Eric tossed and turned, unable to stop thinking about his last call of the night. He'd seen a lot of weird things in his time as an EMT, but something about the naked, burly man passed out on the sidewalk had pushed the encounter to the top of the list. A tenant in one of the squat apartment buildings lining the street had called it in, saying they saw the h...

Fixing the straights

by cdbaby on Dec 28, 2016

You wake up and prepare for your day, unaware that this would be the last day you would be considered straight. You shower as you did every morning and felt the water's warm touch as it cascaded over your skin. You could stay here forever if you could. But you need to start your day and the hot water would run out before long. You wash your hair, then the re...

Despite his impressive body, the fit young man still looked awkward as he stood in his boxer briefs in front of the mirrors that reflected him from all sides.

Push out. Relax. Tighten. Relax. Derek was working out, lifting weights, making his muscles even tighter and sexier. He was lying down on the bench, lifting weights, listening to workout music. He put the bar down and sat up, wiping away his sweat. Suddenly, a hand clamped down on his mouth, preventing him from yelling out. Derek's assailant beat his abdomen...
