I sometimes think a lot about scenarios like this. Maybe I should start writing stories, haha

I also really like if the bottom is wearing chastity, and the top has some cock ring that both keeps him fully hard at all times and also preventing orgasm, so they're both constantly very horny and frustrated. The testing chamber could also be filled with aphrodisiac gas. โš ๏ธ๐Ÿฅด

I'm really into the concept of two guys wearing rubber test dummy suits and are forced to experiment with various sex positions and such, as lots of cameras monitor and analyze their every movement.

I need a rubber mascot to rub my dick between their big squeaky mitts and make me finish all over their pathetic rubber face. ๐Ÿฅด

For sure! It may not always be the most apparent during the actual play, but that's how it should be. It's also important with good aftercare after scenes like that.

That seems a quite excessive..
I don't know about the ADHD/autism thing. I thought it was more about struggling to express them and struggling to relate to other's feelings, rather than about feeling them. I would advice you to speak with someone who knows more, especially if you think it's serious.

I'm no therapist, but I don't think there's anything necessarily wrong with not really showing emotions. Some people are more expressive than others. But if you don't really feel them that sounds more serious.
Like I usually don't show negative emotions at all. But I definitely feel them.

You know, when I say things like being a dom or even sadist, it's only really in the context of BDSM.
I'm actually quite emotional in real life.

Heheh~ I'll make you fill a jar, no stopping until either it's full or you pass out~ ๐Ÿฅ›๐Ÿ˜ˆ

So scared~
The wearer would be totally helpless to anything that might be done to them, especially when those locks are attached. What are they gonna do? Boop me?

Everyone deserves good friends to be able to rely on. Especially during hard times.

Yea, if only I had a cute guy around...

I hadn't thought too much about the cuffs before getting them, but they're great. I love the dark metal parts.

Now you're just asking to be tormented! I'll teach you a lesson of my own! ๐Ÿ’ข๐Ÿ’ข

Hehe, well... I definitely won't be going easy on you.
You'll be a whimpering mess by the time where done~ >:]

Heh, yeah. Your hands are pretty useless while wearing these~
I look forward to making someone else wear them and teasing them >:]

Yea, I wasn't sure if it would be included with mine, but luckily it was! I needed a pump so it was a great bonus! The bag is also pretty nice and I love the shackles.

Thanks, I'm happy with them! โœจ :D
I can recommend them. They're a bit difficult to use alone though, haha

They do! This color is actually custom. Perhaps that is why it took so long.
