Pissed of the wrong girl.

I am now 23m married and this is also my wife’s account so thank her for being cool enough to letting me tell this story. At the time I was 17 and I had just started dating a girl from the grade beneath me and we hadn’t done anything yet. I was still a virgin and she said she was aswell. We went to a party in a friends barn in the middle of a field and we were having fun dancing and I said I had to go use the washroom she said she also had too but there wasn’t one. We went behind the barn and behind some trees and bush’s and she just pulled her pants down and squatted and peed I was a little taken a back and also a little turned on but she stood up readjusted and looked at me she said “Don’t you have to pee”? I explained that this was a little awkward for me because no girl had seen my Dick and definitely hadn’t seen me pee she said no worries and turned around I pulled my Dick out and just as I started to pee she came up behind me and grabbed my Dick. I instantly became rock hard and she just widely controlled my Stream and laughed. After this was over she poured some of her vodka drink on the tip of my Dick and washed my Dick and my sack with it. At this point virgin me was already ready to bust but then she gave me what I know now to be a very inexperienced blowjob but at the time it was enough, after about 5 mins of teeth on cock and only really getting anything out of her foundling my balls she finally seemed to figured things out. I pulled my head out of my forskin brushed it on her lips I softly pushed my cock in the back of her mouth and lightly into her throat I then cam a huge massive premature load right into this poor girls throat. She immediately pulled back coughed and gagged through the words “fuck you you disgusting asshole”. Exactly as she started to say this the last little bit of my load sprayed out and splashed her hair forehead and eye. She gave me that pissed of white girl pouty look sobbed and then something changed in her, I saw her look at my balls and I went to cover them and pull up my pants but as I stood up from picking up my pants from my ankles she punched me as hard as she could muster right in the balls, she caught me so hard my balls bounced of my ass and came back with force, I crouched over in agonizing pain and she left the party apparently loudly telling her friends what had happened. I can back to my fiends who found it hilarious and half sore balls for a whole week. I want to be clear that I didn’t mean for that to happen I wouldn’t have done that on purpose and I genuinely felt bad for the girl but her reaction was a little bit over board.
