Angel Gostosa and Zerella Skies are planning to move out of their parents' houses and move in together. The girls are chatting about their lives together when Angel tells Zerella that she's been thinking about having kids. Zerella is okay with it, so they discuss who will donate sperm to their cause. Eventually Angel asks about Zerella's stepbrother, Oliver Faze.
Oliver is in his bedroom practicing guitar when the girls corner him. Zerella tells Oliver that Angel wants to have a baby and that they want him to be the donor. He pushes back a bit, but secretly he's stoked to fuck his stepsister and her lover. The girls are soon getting him in the proper headspace with a double BJ that involves lots of ball sucking.
Zarella goes for a reverse cowgirl stiffie ride that gets those little titties bouncing. Then she watches Angel do the same while she masturbates. Getting on her knees, Zarella eats Angel's snatch while Oliver does her in doggy. As soon as Zarella is cumming, the girls switch spots so they can experience each other's pleasure. Angel and Zarella get plenty of cum to play with as Oliver blows his load in Zarella's pussy for Angel to suck out, and then again in their mouths for a bonus treat to swap and enjoy.
