In the dimly lit attic, siblings Leo and Ava, both in their late teens, find themselves alone and curious. Ava, with her long, wavy hair and round, full breasts, teases Leo, her older brother, by changing in front of him. Leo, with his strong jawline and muscular body, can't help but stare at Ava's tight, round ass and perky tits. Ava catches him looking and, instead of being upset, she smirks, liking the attention. She sits on his lap, feeling his hardness grow. They kiss, tentatively at first, then with increasing passion. Leo's hands explore Ava's body, cupping her breasts, pinching her nipples. Ava grinds on his lap, her pussy getting wetter by the second. They're about to take it further when their mother's voice echoes through the house, breaking the spell.
