Hopping in bed just does it for me.
After several long hours of working, whether it be at school or at my job, I would always look forward to the evening hours.
When everyone went to bed, I would read a few good sex stories and take off my shirt, take in a whiff of my armpits (which I believe had pheromones in high levels, it always made me hornier for whatever reason), and threw off my pants then my underwear.
I revealed my then near-six inch cock, normally covered by a bush of hair. I think this hair kept some heavy pheromones too, because if I got a whiff of my cock smell I would get even more turned on.
I'd replay the sex stories in my mind (at this time I was a virgin, and still am, as I'm waiting for my wife!) while I jacked off fairly quickly. Even at the speed I went, which was considerably fast, I still took between seven and twelve minutes to finish. I lasted at least more than thirty minutes when I humped by bed.
At this point of the story I was thinking about, a sister is straddled on top of her brother, just about to make him burst. As soon as he unleashed his cum onto her, I tightened my hand almost into a fist, and pumped at least twelve huge ropes of creamy, viscous cum all over my chest and my face. I never cared for the taste of cum, even if it was my own, because if I ate it all it would leave a really weird tingling sensation in my throat and esophagus... but tonight was a special night. I knew what I had to do.
