His fellow onlookers gasp as his dick grows, hardening and lengthening within the pump's confines. The room fills with the sound of pumping and moaning, the air thick with the scent of pre-cum and sex. One by one, the other amateurs take their turns, each experiencing the intense pleasure of the penis pump, their untouched cocks swelling and leaking in response to the powerful suction.
