The thrill of the unknown pulses through her veins as she kneels before the wall, her eyes locked on the small, dark opening. She can feel the anticipation building, her pussy growing wetter by the second. The first cock pushes through the hole, thick and veined, ready for her talented mouth. She takes it in, her tongue swirling around the head before she slides down, taking it deep into her throat. The man on the other side groans, his pleasure echoing through the thin wall. She sucks hard, her cheeks hollowing out, until he can't hold back any longer, his hot cum shooting into the back of her throat. She swallows every drop, a satisfied smile playing on her lips as she waits for the next anonymous cock to claim her mouth.
