I masutbated last night and my fanny started twitching!

I like it when my wifes fanny twitches.

I raped this homeless woman last night and she had a twitching vagina!

When a man gets sexually aroused and 'horny' so he masturbates and when he cums he lets his seaman fly into the fish tank, killing the fish, but resolving his sexual fustration.
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!
