I (33 years old, slightly overweight but still decently muscular) am hot and sweaty after a fierce workout. I walk into the shower room of the gym. With a towel wrapped around my waist, I see you (an older man) entering the locker room as well. We had several brief conversations in the weight room waiting for several pieces of equipment to become available. Your slight and seemingly incidental touches drove me crazy with confusion and wonder, and want! I nod at you going towards the shower, you nod back, the sweat from your workout has seeped through your mesh workout shirt and running shorts.
Unwrapping my towel before entering the shower stall, I look back to see if anyone is watching. Having recently gained weight, I'm self conscious and comfortable being nude in public. I turn on the hot water and the let the steam rise around me. I take the shampoo and lather it around my decent sized cock and balls, rinsing the sweat of an epic workout off of me. I reach for the soap bar when I hear a knock at the shower door. Its you. I crack the door open and the steam that misted any vision of my body in a protective haze eeked through the crack. You tell me that all the showers are taken and if I would mind sharing with him, you look away to draw my attention away from an obvious look down at my soapy cock. I stutter nervously, not knowing exactly what to say. I am attracted to your stature, your posture, your brazenness, but I know so little of man and man interaction. While I am internalizing all of these things, you have walked in, said thanks for understanding, and closed the door of the shower.
You reach around me and turn the hot water back on. Your hand falls down towards my plump, but muscular rear end, letting it graze along the bottom curve. My cock springs to attention! "Woah there partner," you say, cocking your head getting a good glimpse of my penis. You turn around, untying your towel and hanging it up in the stall. Your firm lean ass beckons to me. "I really am glad that you are cool with this, you sem like a nice guy from the weight room and the other showers were taken," you say as you turn around. The shower is tight. Your body motion pits us next to each other, full contact between our sides. "Besides," you continue, " if two guys can't shower together, what is this country coming to?" I nod, completely entranced by the moment. You reach behind me for another bar of soap, your tool rubbing against my leg, mid-thigh.
It can't be that big I think to myself, it just can't be. I step forward to allow you to get a better access to the soap bin, you move forward and the Louisville Slugger you call a dick is softly entrenched between my ass cheeks. The tickling feeling between my legs, livens my spirits and other aspects of my anatomy.
