I tell you, “Stay away from me, son. It’s forbidden. It’s taboo.” And yet, holy shit, I want you. [Father/Son incest fantasy]

It’d been some time since I last touched you. I had my reasons for it. Not to get close to you again. You were my son. My own flesh and blood. And yet, a year ago, when you’d turned eighteen, you’d managed to make me believe that it was okay. That there was no harm done if you climbed into my bed at night and touched me…there.

And God, I hadn’t minded. Not one bit. But there was this nagging thought in the back of my head that I shouldn’t be doing this. I should be the one protecting you, not the one exploiting you. You were so young. So deliciously innocent and yet, Hell, so goddamn eager and fucking dirty. It blew my mind. Because you knew exactly what you wanted. Me.

*Daddy, Daddy, Daddy.*

I was your caretaker. Your father, your friend, your lover.

And I stood in the way of any other options. Because when you were with me, you weren’t with anyone else. I couldn’t…live with that. So I had set you free. Two months ago. And ever since that day, I’d made sure that you slept in your room (again) while I slept in mine, alone (again). It was hard. So many nights spent sleepless, staring at the ceiling, wondering if you were still awake. You were, and more often than not, you’d tried to seduce me again.

But no. I had to stay strong.

I’d been so young when I’d had you. Now I was almost forty. You were nineteen now, in college, doing well, making friends. Like tonight. Tonight you were out. You’d texted me that I shouldn’t wait up for you, so I didn’t. But I was still lying in bed, scrolling through my phone, thinking, restless… what if you met someone? What if that someone kissed you, touched you, took you home? My stomach turned. Fuck…I couldn’t even let that thought sink in. I’d set you free so you could do those things, and yet, they ate me up from the inside.

To calm my nerves, I turned to social media until I ended up in my photo app. I don’t know how I got there. Suddenly I was thumbing through videos and pictures you’d sent me. You laughing, wearing puppy ears, teasing me, a cheeky glint in your eyes. All…innocent. Except one. One picture was of you on your side, naked, thighs together, pulling your ass cheeks apart. No face in the picture. Just your ass on display and that perfect little hole.

Instantly, blood was redirected downward, to my groin, making my shaft thicken and grow within mere seconds. You’d taken that picture just for me. My perfect little boy. I shouldn’t have been slipping my fingers past the waistband of my briefs. And I definitely shouldn’t have started to stroke and bite back moans. But you weren’t home. You’d never know.

Breath short, balls heavy and full, moving with each upward pump. I was losing my fucking mind. Again. Blankets kicked off, toes digging into the sheets as I thrust up into my hand, breathless. I’d make such a mess once I blew my load, I knew that. *Fuck*…you were in charge of laundry and you’d wonder why I’d wash the sheets by myself…that wasn’t a good solution. It was gonna be a big load, I could feel it.

With my cock rigid, twitching, I reached over to the nightstand. Condom. Tried to rip the plastic open. Failed. Once, twice. Until finally, I slipped the thing out and rolled it down my rock hard shaft. What a fucking brilliant solution. I jerked off with my eyes shut, to see you, to feel you. It was so wrong, so forbidden. I’d told you not to get involved with me again and now here I was, getting involved with the fantasy of you.

Tension built so swiftly I could barely stop it from rising. Warmth pooling in my lower gut, muscles tight, lips parted. The memory of you. You had my eyes and your mother’s dark hair… I thought of the way you corrupted me on a daily basis, flirted with me, teased me, bent over the kitchen table to be fucked. To be bred. I thought of your hot insides, clenching, sucking me in…nothing could have prepared me for this. And nothing could compare. Certainly not the fucking condom. I could feel the hot tension gather at my spine, ready to burst forward…and then, it did. Holy shit, it did.

My vision blacked out, my back arched, and I gasped for air as though I was drowning. Pleasure spread like wildfire while my balls contracted, pumping out the big load I’d predicted. But there were no hot splashes on my skin. No thick jets of cum lacing my chest. Instead, I had to tighten my fingers around my shaft to keep the full condom from slipping off. I sunk back onto the mattress. Boneless, head spinning, heart pounding. If you knew I’d just wasted my load of cum like this, you’d be so mad…you’d throw a fucking tantrum. I laughed. I had to. My little boy pouting and whining because I hadn’t bred him…that was just too fucking cute.
