Hello. This ia a Mature story. A 20-something guy and his friends go to Vegas. They run into his coach's mature wife, her sister and some of her friends. The groups have drinks together, get too drunk, some making out starts. The protagonist and the coach's wife go off on their own, buy her a bikini for the hot tub in his room, have sex on the floor, carry on. Does this ring a bell to anyone? I can't find it in lit, on google or other search engines, or on the wayback machine. I believe it was called An Old Friend in Vegas, but like I say that doesn't come up. I suppose it may have been on xHamster stories which are gone now. Anyone have any ideas?? Thanks so much!
