I've been caught a couple times by the SIL, female friends and strange in a hostel!

I wasnt <caught> but a few years ago the hotel maid walked in whilst I was naked on the bed enjoying a good wank. I had EarPods on whilst watching interracial porn on my laptop - the maid probably told her colleagues about my small cock

I object to anyone claiming you can be <caught> wanking unless you are breaking the law. Using that word strongly indicates we should be ashamed and guilty about masturbation.
