SWELL makes sex so much better…for both partners! SWELL is a cocksheath that jacks off the guy while he pumps…the inside shaft is loaded with nubs and more “headroom” than any other sheath, more room to feel the stroking—the rubbery soft silicone blend stretches and strokes. SWELL gives as well, the ultra smooth shaft feels slick and velvety—there’s no texture, it’s not veiny, there’s no flared head, it’s just a fluid polished thick pole. But…push all the way to the base and SWELL swells much thicker—the base is covered with raised rubbery nubs. Feels amazing! It’s all about the base: it’s wider than the shaft, thicker and wider to rub and stretch with that extra thrust when you want to go deep—the contrast of the smooth shaft to the thick textured base will cause moans. Extra soft plus+silicone™ TPR/silicone blend with stretch to fit any size guy, SWELL adds girth and length to you…and makes the base of your shaft extra meaty and thick.
