Lana walks into her bedroom to find her submissive boyfriend viewing another woman's ass on his cellphone. Lana is furious as she has such a voluptuous butt and takes offensive to this. Lana's subby boyfriend doesn't think it's a big deal at all which annoys Lana even further. When her subby boyfriend tries to initiate sex, that gives Lana the sadistic idea to dry hump him until he orgasms instead. Lana quickly straddles subby boyfriend while she grinds on top of his body. Then she straddles his face with her ass, squashing him at the same time. Subby boyfriend struggles underneath her big butt all while his erection grows harder. Subby boyfriend is used for Lana's entertainment as she enjoys coercing him to orgasm while she repeatedly bounces her pussy and butt up and down on his cock as she is in full control of her human hump toy. As she pins him down while covering his mouth with her hand, her human hump toy has no choice to cum on her thong.
