Drunk Friend

Last year while I was 17 myself my best friend had been drinking at his house and my friend had got really drunk (I don’t like feeling dizzy so didn’t have much).
He was lying on his bedroom carpet totally out of it an was sick luckily i had put his waste bin under his head to catch it all.
I couldn’t leave him like that so decided to ring my parents and arranged to stop there the night .
I undressed down to my undies and thought I better undress the drunken friend before me.
When i had got him down to his undies I don’t know why I did it but i just couldn’t help myself,
I pulled his undies forward to take a look a his dick I already knew he had a big dick but seeing it close up made it look huge even though it was soft and limp.
I started playing with myself just starring at his big soft dick he didn’t have a clue what was going on.
I was so turned on and positioned myself to cum on his dick and balls (i shot so much over them).
When i was finished I pulled his undies back over his now cum covered dick and put a blanket over him and went to sleep.
The next morning i was woken up by his moaning and swearing,
He said he had been sick in his bin and had a wet dream in the night and was soaked in spunk.
Little did he know it was my cum he was covered in.
