Sissy's eyes widen as Tony's colossal cock springs free, throbbing and ready. Tony, smirking at Sissy's naivety, grips his shaft, pumping it slowly. Sissy, drawn like a moth to a flame, inches closer, her hand reaching out to tentatively touch Tony's massive length. Tony guides her, teaching her how to stroke his enormous cock, his grunts of pleasure spurring Sissy on. Their amateur exploration turns heated, Tony's big dick promising untold pleasures as Sissy's curiosity turns into eager anticipation.
