Back That Ass Up — Auto Mega Masturbator by Pipedream

Back That Ass Up User Guide & Play Styles

Advanced solo sessions: dialing in suction and vibration rhythm

The Back That Ass Up is designed for men who have moved past entry-level strokers and want precision control over their solo wellness routine. With 6 suction modes running independently of the 12 vibrating modes, you can layer a tight pulsing suction pattern over a rolling vibration rhythm — or hit them in sequence to build intensity. The 10.8″ life-size stroker accommodates full-length stroke technique, and the dual-motor system keeps sensation consistent across the entire channel. Use water-based lubricant for optimal feel inside the pleasure tunnels. Keep sessions private and easy with the USB-recharged unit ready at your bedside.

Getting the most from the life-size stroker format

At 9.8″ wide, the Back That Ass Up delivers the heft and grip of a female sex dolls torso format without the storage footprint of a full doll. The white finish and life-size dimensions make it one of the more immersive life-size female sex dolls alternatives in the best male masturbator category. Position it flat or angled depending on your preferred stroke angle — the width provides natural stability. After your session, the material care is straightforward: rinse the internal channel thoroughly, pat dry, and store out of direct sunlight.
