In this custom ordered video I play the role of a teacher teaching my class about how I give blowjobs. The most important part of my technique is making sure the guy is taped to the chair so he can't move, halfway through the video I also put tape over his mouth.. I give you, one of my students, jerk off instruction throughout the video while I explain to what I'm doing and why. I also put tape over your mouth before I get the guy close to cumming. Finally I use my hand to finish him off while he squirms in the chair unable to move or make any noise because of the tape!
