". I just froze in bed and was just waiting for him to knock down my door and deliver justice. After a couple of hours he responded back "sorry my gf was blacked out last night" and I immediately exhaled. It's been a few weeks and neither of us has said anything to the other or acted any different which leads me to believe she doesn't even remember. I'm going to wait for her to say something if she wants to, think that's a good plan?
