The stranger on the other side of the wall grunts in pleasure as their throbbing member is expertly sucked, the wet warmth enveloping them as they push deeper. The cocksucker eagerly gags on the massive shaft, saliva dripping down their chin, their own crotch growing wet with desire. The anonymous encounter intensifies as both parties chase their release, the only sounds echoing in the small space are wet slurps and ragged breaths.
