I was threatened with having it taken rectally once because I wouldn't stay still during an oral one. It wouldn't have been much punishment as I'd been doing it for a long time already.
I recall inserting the thermometer rectally on myself when I was very young. It would give me an erection even then.
When I was about 5 or 6, woke up one AM and my mom wasn't in the house. I
went to the bathroom, retreived the rectal
thermometer and returned to
my bedroom. I laid on my stomach, pulled down my pj's, and proceeded to
insert and remove
it in my tiny bottom. I must have played too long
though, because when I got up and left my room to return it, there was
mom. She said 'do you have a fever?' I was shocked, and begged her not
to tell dad. She told me if I liked things in my bottom so well then the
next time she caught me she would give me a quart enema, I'd never had one so was scared, although I would fantasize about it for years
I even tried to get caught with the thermometer a few times when I was near adolescence just so I could
get the forced enema. I positioned myself nude, in a knee chest position, bottom pointing towards the half open door, inserting the thermometer as my mom passed my room. Somehow she didn't see it.
