I'm looking for ideas for improvising toys and equipment, and/or advice on what sorts of things aren't safe when homemade? My male friend is very interested in exploring submission, bondage, humiliation, and pain. So far we've been using under the bed restraints and a strap on. He's indicated he'd also like to be blindfolded and gagged and spanked and whipped and wear women's clothes and in general have me be rougher and cause more pain. So I guess my question is can I just gag him with a tshirt and beat him with a belt, or is it a better idea to go shopping for items meant for those purposes?
