Samantha, a bored housewife, decides to test her anal boundaries. She nervously prepares herself, lubricating her bottom, then sits on a large dilator. As she pushes it inside herself, her husband, Mark, walks in seeing the toy on the bed. Confused, he starts to question her actions. Samantha, ashamed, tells him the truth. Surprisingly, Mark becomes aroused and proposes to be the first to penetrate her tight hole. They both grow increasingly excited as Mark slowly inserts his cock. The pain triggers pleasure as Samantha's anal walls clench around his shaft. With each thrust, she feels more full and satisfied. Their moans and gasps escalate before culminating in a shared orgasm, their bodies trembling with pleasure.
