The girls decide to come up with a way to measure his cock. Lili tries to apologize, saying she didn't mean to make him uncomfortable and that she loves him and his dick just the way they are. When Juan doesn't immediately hug her back, Lili asks if he wants her to prove it. Overriding Juan's weak objections, Lili pops his hardon out and begins sucking it. Ivi is watching from the doorway and tries to call Lili on her choices by claiming she was joking about sucking Juan's dick. Lili rolls onto her back and peels off her panties to say she wants to see if it will fit in her pussy, too. At first, Ivi is put off by watching the stepsiblings to at it, but she quickly realizes that she finds it really hot.
