I covered it with a rag and the panties in front of me were uneven...I inserted it just like that.

She slipped on the rag and fell down........
Her pussy feels too good...!
My hips are moving on their own... I can't stop!

--I'm on cleaning duty, and I have to compete with two girls in my class by wiping down a super long hallway.
I thought I was so unmotivated... but then I saw the girl in front of me with her underpants in full view...?
I want to see them more closely! I was suddenly motivated!
But I was so excited that my penis fell out!
And when the girl in front of him braked suddenly, he got a little too excited... and inserted his penis into her pants!
There's no way I can stand it! She's getting fucked so hard and so slippery!
She's so hot and horny, she can't stop fucking!
