Thinking Of Erotic Stuffs

Have you people ever had those pervy or erotic thoughts going on at the back of your mind while conversing?
As for me;I just can't help but imagine weird scenarios' of people doing ecchi things, while I pretend to listen to my cousin nag about her bf or when my mom asks me to do stuffs.

P.S: I'm not in the scene, only men are doing each other!!!
( I think it's severe addiction to yaoi/bl )
