The ERECTION ASSISTANT Adjustable Hollow Strap-On for Heightened Stimulation from Nasstoys is an 8.5-inch hollow strap-on that enhances performance and intimacy. Features an adjustable harness that fits waist sizes 29" to 59" and delivers a realistic feel with additional stimulation through its unique hollow cavity design.
The hollow cavity lets you slip inside while the 8.5-inch extension does the work. You feel the grip and pressure while delivering more length and girth than you could alone. The adjustable straps distribute pressure evenly, so you stay comfortable even during marathon sessions. Pair it with silicone-based lubricant for the smoothest experience possible.

Real experience:
I tried the ERECTION ASSISTANT after months of hesitation, and the first thing that hit me was how secure the harness felt. No slipping, no adjusting mid-session. The hollow chamber gripped me perfectly while I controlled every thrust with confidence I hadn't felt in years.
The moment I realized I could feel everything through the silicone while delivering more than I ever could naturally - that changed everything. My confidence shot through the roof, and the intensity of staying connected while extending my reach was incredible beyond words.
