After graduation, Kai challenges the girls to prove they took their tits out. There's a bit of teasing about Kai wanting to fuck his stepsister, but Sera and Jade both pop those boobies out for Kai to enjoy. When they finish making out for Kai's benefit and see how big his boner is, they go right for a double blowjob.
Sera takes the first turn sliding down onto Kai's hardon and riding him in cowgirl. Once Jade has had a sample of her own, Sera gets on her knees for Kai to do her in doggy while Jade masturbates and gets her nipples sucked by Sera. Sliding forward on the couch, Jade spreads her thighs for Kai to dive nice and deep and make her squeal before he pulls out for Sera to direct his cum shot all over Jade's landing strip.
