So I'm going through old vids, looking for stuff to add to my montage I'm planning to release soon and I found this cumshot experiment that I thought you guys would find amusing. The idea was my erection slips out of my shorts and then my shorts sort of "jerk me off". I have string attacked to the inside and then my friend Charlotte was pulling the string. Sadly it wasn't enough stimulation to make me cum but I hope to revisit this one eventually and maybe modify it so it works better. What do you guys think?
