Teacher’s Passionate Final Performance

“Let’s see if we can improve them.”
She put the panties on one of the hooks, then put off her jeans and panties, too, so we both were naked down from the crotch now. My heart sank. Can’t someone clean them with a high-pressure cleaner?”
“Seems some people love strange things!”
“Wait, some people are turned on by water sports, some need the harder stuff!”
“I wouldn’t dare to walk around like that!”
“Now who’s the one who crapped in, the shorty or his lil’ bitch?”
“Don’t know, but boys usually don’t do this things, it has to be the nasty dirty girlie.”
“Hey, you owe me a tenner! Press your hand against my butt and rub it around a bit, that’s all I ask of you.”
I sighed and did as told – I laid my hand flat on the bulge of shit, pressed against it, and started to rub around lightly.
