I give a rectal

We often slept several of us cousins in a bed at my aunts farm in the summer. Sometimes I slip up behind a boy in the bed (18 years old or so) when he asleep and slip his undies down. I slip my fat finger in his tight virgin butthole and stretch it for him and his first time getting a rectal exam first prostate exam. I sneak lard in there keep it under the bed. Sometimes they cry 😭, but if they go wake up my aunt they get the paddle!
