Two guys are having fun playing video games and talking about Wonder Woman and other geeky stuff. Their stepsisters come into the room to talk to them. They are surprised that they do not have Valentine’s dates. The girls decide to take things into their own hands. They start the full makeover of their stepbrothers. All four of them like how things are going. They look more handsome, and their stepsisters ask them if they ever kissed a girl. Of course the girls have to teach their nerdy stepbrothers how to kiss. These nerdy dudes are never going to get laid if they don’t start making an active effort to put themselves out there. After a few days, the girls wait for their stepbrothers all dressed up. They are wearing amazing and provocative dresses. Their big booties are a piece of work before everyone’s Valentine’s date. The girls don’t want their brothers to be virgins forever, and they suggest a sis swap! Are these teen girls really about to fuck in front of their own stepbrothers? Both of the boys have huge wanglers, and the girls can not believe how great a lesson they are having. The girls are gagging so much on those two huge cocks. Naturally, both girls take off their panties and easily set on the boys’ dicks. Both of them start bouncing and begging for harder fucking. Both of them are perfect cowgirls. During the variations of cowgirl positions, these two naked girls are trying to teach the boys all that they know. Now the missionary position is at large. Two naked girls are moaning harder and harder while their brothers are drilling them. They can not get enough of the boys. During the doggy style, the girls are exchanging the experience of fucking each others’ stepbrothers. Now the boys switch, and it becomes even spicier. Everyone knows how fucked up the situation is, but they also feel incredible. When the guys can no longer hold their loads, they bust their nuts on their stepsisters’ faces, who then share a cum glazed Valentine’s Day kiss.
