Masturbation fodder

The best way to masturbate is to run a scene through your head. That said, porn vids help with the imagination process. I call these masturbation fodder. My top ones are

1) Thinking of cuckolding my ex

2) Getting anal stimulation from a nurse

Etc

Can you list yours

Anything involving pee-playing (golden showers, wetting bikini underwear, desperation, etc). Also, bisexual MMF activities, including cuckolding threesomes. Mutual masturbation for MF, MM, FF couples. All of these would be average, amateur participants --- not actors!
