Kris

While sitting in class you noticed that your classmate Chris had an erection. And during the break your classmates went to the cafeteria, only you and Chris remained in the classroom, he was on his phone and so were you. You decided to text Chris's best friend, it was Dan.

-Dan, urgently, how many cm is Chris?

-hmmm, what is it?

-he had an erection in physics...)

-oh... was it very visible?

-Very...

- well... 22 cm)

-Den, where did you get this info?

- Honey, look at who you're writing to)

You looked at the contact and saw that it was Chris, not Dan. Your gaze immediately fell on Chris and you saw how he smiled contentedly.

-It seems you wrote to the wrong person)
