[MF] Milf grinds me in bar to orgasm

I was at a friends birthday and I was sitting at a table with everyone around, kind of a tight squeeze between the two tables we were at because of so many stools and people standing around. All of a sudden one of the girls friends walks over and squeezes by grinding her ass deliberately all over my crotch literally forcing my legs to open. I was wearing silky type shorts and she had on a thin clothed dress. Her ass felt so good and she was doing it on purpose acting like she was just standing there with no room to get by and was still talking to other friends of hers at the table across. I was surprised at first then spread my legs for her to really grind in. I realized she was doing it on purpose, I was right between her cheeks and she had a pretty big soft ass maybe in her 40’s. kinda thick. blonde and sexy enough for me! lol the clothing was perfect for the situation. I was sitting with my legs spread and she knew exactly what she was doing and went for it. Then I felt her start to clench her cheeks on my cock. I was rock hard and was pretty nervous someone would notice my face or see what was happening lmao! she kept flexing her ass and my cock was literally wedged as deep between her cheeks as we could get with our thin clothing. every clench of her ass made my cock throb harder. i spread my legs as much as i could to let her get in good. one of the hottest things to ever happen to me. I was sitting with my other friend talking to him and still surprised and in disbelief kind nodded at him what was going on. i was loving it. Her ass was so soft lol. she squeezed my cock with her ass so good. it lasted for maybe 5 min.. and I eventually came lol got hot and sure was red in the face lol. she felt me cum throbbing and unwillingly shaking my legs a bit. no one realized it. besides my friend i nodded to and was like “holy shit” haha!! he was surprised too. He actually knew her and she was married to another friend of theirs. He didnt see me cum but as soon as i did she knew i was done and simply let off and then squeezed through a few other people a few seats down still standing between tables. A few seconds later she squeezed back through and tried to apologize saying sorry for grinding my ass all against you All my friends are at that other table, I didnt realize I was at the wrong table. she was joking with me… I said no , its completely fine dont worry about it, lol!! we stared at eachother for a sec and she left me alone! lol I sat there finished my beer with cum running between my legs then eventually got up went to the bathroom and cleaned up. I should have tried to take her home but I knew she was married and figured she already gave me what she wanted to do. I get so horny thinking about it still! I want it to happen again so bad lol. I know ill see her again eventually. I want to feel her ass again. best. thing. ever! lol
