Fuk Tool Sheath and Ball Stretcher
Transform your cock into a big black Fuk Tool!
The Fuck Tool firmly grips your package and enhances your erection while encasing it in thick stretchy thermoplastic rubber. The rubber will dull the sensations enough to help you go longer. Meanwhile your partner gets a marginally thicker dick with firmer veins and contours in his ass. You can slam his ass until you explode, filling the sheath with your own cum.
