Thug Made Me Suck His Dick

I am openly bi and i live in the hood. There are alot of thugs all ages and one night when i was coming back from my friends house, this one thug who was 17, 6 foot 3 black teen from the area ran up on me at night with a gun and wanted to rob me, i was walking through the park so it was dark. I knew it was a BB gun but when he took my wallet, he made me suck his dick too with the bb gun to my head. ive sucked dick before but never a bbc and it was fucking huge. like not exaggerating but like 9 inches and super thick. he fucked my throat hard and came all over me and said not to tell anyone or he would kill me. when he left i just got so horny with all the cum on me i ended up jerking off in the middle of the field licking his cum.
