I stuck a can of deodorant up an ex girlfriends asshole in a tent at a motorcycle rally. She loved it, kept it in her ass whilst we fucked - naturally we wasted as well. She liked it so much became a regular occurrence.
Then with the wife, had a wine bottle 3/4 of the way up her pussy and another time a cone shaped shampoo bottle up her asshole in the shower.
I believe one of her recent playmates had a beer bottle in her pussy whilst fucking her asshole, or so they have told me 😀
