The door creaks open, and in steps a second man, Chong, his eyes widening in surprise and lust at the scene unfolding. Nam, the woman, notices him but doesn't stop, instead, she beckons him closer with her free hand. Chong approaches, his own cock straining against his pants as he watches Nam's skilled mouth at work. He joins in, his hands caressing her body, teasing her nipples, as she takes turns pleasuring both men in a taboo threesome.
