Pre-Christmas Wank

A week before Christmas, I was on my way home from Christmas shopping when it started to rain. So I had to find shelter in the library near my house. As I went in, I saw a guy I sometimes see around the area smoking outside. He turned and saw me and we just acknowledged each other's presence and I went in. The rain was still pouring heavily even after the two hours I spent reading. By this time I was pretty hungry and went outside to see if the rain had at least become small enough for me to hurry home. It was still a moderate downpour so I just stood outside for a minute to sign in exasperation. Again, I saw the same guy standing outside smoking again. I thought it was weird cos this guy doesn't seem like the sort who even knows what a book looks like, let alone spend up to two hours at a library. But I just figured he was also waiting out the rain. I've never spoken to the guy before, only seen him from time to time around the area. Whenever I'm on my way to the train station, I would stop to pat and play with the neighborhood cat and sometimes I would see him sitting on a nearby bench smoking, sometimes alone, sometimes with friends or his girlfriend. We've never spoken but I'm sure he recognizes me the same way I recognize him. He looks to be in his mid to late twenties with dyed blond hair, usually wearing an army singlet and shorts. A typical picture of a Singaporean delinquent. However, he looks pretty fit with somewhat toned muscles and a pretty boy face which probably means he's popular with girls. I've never thought about him an any sexual way except be jealous of his looks and body. Standing outside, the humid air in contrast to the cold air conditioning of the library made the blood rush to my dick and I started to get hard. Seeing as the rain doesn't seem to be stopping, I went back inside to the restroom. I went to a cubicle intending to have a slow, satisfying masturbation session. I was leaning against the cubicle wall, dick in hand and slowly stroking. Picturing other people masturbating turns me on a lot and I was imagining what the guy outside would be like when he is masturbating. I was oblivious to the other people coming in and out of the restroom until I felt something tap on my foot. I looked down to see a hand holding an iPhone opened to the memo/notes app. I bent down to read it. It said "Hey bro, I know you're mast in there. I am also. Want to JO together?" I typed back a yes and he suggested I come over to his stall since it has more room. I gathered up my stuff and went over to see him already leaning against the wall and stroking slowly. He gave one of those "cool guy" smiles which I returned and slid my jeans and underwear down to grasp my semi hardon. He whispered "Relax bro, I'm straight. But it's more fun to mast together." I just smiled back and continued stroking. We were standing shoulder to shoulder facing the toilet, a little while ago I was imagining what he looked like jerking off and now I get to do it side by side with him. He is uncut, sliding his foreskin to completely cover his dick head and then back down along his shaft. Both of us were breathing pretty heavily. After about five minutes of pumping our dicks, he put his hand on my shoulder and squeezed, and I saw him shoot several drops of cum out into the toilet noiselessly. I sped up my pumping and within the next ten seconds I also grabbed on to this shoulder and shot my cum out. We were both stroking slowly, squeezing the last few drops of cum out as we calmed down from our orgasms. Wordlessly, he passed a few sheets of tissue to me and we both wiped ourselves clean. He told me to leave first and he'll wait a few minutes before leaving also, but before I left, he gave a friendly slap on my butt and a smile before waving bye. The rain had stopped by then and I made my way home. Seeing as we both live around the area, it's likely I'll see him again.
