I had never felt this way before...I mean I never thought I'd be attracted to an older guy like Dr. Grant. Not for nothin' I mean, he's a good lookin' dude but, I've always been with young guys but there's something about my doc that triggers every horny bone in my body. When it was my time to do the follow up..I tried to play it off real cool but butterflies were in my stomach the moment he walked in. My heart must been beatin' a mile a minute when he checked my heart but when he told me he was gonna check my temperature rectally I literally got a chub in my underwear. I think my nervous laughter said it all when he lubed up my butthole. Secretly, I wished it was his fucken thick dick feeding my hungry hole. I guess somebody up there likes me cause right after my temp check, my pervy doc did a reach around and started sucking my already hard dick. I thought that would be my treat of the visit but he surprised me by turning me around and nailing my ass with his rock solid cock. I could feel every inch stretching and filling my ass up. It felt like he could fuck for hours..I mean he fucken nailed me so long and so hard that I didn't want it to end! Now I know why some guys my age say older dudes REALLY know how to fuck!
