Get the dirty kirby mug.
When your dog watches you have sex for only 12 seconds because you are old and waits for you to get up so he can put his red rocket where it belongs and finishes what you couldn't.
Good thing that ho couldn't tell that dirty kirby was in the bed.

Get the Dirty Kirby mug.
When a pink party ballon is used as a condom for anal sex. When you are finished take the ballon off while keeping it in the persons butt and then proceed to inflate it. Now without tying it off try and pull it out and once it is free let it fly and dodge the goo filling.
Me and this chick did the dirty Kirby last night, and she was pretty disgusted with the outcome.
