A more advanced, yet still wonderfully user friendly pump strategically created to work very noticeable plumping, erection enhancing, nerve ending awakening magic, the Precision Pump collections' Intermediate easily, effectively and very pleasurably draws blood into the tool in question, increasing sensation while creating a fuller appearance and a harder erection. Aside from the after-effects, the very act of using with this great pump is intensely enjoyable, a supple, hypoallergenic, snugly clinging silicone donut sleeve placed at the opening wraps tightly around the head, creating an airtight fit and strong, stimulating suction. The naturally warming, temperature receptive nature of silicone will come in particularly handy in this case, contributing to enjoyment, especially when combined with a good water based lube. To get started, simply slip the sleeve and sturdy cylinder comfortably over the penis and squeeze the over-sized, trigger-style style pump handle to increase suction within the chamber, which is transparent and thoughtfully measured in increments for progress visualization. Should you need it, a quick release valve on top of the pump cylinder instantly dissolves the hold.
