Masturbation kit with a suction pump, 3 silicone erection rings and a jelly Senso pussy sleeve. Sample lube included.

Pumps can extend length while using, but the question is, will the penis return to original size after using? Unfortunately we do not have that answer and can not guarantee or be responsible for any results.
