porcelain tub

Porcelain Tub. The rarest of all female asses that utterly confuses men of all races and religions. Like a porcelain tub it is very large, very hard, and very smooth. It is also known for its ability to stand up to a lot of abuse (durable) and retain heat similar to a porcelain tub. Female porcelain tubs have been known to induce psychosis especially in african-american or latino men.
