The U-Boat Driller Flesh is absolute pleasure for two with its 2 glans-like shafts on both sides and well-shaped veins. Penetrating and being deeply penetrated at the same time is certainly no problem here! Made of soft rubber of the best quality, odorless, non-toxic (plasticizer free) and very easy to clean with for example a little detergent. This anal dildo from Domestic Parner is resistant to any lubricant!
