OP here. If you really wanna know, he soaked them so they were slippery and put them in one at a time. He's got an inflation fetish and is really into butt stuff. The only reason he tells me all this stuff is because I'm one of the only people in his life that he can be totally TMI with. I'm trying to gently push him into talking about it more with his girlfriend, who's into some of the same things, and less with me. I have a strong stomach but I'm just sick of only ever talking about butt stuff! ?
