Coach’s Protein Shake(3)💦

Chapter 6

Alex’s POV

I showed up the next evening like a dumbass who learned nothing. Told myself it was just another training session. My ass still felt sore from last night and every step reminded me of Marcus’s cum leaking out.

I walked in pretending everything was normal. Heart already banging.

Marcus was at the front desk looking tense. He saw me and his face did that guilty twitch. “Alex. You shouldn’t be here.”

“I booked the slot,” I said, trying to sound casual. My voice came out shy and cracked anyway.

He locked the door behind me without another word. We didn’t even pretend to warm up. He grabbed my shirt and pulled me straight to the showers. The tiles were cold. Water turned on hot and loud.

Marcus shoved me against the wall. “This is the last time,” he muttered, but his hands were already yanking my shorts down. “My wife is home with the baby kicking and I’m here again like a fucking idiot.”

He spit on his hand and pushed two fingers in me first. I gasped and laughed nervously. “Coach you said that last night too.”

“Shut up,” he growled, but there was no heat. Just guilt and that hungry look. He lined up his thick cock and slid in raw. The stretch made my knees weak. Water poured over us while he started thrusting deep.

“Fuck you feel good,” he said, voice rough. One hand gripped my hip hard. The other braced on the tile. “Can’t stop thinking about breeding you. Wouldn’t want you walking around tomorrow feeling my load while you hang out with my brother.”

I let out a shaky laugh. “That’s so messed up Coach.”

He fucked me harder after that. The wet slap of skin mixed with the shower noise. Marcus leaned in close, breathing heavy against my neck. “Gonna fill you up good. Pump you full so it leaks out all day.

My little brother’s best friend taking Coach’s seed like a slut.”

I was moaning and trying to stay quiet at the same time. Shy as hell but too turned on to care. Marcus pounded deeper, grunting with every thrust. “This is wrong. So fucking wrong. But I can’t pull out.”

He was close. I could feel him swelling inside me. His strokes got sloppy and desperate.

Then the shower room door banged open.

“Yo Marcus you still here? I brought those protein bars you wanted–”

Jake’s voice. My best friend. Marcus’s little brother.

Time stopped.

Jake stepped in and froze. His eyes went wide.

There I was bent over against the tiles with my shorts around my ankles. Marcus balls-deep inside me, water running down both our bodies, his cock still twitching like it was mid-orgasm.

Jake just stood there holding a plastic bag of protein bars. Mouth open.

Marcus pulled out halfway in shock. A thick string of cum already leaked from my ass and dripped onto the wet floor. “Jake… fuck. It’s not–”

“It is exactly what it looks like,” Jake said slowly.

His face went through shock, then confusion, then something else. Something almost amused. “You’re breeding my best friend in the gym shower? While your pregnant wife is waiting at home?”

I wanted the floor to swallow me. My face burned hotter than the shower water. I tried to cover myself but my hands were shaking too bad. “Jake I can explain–”

Jake cut me off with a laugh. A real one. “Explain? Bro I’ve suspected Marcus was into dudes for years. He’s been weird around guys at the gym forever.” He looked straight at his brother, still half-hard and dripping.

“But my best friend? That’s a new level of fucked up.”

Marcus looked like he was about to have a heart attack. Guilt all over his face. “Jake, listen man. This just happened. I swear. Don’t tell Mom. Don’t tell my wife. I’ll do anything–”

Jake stepped closer, still grinning like this was the funniest shit he’d ever seen. He didn’t look angry. He looked… turned on? “Anything huh?”

The crazy part hit when Jake dropped the protein bars on the bench and started pulling his own shirt off.

“Wait what the fuck,” I blurted out, half laughing from pure nerves.

Jake shrugged, eyes flicking between me and his brother. “If my big brother is gonna secretly breed my best friend behind everyone’s back, the least he can do is let me watch. Or maybe join. Been curious what that dick of his feels like anyway.”

Marcus made this choked sound. Half groan, half panic. His cock twitched again like it had a mind of its own.

Jake looked at me, still shy and dripping with his brother’s cum. “You good with that, Alex? Or you want me to pretend I saw nothing and leave you two to your nasty little secret?”

I stood there soaked, ass pulsing, best friend staring at me naked while his older brother’s load leaked down my thigh.

This was insane.

And the worst part?

I was getting hard again.
