What's the biggest or oddest thing you've ever had up your ass?
Mine's an 18 inch dildo.

Back in 1975 I was in Weippe,ID one night, it was all loggers in this hotel bar and no women. These guys wanted to drink and fight and that was it.

So I went to bed horny as hell. No dildos, just my finger but as I was finger my ass and jacking off I saw the leg of a end table. As I looked at it I wondered if it came off and sure enough it did.

So washed it good and I slipped a condom on the tapered leg that was about 18" long by 1" on the bottom and 3" at the top. I did have some hand cream and I inserted it and took about 12" of it. When I came I shook the place, I'm sure the loggers were wondering what the hell was taking place above their head.

A cucumber about 3/4 in probably about 10"and thick.
18" bj i think is to the point of damage

Only took about half of it bioap.

Wasn't odd or huge but very erotic
I was spending the night at my friends house while the rest of his family was out of town
I was 19 at the time
we had drank a lot and he was passed out and I went snooping around his house and into his parents bedroom
I found some playgirl magazines under the mattress
I looked through all of them and started looking in the drawers of the dresser and found a vibrator
I took it to the bathroom with me fantasizing about my friends mom and dad using it
I had my pants down with a rock hard dick kind of stroking a little and started easing the vibrator into my ass
The only thing that had ever been there before was my finger .... so it took a little time to get it in
I had about half of the 7 " in my ass and it felt incredible .... I eased in about 2 more inches working it in and out very slowly
I had almost the whole vibrator in my ass and just let go of it kinda savoring the sensation while I rubbed my hard dick
In about 2 minutes I shot off all over the bathroom floor
