Ideas for long-distance punishment?

That would be very triggering, maybe the live would include another sub to send a message that "you can be replaced" while you are away..

Also, it can be irritating to watch your DOM turning into a SUB into someone else hands (and watching that live)..

I hope that helps your friend...

I think that mental BDSM could help a lot. Simple orders as: 10 minuts in front of the wall without any movement could be extremely exciting, intimate and creates strong link.

Just lie down on the beach for 8 hours without sun tan cream.

@*********nots I strongly think that submission must be by own desire, not by others desire or fear.
So… work on mental side in a good way developes trust, strenght and the referred desire. But always must be deserved, cause is the biggest gift that a person could receive from other.

Yes ... you cam-communicate regularly and ... surprise you have sex with you new friend(s) here, on livestream.

My little submissive went away on a business trip over the last few days and on her way home her flight got cancelled and had to rebook a later stop over. She is such a good girl I punished her by organizing a guy to go around meet her in an airport bar restaurant at Frankfurt and had her be a good little girl for him.
They had chatted online before so he wasn't a total stranger and I'm pretty sure she didn't think it was punishment as within 20 minutes of meeting him in the flesh for the first time I got a skype call with her on her knees in a car park toilet and his cock in her mouth. He fucked her so good and I'm now at the airport at home waiting to taste the fun my little sweetheart had when I give her a kiss to welcome her home
Sometimes your subs can make you proud of them, I think the dirty little slut liked her punishment

Ideas for long-distance punishment

I generally give instructions with drawings for her to do when she is there at the business trip or away for whatever.
[ I'm drawing them myself she gets additionally wet by looking at them after the reads 😉 ]
Not punishments really because she knows if she will not follow the instructions, do as I please , punishment will be here when she comes back. She makes sure she always leaves a little undone 😜
