Me and my girlfriend were at the beach in between two groups. One group of big slutty girls and another large group of sorority type girls with amazing bodies. One of the big girls was making sand castles bent over in a thong, completely exposing her fuck holes. My girlfriend found it amusing, while I found it so arousing. I could see a bit of her beautiful asshole. So slutty and I loved it. At some point an older man showed up, seemed to be in his 60s. He just sat there by himself, enjoying the group of sorority girls. My gf made a comment about him starting at them, but all I could think about was jacking him off . I wanted to jack him off while he stared at them. If I was alone I think i.would have asked him if we could sit in his car together so I could jack him off. I like the idea of helping a man cum, convolsing and moaning to cumpletion. I've never done that t, but I want to.
