The following day, I woke up with a boner and had given it a few loose strokes before I remembered that I didn't need to do that anymore; I had an on-call cocksucker now.
"Can you swing by this morning?" I texted Tyler.
It was a few minutes before he replied, and I wondered if he'd actually been serious about this arrangement, but he finally answered. "Yeah, I have class this morning but can come by after around 10:30?"
"Sounds good."
I played video games for a little while to distract myself, and before long there was a knock on my door. I paused the game to get up and answer. "Horny this morning?" said Tyler, as soon as I'd closed the door behind him.
"Yeah, I woke up with morning wood."
"Damn, being sucked off twice last night wasn't enough for you, huh?"
"Guess not. So you better get to work, cocksucker."
He dropped to his knees right there in the entryway, undid my pants, and had the head of my cock in his mouth in seconds. I groaned and gripped his hair as his tongue caressed it.
"Fuck yeah, bitch. You're my cocksucker, aren't you?" I thrust my cock all the way down his throat, then pulled it all the way out and pushed it back in a few times. He took it easily.
"Fuck yeah, I'm your cocksucker," he said, pulling off for a moment to answer me. "I love this huge fucking cock. I'm here to please this big dick."
I fucked his face for another minute or so, and when I pulled out he was panting for breath. I decided I wanted the blowjob to last for a decent amount of time, and I didn't want to just stand there, so I took his wrist and led him to the couch where he'd already sucked me several times. "Strip," I told him, and we both got naked as fast as our clothes would come off.
"Knees, bitch," I said, plopping down on the couch and grabbing my cock to wave it at him. He obeyed immediately and my cock was back in his mouth in seconds, as if he was optimizing for the minimum amount of time without dick between his lips.
I sighed and stroked his hair and told him what a good cocksucker he was and how good it felt to have him bobbing up and down on my big cock. After a while I lounged back on the couch with my hands behind my head and my legs wrapped around him.
He'd been improving at sucking cock faster than I'd thought possible, and it wasn't long before I was ready to cum. I'd intended to last longer, but what the hell.
"I'm gonna cum in your fucking slutty mouth," I told him.
He took his mouth off me for a moment to ask, "Should I slow down?"
"Nah, don't worry, you can keep sucking after and I'll give you a second load."
He gave me a grin shaded with relief before plunging back down on my cock, sucking furiously and stimulating the head of my cock with his tongue. "Oh, yeah, you're gonna make me cum. Fuck yeah, cocksucker, take my fucking load, fuck, fuck, fuck, fuck!"
I moaned and thrashed and pushed myself deep down Tyler's throat as I came, and I could feel his throat muscles gripping my cock and milking every drop of cum from it. As I came down, he slowed his sucking and I collapsed back against the couch, my cock still in his mouth. He continued to stimulate it until I finally couldn't take any more.
"Stop, stop stop stop," I said, laughing. "It's too sensitive."
