Fish-Tank Wank

I had a wank last night and didn't want a huge mess all over the carpet so I did it in the fish tank!

Shit, i appear to have killed my fish.

Fish-Tank Wank's are the best!

Fish Tank(ing)

When a female has a smelly pussy, and traps you under the bed sheets.. much like the common Dutch Oven.

The hilarity of my boyfriend's dutch oven was quickly dissolved when I instead spread my legs and the dreadful smell of pussy entraped him in a tank of my vaginal fishyness. Boom, fish tank(ing).
