Pumper Inflatable Hollow Strap-On

Master Series Inflatable Hollow Strap-On – 7" Size-Boost Cock Sheath & Harness
Turn your shaft into a throbbing, inflatable monster

Slip into this ultra-thin silicone hollow strap-on and watch your cock transform in real time. The Master Series Inflatable Hollow Strap-On lets you slide your dick (hard or soft) into the 7 inch sleeve, strap in, and start pumping – with every squeeze of the hand bulb, the shaft swells in girth up to a full 2 inches thick. It looks and feels like a real erection, only bigger, harder and completely under your control.

The stretchy waistband and ball strap keep everything locked in place, while the open rear leaves your ass free for double penetration games. Perfect for ED support, stamina training, size fantasies, or just putting on a show as you grow thicker mid-session.

✦ FAQs

✦ Will this work if I struggle to stay hard?
➤ Yes – the hollow design and inflatable outer mean you can keep giving deep, thick thrusts even if your erection softens.

✦ How big does it really feel?
➤ Fully inflated, the shaft reaches around 2 inches in diameter, giving a noticeably thicker, fuller sensation compared to a standard penis.

✦ Is it safe to fully inflate?
➤ Always inflate gradually and stay within you and your partner’s comfort zone. If anything feels too intense, simply press the valve to release air instantly.
