Well, the other night, I really wanted some serious anal stimulation, but I had thrown away some of my smaller shampoo bottles,a nd didn't really have anything of a similar smaller size (they were those hotel shampoo bottles, pretty perfect size for such things). So... I had to make due with one of my body spray bottles, which is pretty damn thick, but not impossibly thick... Still though, I really wasn't sure if I could get something that size up there, since it's been quite a while since I really tried to get something that size in my ass... Took me a good while, slowly worked my way up to it with my fingers, finally got four fingers in, and felt I was pretty much as ready as I would be... Took that bottle all the way up to the nozzle. Best cum I've had in months.
