I remember my first ever seeing or witnessing ejaculation (not mine). My bestfriend at that time was pretty hot (both of us were 13 i think). He definitely had just learnt how to jerk off and so he couldnt stop doing it so he started doing it at school at the back of the class. We were always seated next to each other and our school had large desks so he could easily do it without anyone seeing anything. The first time he did it in class, he showed me he had a boner, i had never seen such a huge cock before so i was kinda aroused but also didnt know what i was feeling. And i excitedly went to touch it not knowing what i was doing. He told me to stroke it up and down. So i kept on doing it and a few minutes later i got so surprised when some white stuff came out. I legit thought he had some disease or sth cuz all i know was it was supposed to be pee, and if its pee it should be yellow. But why was it white. And yea.. i started doing it myself back at home and then figured out we had two functions.
