A party when I was young

When i was young i went to to a birthday party somewhere in London with my parents. It was a family type party (not my family) and i was put to bed in an upstairs room as the party went on quite late. I woke up to find a man just like this standing over me. He was wanking like this guy and I realised he had pulled the covers back and had pulled my trousers down to my knees. He said 'shhhhhhh' and being an obedient boy I stayed silent. I looked up and watched him jerking off for what seemed like ages. He was stroking my thighs but not touching my cock. He was breathing heavy and he called me 'slut' just before his cock erupted just like the guy in this video. I felt wet splats on my chest and legs as he drained every last bit of cum from his balls. I remember him pulling his trousers on quickly and telling me not to tell anyone or I'd be in big trouble. I never told anyone about this til years later. This video is almost like someone filmed that incident. I am so hard right now. I always wonder how many other boys he did this to ??
