In the dimly lit room, Rod Fontana's muscular body tenses as he feels a stranger's eyes on him. Scene 4 of "Anal Witness" begins with Fontana's hand wrapped tightly around his own throbbing erection, stroking slowly. As he turns, he sees a figure in the shadows, their intentions clear. The stranger approaches, their hand reaching out to Fontana's ass, fingers probing his tight hole. Fontana's breath hitches as he feels the intrusion, his own hand moving faster on his cock. The stranger's fingers are soon replaced by a thick, pulsing dick, stretching Fontana's ass as they begin a fierce pounding, sending Fontana's own cock dripping with precum in response.
