A gorgeous girl named Serena Santos has prepared everything in order to work out with her classmate. The girl has been dreaming of a guy's penis for a long time, and today she is going to seduce him with her breasts, but our heroine's sister Vanessa Sky decides to prevent her from doing this. She wants to annoy her sister, so she wedges into their learning process, hinting that the male can also choose her. At one point she climbs under the table, pulls out a guy's dick and starts sucking it. This is noticed by Serena, who pushes her sister away and continues to suck a hard dick herself. The guy decides that his penis is enough for two, and fucks each of the girls in turn, bringing them to the cherished orgasm.
