FIL Harley Davidson Good Vibrations

My father in law is a tough and avid motorcycle rider. Unlike his son, my husband, he’s really rough around the edges. He’s all tattoos and smokes and drinks. I’m 27 now but at 23 I asked him if I could go riding with him having never been on a bike. I was wearing spandex tights and tight T. He said absolutely and so away we went with my husband’s blessings. Even though I’m very orgasmic, I did not anticipate the problem I had, that of my clitoris getting good vibrations off his machine. With every mile the stimulation grew more intense until as much as I tried not to cum, I did and did in a big way. I can’t be quiet when cumming and it became obvious to him just what was happening. He immediately pull off the road into a rest stop where I convulsed in orgasm aftershocks. He watch and laughed at my situation asking if I wanted a cig. What made matters worse, since I don’t wear underwear when wearing spandex, when I got off the bike the wet spot on the seat was large and in obvious view. I was embarrassed but that quickly disappeared when he put his nose to it made comment as to loving the smell and then licked it!
I normally would find that gross but it turned me on, that and the bulge in his pants. I wanted so bad to have him fuck me, something I had never wanted from him and he knew I wanted to be fucked. There was no one there so I walked over to a picnic table took my spandex down and one leg out, spread my legs and invited him to fuck me. He hammered me, his dirty hands removing my top and touching my tiny B cup breasts. His cigarette breath, his rough stubble on my face and tits had me so excited and I gushed in orgasm. He then pulled out licked my pussy juice and plugged me again until he filled me with his cum.
His son is a clean cut, clean shaved man, so I was shocked at how turned on I was to be man handled by his father who most certainly isn’t like his boy. On the ride home I must have cum easily three more times leaving one Hell of a mess in my pants and his seat. We have never told my husband, his son, or my mother in law about any of it. We have however gone for many rides and fucked every time, both of us look so forward to riding season and never have done anything outside our rides.
