I start to tease him and play with it. I take my hands off and just run my tongue from the bottom of his balls to the ridge of the head where it is extremely sensitive. I do this a few times just so I can see his dick bouncing. Just looking at his cock swing up and down was enough for me at that point. By now I can tell his balls are full of cum and I want him to release it all in my mouth so I grab his cock and start sucking the head, mmh, mmh, mmh, mmh! Going deeper with every suck I start to feel his cock head throbbing on the back of my tongue. I deep throat it and keep it there gently going back and forth while I start playing with his balls again. I feel his sack getting tight so I slowly pull his cock out of my throat and start jerking him off. Mmm, this is some good dick I think to myself and begin sucking some more, mmh, mmh, mmh. My mouth is loose and wet and I have a nice rhythm going so I decide to stroke him with the same rhythm. I feel him press harder against the wall as I'm licking, and sucking, and stroking and just then he says, "Oh shit I'm about to cum." I give him what I call the trinity, 1) I grab his balls and start massaging with one hand, 2) the other hand is stroking that saliva lubed shaft, 3) I am sucking the cock head simultaneously. I open my mouth and put the cock head on my tongue and start jerking him with two hands. Knowing he is point five seconds from exploding, I suck the head a few times to give him that push he needs. And just like that, I was stroking out load after load of warm cock cum across my tongue and down my throat. I start sucking it again letting the cum drip on his cock while I was still stroking it, just to give him that added satisfaction. He was moaning something wicked and rubbing that wall like he was in love with it. He was cumming hard and a lot and I was proud and at the same time horny as ever!
I hurried up and got to the lobby before him so there would be no speculation. He came out smiling and gave me a hand slap saying, "Dude, we defiantly have to come back. One of the best blowjobs I have ever had. That shit was so good I kind of want to meet the chick back there. But she is probably some old fat lady so I guess its better this way (laughing)." Then I say, "Or some guy". He didn't think twice about it and said, "I know right, either way we are coming back."
Me already having a cock full of cum, the fact that it might not bother him if a guy gives him a blowjob, takes me over the edge. So I had to go home and jerk off. On the way back and ever since that day I have been wanting to tell him it was me that gave him one of his best blowjobs ever...but it's our kinky secret (the reader and I).
