The summer of my 18th year, after graduating from high school, I had gotten used to having my bedroom to myself, when my older brother moved back in to share the room with me. He had moved out a couple years before, but eventually lost his job and ran out of money, so at age 20 he came back home to "re-group". We were the only two males in a house full of girls, and since there weren't enough bedrooms to go around, we naturally had to share. Kris and I didn't have much in common, other than having each been circumcised as baby boys, but as we reached adulthood, even our penises weren't very similar. Also, we each had a propensity to leave the toilet seat up after using the bathroom. While Kris was interested in partying and girls, I was more interested in other guys . . . a fact that I kept as a deep dark secret, especially from my older bro.
One hot Friday night soon after he moved back home, he came in late, reeking of beer and cheap cigars. I was the only person still up, and I asked, "Where've you been?"
"Pat's bachelor party" he mumbled as he stripped down to his briefs, climbed onto his bunk, and fell asleep (or passed out--I'm not sure which). While I listened to Kris' breathing level out to a deep, rhythmic pattern indicating sleep, I was entertaining bold, wild thoughts concerning my "options".
I finally decided "it's now or never" so I turned off my reading light, stood next to the top bunk, and watched my brother sleeping calmly. Fortunately, he was sleeping on his back, and once my eyes adjusted to the darkness, I could see the bulge in the front of his Jockey Shorts .. the target of my desire. I called his name a couple of times ... and then gently pinched his arm ... no doubt about it, he was asleep. I boldly (but gently) placed my hand over his crotch and felt the banked heat of his maleness. I very lightly rubbed and squeezed his equipment (through the fabric), and soon had Kris popping a boner.
