My First 'Assist'

My previous story (Show Off) related to my favorite way to stroke it. This story while at the same shop is prior to my current fetish of dressing up as a bitch slut & stroking it in front of whoever will watch (I have had some guys walkout after giving me a disgusted look). Anyhow I entered with the intent of buying a cock ring and heading home but when I was looking around I noticed the guy behind the counter was watching me closely. He was a big black guy, obviously gay, (or at the least bi)and when I'd picked out a 1-7/8" steel cock & balls ring, then got in line I couldn't help but notice his hands, they were huge! So I pay for the toy and the whole time he's making small talk...then with my change I get a slip, thinking it is the receipt I shove it in my pocket and leave, giving him one last look as I go. When I get in my truck I take out my change to throw in the ashtray and find this hand written slip from him saying how he would like to see me naked and suck my balls!

At first I thought what the f*#k but then I remembered his hands and my shaved cock & balls started tingling. Well I shut off the engine and head back in and give him a smile & wink as I buy tokens for the movie booths. I went back and found a booth and dropped some coins in and surprise---there is a interratial gay movie on with a big black guy on his knees sucking off this young white "twinkie". I left this on & dropped my pants as the booth door opens slightly. As I finish taking my pants off completely I see the counter guy watching me, the only thing he says is the store is empty and then gets on his knees with a sort of pleading look so as I stroke my cock I make my way over to him, teasing him a little,asking what did he want. he simply leaned forward and sucked my whole ball sack and both balls into his mouth as his big hands covered both ass checks, rubbing and pulling them apart while looking at my hard on. I immediately start jacking using long strokes. The feeling was incredible... I've never had both balls sucked at the same time! I quickly peaked and moaned that I was cumming & he just sucked for all he was worth while I shot cum all over the top of his head & face. I gave him my shirt tail to wipe off with then as we were exchanging numbers a customer came in so we split up and regrettably I haven't seen him since. That was an incredable assist to jacking and I often get off just thinking of his hands massaging my ass while sucking my balls. I've tried to duplicate it but haven't found anyone that can suck in both balls without choking yet!
