Renato plans a surprise party for his stepson, Alex Romero, with Billie Star as his piano teacher. Billie entices Alex into an intense relationship, leading to a fun threesome where Renato slurps Alex's schlong, resulting in obscene fucking, slobbering, and ass-to-mouth fellatio. The guys beat Billie's behinds and eventually close the deviant teacher's mouth by cumming in it.
