Super Booty Erection Test

I brought Olivia Cheeks in to perform in a study about the possibility of a guy cuddling with a girl without getting an erection. The only caveat is, we'll both be lying together completely naked. I oil up those amazing buns she has before I spooned beside her. I tried my best to stay soft while my dick was pressed against her big ass, but I stood zero chance of keeping it down. Since her booty was so oiled up, my slipped right between her cheeks. She let me slide between them for a few strokes, just to get it out of my system. I mounted on top of her with her legs closed. I'm not sure what to call this position, maybe a straddling missionary thighjob? Of course, I was a rock solid at this point so we changed it into something a little different. I lifted her legs to see if I could stay soft in missionary while her legs were on my shoulders. There was no way I could restrain myself from pushing it deep inside her. Since this was not supposed to happen, we changed into cowgirl and tried again. I made a very serious attempt to keep my dick from getting hard this time. Feeling Olivia's huge badonk bouncing on me made me uncontrollably hard. I couldn't subdue the urge to grab her by the waist and slam my cock up into her. I completely failed the staying soft test, but I wanted to try one more thing with her. She bent over, and I rubbed my dick in the middle of her ass. The way her cheeks jiggle while I jerk off against them is a site you have to see. After poking the head of my cock in and out of her asshole, I needed to feel that pussy one more time before I let her go. I'm surprised she let me put it in during this ass fetish only video. I pushed it deep so I can feel every sensation while inside of her. Her shiny oiled twerking ass made me bust a huge nut on her backside. I haven't seen an ass like this in a long time, and I'm sure you'll love the view of these cheeks.
