Kiki Cali walks in on her stepbrother who is struggling to start studying. She wants to help him out and give him a good tip to use before studying: rub one out. She wasn't going anywhere either, she needed to make sure her stepbrother was drained first so he can focus on his studies. What a great stepsister! She took off her shirt and bent her fat ass over to help him get in the mood. She then offers to jack him off and give him a sloppy blowjob. When that wasn't working, she let him fuck her fat juicy pussy. He was still struggling to nut so what does she do? Offer her tight little asshole, of course! That definitely did the trick, even I'm ready to bust just by looking at her ass. With her legs spread wide open, there's no way her stepbrother can last long. Or does he?
