In the midst of a family movie night, John and Sophia can't help but steal glances at each other, their desire for each other growing with every laugh. As Shrek's voice booms, so does their heartbeats. Sophia, her pussy throbbing, whispers, "Sisters gotta cum too, John." John, already hard, agrees. They sneak away, John's 18cm cock leading the way. Sophia, a first-timer, gasps as John's thickness fills her, but she's eager to learn, riding him until he creams inside her, marking her as his.
