Powersling Cock Sling Ball Stretcher Purple from Oxballs. Powersling is a limited edition cock sling modeled after Oxballs discontinued, best selling Nuttsling. It is made from their signature Flextpr so it is rubbery and squishy but still firm enough for some serious sack stretching action. The soft, flexible material and sling design grips your sweaty sack and shaft and pushes your package up and out for a bigger bulge. Powersling is perfect for filling out your favorite jockstrap or ass hugging gear. The extended base of the sling keeps your nuts pushed down and away from your body. It also feels awesome while you jerk or plow some sloppy hole. An inner ring in the stretcher grips your ball bag and keeps your boys from popping out. Original design copyright Oxballs.
