Carlosmelo12's peaceful slumber was shattered by the passionate cries of his friend's lover, her pleasure echoing through the thin walls of their shared apartment. Her moans, raw and uninhibited, painted a vivid picture in Carlos' mind's eye as he imagined her writhing beneath her partner, her body tensing and releasing in waves as she chased her orgasm. The sounds of their flesh meeting, the wet, slippery noises of her arousal, and the occasional whispered words of encouragement from her lover all combined to create an auditory symphony that left Carlos both aroused and envious.
