In the dimly lit room, Denis Klein's thick, veiny uncut cock throbs, waiting for David's touch. David, kneeling, takes it in his hand, stroking it gently before licking the head, tasting the salty pre-cum. He swallows it whole, gagging slightly as it hits the back of his throat. Denis' hips buck, fucking David's face as he moans in pleasure. David's hand works Denis' balls, rolling them gently, as he quickens his pace, eager to feel Denis' hot cum in his mouth.
