Laya and Riley are forced to stay at home and take care of their teen stepbrothers Parker and Jimmy. The girls really want to go to a party and hook up with these really cute guys from school one night but, with nothing else to do, they start doing sexy stuff together, something their stepbrothers overhear and observe from behind the door. Later on, Laya and Riley are determined to go to the party, so they ask their stepbrothers to cover for them. All horned up by the secret private show, Parker and Jimmy agree to cover for them in exchange for a favor. The two boys never had sex before, so they want a little help from their favorite stepsisters. The girls agree but only if they get blindfolded. As Laya and Riley suck their stepbrothers' cock, things get steamier and steamier, resulting in a very hot foursome.
