In the privacy of his backyard, a curious soul experiments with his body's limits, using a thick glass bottle as a makeshift dildo. He slips off his panties, leaving them striped around his thighs, and brings the bottle to his ass. The glass is cool, sending shivers down his spine as he presses it against his tight hole. With a deep inhale, he pushes, feeling the bottle stretch him wide, filling him completely. He fucks himself slowly, feeling every inch of the glass sliding in and out, his moans growing louder. The thought of neighbors watching only heightens his pleasure, as he pushes the bottle deeper, his asshole gape inviting and lewd.
