"Dude. You don't have to hide it."
Matt pointed down at the bulge in my shorts. My cock was an iron bar and I had been trying to keep it tucked away since the girls had first started taking their tops off. I took my hand away and suddenly felt self-conscious knowing that he was looking at the tent my cock was making of my shorts.
"I've got one too, man," Matt said.
As if I hadn't noticed. The bulge in Matt's own shorts was enormous. He hadn't tried to adjust himself or tuck it back even once. His cock stood out so hard it actually left a visible space between his bare, rippling abs and the elastic band of his bathing suit.
"Yeah," I said, blushing. I hurried by him and up the stairs back into the house. I tried to tuck my cock back again before I realized it wasn't going to work. Fuck it, I thought.
"How could you not have a boner after that?" Matt said when the door closed behind us. He pointed a thumb over his shoulder back in the direction of the pool, where the girls were waiting for their refills. "We just spent the last half hour staring at four sets of titties."
I opened the refrigerator and pulled out the drink mix and the ice. When I turned around, I saw Matt leaning against the counter, smiling at me. His huge bulge hadn't gone anywhere. He had broad shoulders and a smooth, muscled chest. I found myself following the lines of his pecs and abs down to the gap between the rim of his shorts and the lower part of his stomach.
"Do you want to see it?" Matt asked. He hooked his thumbs under the band of his shorts and pulled them down just slightly. The movement revealed a glimpse of his pubic hair and pushed his cock a bit down and out. It dawned on me that I did want to see it. I wanted to rush over to him and grab it.
Instead, I turned around and worked on making a batch of daiquiris. I knew my face was bright red with embarrassment, and something in me didn't want Matt staring at the bulge in my shorts. If anything, my cock had only gotten harder since we came inside. I could feel Matt's eyes on my back.
I turned around.
"Let me see it," I said.
Matt smiled. "You first," he dared. "Let me see that cock."
My heart pounded. My hands were shaking. I wanted to show him. I wanted him to see my cock in all of its erect glory. And I wanted to see his. Hands trembling, I hooked my thumbs inside the waistband of my swimming shorts and pulled them down to my knees. My cock sprang up and pointed straight at Matt.
"That's a nice, big cock," Matt said.
"Now you," I said. My voice was hoarse and shaking. I leaned back against the counter, cock in the air and watched Matt pull his shorts down and drop them to his ankles. His cock was somehow bigger than I had imagined. The massive shaft stood straight out, topped with a swollen purple bulb of a head.
"That is," I stuttered. "That is a huge cock."
"Yours is pretty big too, though," Matt said. "It's nice and hard."
Matt stepped close to me and grabbed my rigid prick. I gasped as he worked his hand up and down my shaft. Pleasure soared through me. I reached to him and closed my fingers around his enormous member.
