Most Japanese lotion is very thick in nature which can sometimes ruin the masturbation experience. ToysHeart Onatsuyu Juicy Lotion is specifically designed for use with masturbation sleeve. The viscosity and stickiness has been balanced to help you better experience every bump, groove, and nub on your sleeve. ToysHeart also addressed many flaws other lotions have in their design by making ToysHeart Onatsuyu Juicy Lotion stay moist much longer, so you don’t have to re-lotion as often(if ever at all!) while also making it easy to wipe off. Do you and your sleeve a favor and try ToysHeart’s Onatsuyu Juicy Lotion.
