Aww such a shy pup makes me want to put a collar and leash on you to drag you to the next sexstore. In part so you can have some actual toys, in part to watch you get flustered as I hand you increasingly larger dildos and plugs.

Also some suggestions:

Hot sauces and tiger balm are options for burning things, though, I'd avoid using them internally.

Ruber bands can be fun to snap against sensitive bits too.

Thumbtacks pushed through thin cardboard can make for fun inserts into underwear.

God I'd be such a brat as you drag me there, constantly whining and growling and trying to fight back. And the bigger toys you hand me the more I shake my head and look away, but one gentle brush against my groin and you can instantly tell I'm growing harder and harder with every toy you show me, my tdick straining more with every time I try to refuse.

I've tried rubber bands, but I always pull away on instinct, I need someone else to do this to me so I stay still. I don't have any hot sauces at home really(I'm autistic and basically eat 3 different(bland by most standards) foods year-round, none of which include any sauces at all) but I DO have Tiger Balm... Oh, my next pain session is going to be interesting. And the thumbtack idea, now that I'd like to try out! One time I got some wire and tried to wrap it around my tdick like a chastity cage, so it wouldn't get hard, before going to run errands for several times. It actually hurt in a super sexy way at some point when my poor little dick actually tried to grow but couldn't, but the cage soon slid off so it wasn't sadly very effective - I was aware of the metal against my dick the whole time though, and was practically dripping by the time I got back home.
