Popular two-tier bed series. The younger sister tries to stifle her moans while getting excited from sex with a man, hoping her older sister won't notice, but her gasps escape and the bed shakes. The quiet older sister, noticing this, pretends to be asleep while getting aroused by the sounds of her sister's moans, becoming wet between her legs. After finishing with the younger sister, the man reaches out to the feigning-sleep older sister's body, ready to enjoy a "sister bowl"…
