Snort. LOL@Susie. Sometimes you're too much but that was funny. It's kind of the same way here. I think nearly everything in one's house could be used in sex play or as a cat toy. One way or another, some pussy is going to be happy.
Greeneyedmate4u, great suggestions for the newbie.
Wooden spoons are divine. I had my pussy and nipples smacked with one today and loved it. Also fabulous for bottoms, of course. I also have a large wooden bath brush that has some bite to it and the other side is loofah for scrubbing plus little rubber nodes for massaging. The wooden side could be used first to spank the bottom, then the loofah side to scratch a sensitive red bottom. Paint stir-sticks also work.
Let's see, a man's house. Hmm, surely you have metal clamps around for something. Those can be used on nipples and other tender bits. And you can attach most anything to them (hello, duct tape) to add weight to go with the pinching pain. A leather belt can be used solo, as well as with a partner, for whipping as well as binding. A switch from a nearby tree, a fly-swatter, a ping pong paddle... The substances mentioned for irritation in the anus may also be used in the urethra in you're into that. Letting the edible items sit in warm oil may infuse enough power in them so you don't need the item itself but the essence of it. Saturate a cotton swab with it for insertion in the urethra - only an inch at the most. Or a saturated cotton ball in the anus.
My mom used to have artificial wax-coated plastic grapes with holes where they attached to the "stem.". As kids, we would suck on the grapes and eventually would squeeze one and it would stick to our tongues. It was a weird sensation and slightly painful. I'm sure there is something with a hole in it that can be squeezed and attached to your nipples or balls, some sort of suction cup thing. A wire brush used for cleaning car parts or whatever can be scraped on the skin.
A friend of mine made spreader bars using pvc pipe with holes drilled into it, a couple of leather belts and um, something to attach the belts to the pipes but I forgot what it was.
I'm exhausted and have to get some rest but I'll try to post more ideas when my brain is functioning again.
Meanwhile, there is a book or website called BDSM on a budget. Do a search for that and see what you come up with.
Have fun! Happy kinking!
