Nerdy college girl Jessika Night is studying hard for her exams. Her horny stepbrother is watching and getting turned on. Even dressed in her usual frumpy clothes, he gets a good look at her round, full ass and it is just too much to resist. He takes out his cock and starts stroking it. Staring intently at sister's ass, he doesn't notice when his girlfriend Lana comes in. She sees him whacking his cock off and is shocked, but excited. Jessika still hasn't noticed what brother is doing so Lana sits on his lap and asks is he likes sister's ass. Turned on by how naughty it is, Lana starts sucking her boyfriend's big cock while he watches Jessika. He tries to stay quiet, but eventually lets out a load moan that catches sister's attention. Jessika turns around to see brother get a deep, sloppy blowjob. Lana makes a move on Jessika, helping the shy college girl out of her clothes. She is embarrassed at first with brother watching her, but seeing his cock throb makes her little pussy wet with anticipation. Lana brings her over for a closer look and helps guide Jessika's mouth to brother's cock. The kinky scene turns Lana on as she sees just how much her boyfriend's nerdy little girl loves sucking his balls. Remembering how he was staring at her ass, Lana positions Jessika on all fours and helps slip his meat into her from behind. Happy to share, but wanting some herself, Lana switches places and eats Jessika's freshly-fucked pussy while getting pounded. He can't believe his good fortunate as the two sexy babes ride his dick until it explodes into his girlfriend's mouth. She spits it onto Jessika's tongue and the girls savor every drop. He can't believe his luck. He already has a hot kinky girlfriend and now how he has a horny, bit-assed sister to be his private fuck toy.
