With the house to themselves, the horny pair decides to make the most of their alone time. They've barely started when they hear footsteps approaching. Quickly, they hide, but it's too late. Mama walks in, finding them entwined in a compromising position. 'I can't believe this!' she exclaims, shaking her head in disgust. They try to explain, to apologize, but she's having none of it. 'You're both grounded!' she declares, leaving them to stew in their shared shame and horniness.
