The big dick brother serves his stepsister....

Gabbie Carter was preparing to go to a concert and needed to change clothes. Sam was waiting for her to finish so they could pick up his sister and go to the concert together. He goes upstairs to check on Gabbie but sees her changing clothes so he sneaks a peek. She notices but then calls him to help her decide which bra looks best. She finally confessed that she had always wanted to have him inside her!
