It's a particularly warm day as Kevin and I lounge on the couch. The sun shines through the window next to the couch, its warmth counteracting the cool breeze of the air conditioning. He's snuggled with a pillow on his chest as he watches a TV show on the projector and drinks from a glass of whiskey and ginger ale. His firm legs are across my lap, and he periodically moves his right foot into my hand so that I can rub it. The skin is smooth, soft, and warm as I knead the muscles underneath and tweak his toes. He gets a lopsided grin when I do that. It's adorable.
I'm only somewhat paying attention to the show- Ok, fine, I'm not paying attention at all. I glance at him and am distracted by light hair as my gaze moves up his thighs. The hair thickens slightly as it disappears into the edge of his red and white kiddy briefs. The outline of his cock in the thin jersey fabric is enough to make my breath catch, its plump form distending the pouch that barely contains it. He's usually in a diaper when we're home alone, but he was feeling hot today and opted for his favorite briefs. They're my favorite, too. Big surprise, I know. His foreskin covers most of the head of his cock, but I can still see where the edge of his glans ridges the soft fabric. His balls are neatly tucked in above and behind his cock, resting gently against his thighs. Underneath, I can see where the fabric has pulled taught between the bubbled cheeks of his ass, giving a tantalizing view of his crevice. The top of his briefs give way to a gently curved belly. Just pudgy enough to be cute. The light treasure trail of hair emerging from his briefs runs smoothly up to his belly button. It's calling my name.
I gently rub the inside of his thigh with my left hand, moving in small circles with the tips of my fingers. Kevin gives a slight sigh of satisfaction and scoots his butt further down the couch, closer to me. This puts my hand on his hip, with the backs of my knuckles resting against his warm cock. He's asexual, and sometimes nervous about physical contact, but he's always friskier when he's been drinking. I consider taking my hand away. ...Nah.
I start to move my fingers gently back and forth, rubbing slightly against his shaft. I feel a slight shift, and it almost seems like the shaft firms a bit. Is he... getting turned on?
"Mmm," he says lightly, and swats gently at my hand. Foiled.
I move my hand to rest on the top of his briefs, against the slight swell of his tummy. I play lightly with his trail of hair, swirling the short, fine hairs with the tip of my middle finger. I start to follow the trail up his stomach to his belly button, and I poke my finger into the hole. He giggles softly and snuggles closer to me again. Interesting. I run my fingers around the edge of his belly button, dancing their tips softly on his skin, just close enough to cause a light tickle. He giggles again and squirms, the pillow falling off his chest and onto the floor. He's still looking at the screen, but I can tell I've got his attention as he sneaks a look out of the corner of his eye. As he looks away, I repeat the tickle around his belly button, eliciting another giggle. I move my other hand onto his belly and start to tickle with both hands. He's giggling and squirming, his legs rubbing on mine as he moves. His calve rubs across my tumescent cock, and I feel blood beginning to pulse into it as a tickle of pleasure runs through my abdomen.
I start to tickle him in earnest, and he's laughing now, grabbing short breaths when he can. I pull myself from under his legs and move slightly on top of him as I continue running my fingers across his belly and sides, letting them dance lightly over his skin. He's laughing harder now, and having trouble catching breaths. His legs have started to squirm together, and I move to sit on top of him. My bare ass, hugged by my white and blue jockstrap, rests against his briefs, the tip of his cock tucked right between the firm globes of my ass.
"Haha, I really—Ahaha," Kevin says, trying to grab words between the peals of laughter that make his belly jiggle and his eyes water. His hands are above his head, and he's gripping the arm of the couch. "Ahaha, No, seriously—haha—have to—haha," he manages, as I continue relentlessly, a devilish smile plastered on my face. I can feel him pressing his legs together under me, and he tries to move one of his hands under me, his fingers brushing the tip of my cock, which is almost fully hard and has begun to tent the fabric of my jockstrap. I grab his hand with one of mine and move it back above his head. My cock twitches as he submits to my firm grip. I start to tickle him harder with my free hand, leaning across him slightly now, and leaning into his stomach. I feel his legs tense up as I press on him, and it occurs to me that he's probably been trying to tell me that he has to pee. I make a point to lean harder on his abdomen, and I feel my cock go completely rigid, forcing my jockstrap away from my body.
"You're pressing—Hahaha," (here his other hand jumps down and tries to work under me to his cock) "—Seriously—Haha—OH," he says, a breathless, laughing gasp escaping his mouth as his moist eyes go wide. He continues to laugh as I tickle him, but I feel his legs shudder slightly under me. I can tell he's losing control of himself. I feel the fabric between my ass go wet and warm as Kevin gasps out, "Haha—Andrew! I can't—aaahaha—I'm wetting!" I can feel the wetness spreading quickly across the front of his kiddy briefs as pee jets out of his cock, soaking my ass and the bottom of my balls as it runs down between us. My cock is pulsing in my jock, rock hard and sticking out of the top of the waistband. I'm so close to cumming that I can feel my balls pulsing slightly, my breathing is shallow, and my head feels light. There are waves of pleasure pulsing through my cock as I feel Kevin's warm pee saturating his cute undies as he wets himself uncontrollably.
I stop tickling him and let his hand go, but he doesn't move it. I look down into his wet eyes and realize that the tears coming out of his eyes aren't entirely from laughter anymore. His face is flushed with embarrassment, and he's breathing hard as the pee stops flowing from his slit.
He scooches out from under me and stands up, facing me. "You... Y-you didn't stop," he says almost accusingly. "I had to pee and I couldn't hold it." My heart breaks a little, but I'm still hard as fuck. Is his embarrassment turning me on?
I stand up, just inches from him, and put my hand on the side of his face, rubbing the tears from under his right eye with my thumb. "Hey! It's ok, sweetie. You're totally fine. It was my fault." I lean down, my lips inches from his. He isn't usually into kissing, but maybe this will be different. I hear his breathing catch slightly, and his eyes flutter shut as I look at him. He suddenly wraps his arms around my neck and presses his face into my shoulder, his tears wetting my skin. I wrap my arms around him, enveloping him. "Shh-sh-sh. It's ok. I'm here. I don't mind at all that you wet yourself," I say soothingly. "That's what the plastic under the couch cushions is for." I pet the back of his hair lightly with my hand.
He nuzzles me softly and says, "I just wanted to be a big boy today." My cock is pressed tight against his soft belly and, though I've backed down from orgasm, it is HARD. There's no way he can't feel it, but it doesn't seem to be making him uncomfortable.
He sighs softly, and I hear a slight hissing noise. I feel splashing on my feet and realize that he's peeing himself again. "Go ahead, Kevin. Let the rest out." The warm liquid wets the carpet under him. I can clean it later. I take one hand from around him and move it between us, placing my hand directly over his pissing cock. I can feel the spot where his slit leaks pee through the pouch, and it's the hottest thing I've ever felt in my life. It only lasts a couple of seconds, but I'm back to being close again; my cock feels like an iron rod, but somehow still molten hot. I feel the pee stop, his bladder empty, and as it does, I can feel his shaft firming and elongating, the head swelling undeniably. He is definitely getting turned on.
He reaches an arm down and moves my hand off his growing penis, placing it instead on the round, firm bubble of his ass. I pull back a bit and he looks up at me, his eyes still moist. I lean slowly down, and place an exploratory kiss on his lips. They're soft. I pull his lower lip between my lips as I pull back. "Ok?" I ask. I know this isn't usually his thing.
