Skinny twink jerking off to teacher’s nude pic in bathroom

My professor of physical education in college is a very sexy huk, whom I have seen naked many times. He does not know it but I have also several pics of him, that I jerk off to many times.
Yesterday, when I got a free period, I went to the teacher’s bathroom and began jerking off there thinking about my sir.

I looked at his nude and looked at every inch of his body and his cock imagining it to be inside my mouth and hole. In the end, I cummed inside a sink and then ate it.
