My wife's personal PT has let his fingers linger over her mound and ass a few times. He is only 26 but excellent guy and good at his job. Its onle $30 in Colombia to have a guy come to your house for a full 60mins. So when she is down there, I tell her to get all the therapy she can.
Anyway, she finds its easier to strip and lie down in her thong. Its the best way for him to massage the buttocks, sciatica and all. So his hands invariably slide up, around the butt and even between cheeks. She never tenses when she feels him meander over. So that is a sign that she is OK with him having a bit of fun. Same when she is face up. She laughs and says Aw, Im sure you have seen younger and better tits anyway. He blushes. Wif'es tits are fake Ds with hard nipples. But his hands run up the legs and his pinky finger hits her mound. Again, she is a confident 51 yr old slut and lets the boy do his stuff.
So, no wild affairs, just a bit of fun with a guy younger than our own sons...
