Is I’ve told in other posts here, it started with some innocent doctor play with a friend of mine when we where kids. (5 or 6).
At first we used pens/pencils outside our sweatpants moving on to clench the object between our buttcheeks with our underwear still in place.
After a while we just put the pen between the buttcheeks with no actual penetration.
We then snatched our respective families thermometers; one glass with pearshaped bulb and one digital.
I remember beeing on my stomach when he pushed it in.
I dont think it was the feeling of a unlubed thermometer that got me hooked at first, more the feeling of beeing exposed, vulnerable and ”taken care of”.
Ofcourse, as we got older we both had erections and found it erotic playing with the thermometers.
We took polaroids and filmed so that we could sit at home alone and watch.
I remember the cold sensation when the bulb penetrated my butthole.
It felt really great.
And I could almost dry-come when I took his temp in different positions. ?
