"Get on your knees," Alex said as he sat down on the couch.
The stern command fueled the fire that had sparked as I'd watched him saunter through the front door of our apartment wearing nothing but his running shorts. His skin was still flushed from the exertion of his run.
I cooked when I was anxious, and Alex went running. After we started fucking, Alex took up running as if he were training for a marathon. I could see the change in his body, in his calves and his ass, in the gradual disappearance of the soft layer that used to cushion his muscles. I couldn't say I didn't appreciate every tight, lithe, sinewy inch of him, but I wished he weren't so unsettled.
I knelt down between his spread thighs and buried my face in the musky crotch of his running shorts.
One thing we'd both found out about me was how much I liked being "forced" to suck his cock, eat out his ass, lick his armpits when he'd come home all sweaty and ripe, his skin glowing and his muscles still warm and pulsing.
I put one hand on his thigh and another on his balls as I tongued his hardening cock through his running shorts.
He grasped my hair in his fingers and pulled me off his cock.
"Take your shirt off, Jeff."
At times he could be incredibly loving and sweet. Other times, he could be incredibly dominant and domineering.
I wasn't sure which I liked better.
"Yes sir," I said, pulling my shirt over my head, gasping as he roughly twisted my nipples.
The first time I'd called him sir during sex had been more of a joke than anything- a natural but flippant response to a firm command. But it made his cock harder and sent shivers down my spine and the more I said it, the less silly it felt.
"Hands behind your back."
"Yes sir."
"Good boy. Tongue out."
I stuck my tongue out and looked up into his eyes as he pulled his cock out over the waistband of his running shorts.
He rubbed his cock head under my nose and across my cheeks, looking me in the eyes the whole time, before placing it on my tongue. I let it rest there, enjoying the musky, salty taste of him.
"You want my cock, Jeff?"
I didn't respond, just stared brazenly back at him, a slight grin tugging at the corners of my open lips, the lust in my eyes answering his question.
Alex looked magnificent, imperiously reclining on the couch, legs spread, his hairy, muscular chest rising and falling with his breath.
Licking his still slightly floppy dick with my hands behind my back was a bit of a tactical challenge. After letting me scrabble after it with my tongue for a minute or two, he held his quickly hardening cock just under the head and let me lick and suck on it like an ice cream cone. He was making breathy little moans and I could see his pelvis twitching from the effort of holding still while I serviced him.
There were times when I felt completely submissive under his forceful control, but there were times like this, when I felt powerful making him squirm. The ability to make him completely unhinged with lust was intoxicating. The heat of it built up inside me until I wanted to rut against him like a bitch in heat, wanted to coat him in my cum.
"Oh, Christ, Jeff. Use your hands, man."
I held his balls in one hand, and wrapped the other hand around his cock while I licked and sucked on the head. I sucked his cock as far deep into my mouth as I could and let him fuck my face.
Alex pulled me up onto the couch so that I was straddling him and pulled me into a kiss. I melted into him, into his strong arms wrapped around me, his mind-numbing kisses.
He stood up and pulled me to his bedroom.
Alex lay on his back and watched me through half-lidded eyes while I rolled the condom on him and lowered myself down, easing his cock inside me. The first moment of penetration still held that incredible, heady mixture of pain, pleasure, and anticipation. I raised and lowered myself on his cock slowly, adjusting to his size.
After a few minutes of letting me be in control, Alex rolled me on my back, held my legs out to the side, and started thrusting into me. Alex had clearly learned a few things from his slutty past. Or maybe it was just natural talent. Whatever it was, there was this wicked way he could roll his hips when he was fucking me, almost like they were detached from his torso, which looked unbelievably hot, and felt even hotter.
My legs were wrapped around his back, the muscles in his arms straining to hold up his heaving chest, and his hips rolling as his cock fluidly and relentlessly slid in and out of me. And then my legs were over his shoulders, his hands on my hips holding me still, nothing but his hips moving, pounding his cock into me. Every hard, hot, thick inch of it filling me up, making me moan and pant, my head rolling from side to side involuntarily as I felt the cum boiling up in my balls, on the brink of shooting.
Finally, I felt his hand wrap around me. He jerked me off with quick, firm strokes until I came, feeling his cock slamming into me while my asshole quivered and contracted around him. Alex pulled out, pulled of the condom, and shoved his dick down my throat. It only took a few forceful thrusts before he came.
Afterwards, he rolled up on his side, his back to me, curled in on himself. Sometimes after sex the two of us would stare at each other in wide-eyed, grinning amazement, laughing at the dumbest things and pinching and poking at each other. But sometimes, and I could never quite anticipate when, he'd get this weird look in his eyes, halfway between sorrow and remorse, and would shut me out completely. When he'd get like that, withdrawn and distant, I'd invariably feel a twinge of doubt and regret.
It's not like I didn't get a little withdrawn myself, especially when we first started fucking. After the initial euphoria of orgasm would wear off, this sense of uneasiness would start crawling up my spine.
So, maybe I pulled back slightly, but when Alex pulled away, he completely shut off. It was as if he put up an invisible wall between us. At first I tried acting normally, but he would get so weird, would ignore whatever I said to him and pull back from my touch, so I learned to give him his space. I'd fall asleep if I were tired, or take a shower and fool around in the kitchen until he'd re-emerge from whatever dark place he went to.

When Alex and I first met, back when I still thought I was straight but everyone else was already convinced I wasn't, I used to get hit on by guys a lot. Alex was probably the worst of them. He wouldn't take no for an answer. It was kind of annoying, but it was also kind of flattering. He was charming as hell and fucking gorgeous, and from what I could tell had his pick of boys on campus. If I'd even had half a clue that I would want to sleep with him, I definitely would have thought Alex was way the fuck out of my league.
