Didn't You Know?

An older ponytail woman stares in shock at her phone while a black cat reacts, as a short dark-haired girl and a light-haired boy have vigorous sex in a bedroom; the girl watches a phone during the act. After climax they are confronted by the apron-wearing woman in the living room. Flashbacks show the pair progressing from kissing and cuddling to stripping, oral sex, multi-position vaginal intercourse, internal ejaculation, and repeated intense orgasms, with the woman sometimes working at a nearby computer. The short black-bob girl and light-haired boy continue intense nude sex in multiple positions, including cowgirl and rear entry; she sweats and smiles while checking a phone, and he ejaculates inside her repeatedly. They climax smiling, and the ponytail woman then lies exhausted on the floor beside a laptop as the story ends.
