I am looking for ideas for selfies my subs to send me. It needs to be quick and easy things, as well as safe, sane and consensual. Humiliating, degrading, painful, uncomfortable, sexy or funny work best.
Some examples: - paint toenails - wear a white thong and pee in it - write embarrassing words all over your body with permanent marker - clothespins/ wax on genitals - put on cock cage and ride the biggest dildo you have - I order a sex toy or clothes, you have to use/ wear it as soon as you pick it up - try on women's lingerie, send pic from inside the dressing room - go to the super market and buy something embarrassing (e.g. cucumber and vaseline / ask for the smallest condoms they have) - shave all of your body hair
Because of covid-19 I practice social distancing and only meet my two primary partners. So I give my other subs assignments they can do from home etc, and they have to send me live photo proof that they completed the assignment. 
I'm sure you lovely people can come up with some interesting suggestions!
Something me and my girlfriend have been into is public games such as, we go into a pub and she visits the toilet when she comes back she tells me that she no longer has knickers on sometimes sits there so I can see to get me turned on. Then tells me she has slipped her knickers into my coat pocket and that I’m to go into the toilet to change I must go and put hers on. While I’m in there changing she will message me telling me she wants proof that I’m wearing them so I have to take a picture in the toilet and send it to her knowing she will open it in public. Then I go back and join her still wearing her underwear. We often do the public toilet pictures to when she has me in my Chasity cage and we are with others to enhance the chance of being caught and adding more edge to it.
Other things you could do is get him to wear a collar under his clothes so you both know he is in it. One with a word on it like slave and get him to show it off to you or take selfie of it in public when he feels he can. If you want to step the humiliation up more have a collar you can put the lead on but that’s in your pocket till you choose or when you get back and you can attach it and do a photo shoot. If more risky do that in public where nobody is, so you can get the one picture and then let him back off the lead.
In house photos could be him on his knees sucking on your strap on or doing forfeits for him to be able to get his pleasure then when you reward him talk about using the pictures as blackmail.
muscleman_rocky Thank you so much for your comments and ideas!
The first one sounds great but isn't possible in my/ our case since we do not meet in person. Obviously they can't take a photo showing their underwear when in a pub, café etc, and I can't trust them to not change to their regular underwear after sending a ''proof'' pic when in the toilet.
I love the idea of wearing a collar in public. I live in Sweden and even during summer it can be cold enough to comfortably wear a scarf on some days, so they can easily hide the collar until they are somewhere they feel comfortable to reveal it and take a photo.
About the last idea, I could totally ask them to suck on a dildo (maybe after they've used it). Last week one of my subs had to wear lipstick and deepthroat a cucumber. That was fun! 
Always been a fan of making people spank themselves until there's a visible mark. Pictures of their own cum on their fane or tongue usually does thr trick too if they're not in chastity without you around
Have them cover their crotch with food or deserts while giving themselves pleasure . I thought something I did once was a great visual , my wife loved it . I covered my hairless crotch with an even layer of chocolate sauce and shot loads of cum across it . Contrast between the two were excellent . Then another picture of me scooping up some chocolate and cum and licking it off my fingers .
What about wearing obvious nipple pasties/tassels under regular clothes while doing day to day stuff. There is potential for it to be noticed by people (particularly under a standard white shirt)
Oooh, I love this idea!
Two of my online slaves have a darker complexion and I’ve had them take photos and videos while pouring milk all over their body. The results were stunning and extremely hot.
Thick syrup or sauce could definitely work! They also come in lots of flavours and colors, and I can tell them to add sprinkles if I want it to look extra cute.
Furthermore, I know from personal experience that it’s quite painful if one is not clean-shaved, haha!
That’s a big yes! I’ve had one of my slaves to wear nipple clamps with a chain under a white T-shirt and go shopping for women’s lingerie.
For another assignment, he wore a bra, went grocery shopping and bought only a banana, vaseline and condoms. He absolutely loved it!
I guess you could also do asking them to send a nude selfie (with or without additional props) in a public bathroom?
The door is locked so shouldn’t be possible to offend strangers, but still uncomfortable for being nude it that kind of space!
