Under the guise of 'cleaning', the siblings delve into a sordid game of hide and seek, their bodies entwined in the cramped bathroom. The brother, harder than ever, can't resist the temptation of his sister's tight ass. He spreads her cheeks, revealing her pink hole, and spits on it, making her gasp. He rubs the saliva in, his thumb pressing against her asshole, making it clench and unclench. She pushes back, wanting more, and he obliges, slipping a finger in, then two, stretching her ass while she rides his hand, her pussy dripping with excitement.
