INVADER is Oxballs first open ended cocksheath that is built to fuck as long and hard as you want. The shape gradually adds more thickness to your shaft so the middle is the fattest and it narrows down at the tip so you get all the feel at the head--and the hole you plow gets more stimulation from your fatter humpy shaft.

Oxballs invented the modern cocksheath by morphing our original cocksling to a sheath creating the first sheath that really stay on no matter how hard you play. INVADER is that good and more*our first open-ended sheath with wavy ripples on the shaft. and texture inside. so everyone gets max stimulation. Made of PLUS SILICONE*. our slick soft silicone & stretchy TPR blend.
