When Nick Strokes' girlfriend Penelope Kay comes in on them, they are in the middle of fucking his stepsister Molly Little. After Penelope storms out, Molly advises Nick to pursue her. Penelope made it clear that she wanted Nick to discuss, not actually carry out, his stepfamily fantasy of fucking Molly when they sat down to work things out. Molly advises that they should talk about it as she reaches out to slide her palm down Penelope's thigh. Molly accepts Penelope's offer to watch her make out with Nick since she thinks it would be cute. After the girls continue chatting, Molly pulls Nick's hardon out and asks Penelope to play with it. The females eventually start flirting in the lead-up to a trio. Molly finds herself in the center, with Nick tucked between her thighs and her lips caressing Penelope's protruding breasts. Then, as she finishes Molly, Penelope gives her a pussy pounding fit fit for a dog. As she assists Molly in getting into Nick's lap, Penelope gets increasingly heated and masturbates in front of Molly. When it's her turn to have Nick's stiffie again, she lies on her back with Molly riding her tongue and loves him giving her a big D-pucker. After working together one final time to get Nick off, the girls share his cum shot and decide they should do this again.
