Do you want to master/slave rp with me? I can be the slave but you'll have to be aggressive. ;)

mashed potato ass

An older woman's ass that is rotund and full of cellulite dimples. When they sit down, the ass seems to squish and go all over the place, as if they were sitting on a pile of mashed potatoes.

My sixty-five year old teacher has a mashed potato ass. It is very distracting.
