Meanwhile the girls dorky stepbrothers Axel and Elias are talking about locker room stuff on the couch. They are absolutely convinced that they have bigger dicks than their classmates and they are bragging about it. Serena and Ava overhear the boys conversation and come up with an idea what if they used their stepbrothers as nude models Though a bit creeped out about the idea everyones on board so the guys show the ladies their dongs. However Axel and Elias are a bit shy so it is up to the girls to make those penises become fully fledged boners. The art assignment becomes a horny fuck fest as Ava and Serena realize how tasty their stepbros dicks are eager to test the boys pussy pounding abilities up next.
