I'm In Love With My Step-Brother (Markson Fanfic)

Part 7

A few months passed since the move to Mark's house. Mark and I got a lot closer, and we started adjusting well to our new life together with our parents. They were happy, and so were we. Through late night talks and outings, we learned more about each other. We were almost inseparable. Our relationship, not a boyfriend kind of relationship, began entering the experimental stage. We were exploring each other, and developed a more...um...touchy-feely kind of relationship.

--------------------

"Mark! You have 15 minutes to get ready. We gotta meet our parents and their friends at that restaurant soon," I yelled from downstairs. We were the only ones home since our parents were going to the restaurant straight from work.

"Wait! Come upstairs!"

"Why? I'm dressed already!"

"Just come up here, you won't regret it!"

"Ugh, fine."

I made my way up the stairs. This is too much exercise. Who even invented stairs?

"What is it, Ma--" I stopped myself when I saw Mark standing by the doorway holding an oval-shaped device and a dial. It was a glittery pink color, and looked like some toy. "Mark, what the hell is that?!"

"This...this, Jackson, is going to be fun for the both of us. I got this from a friend who runs a sex shop downtown. He gave it to me for free! It's an anal vibrator. You control the intensity of the vibration with this dial. Take off your pants and bend over!"

"WHAT THE FUCK? I'M NOT PUTTING THAT CRAP UP MY ASS! ARE YOU CRAZY?"

"CAN YOU JUST DO IT FOR ME, PLEASE? IT'LL FEEL GOOD, I PROMISE."

"I HAVE NEVER PUT ANYTHING UP MY ASSHOLE, AND I DON'T INTEND TO."

"OKAY, HERE LET'S MAKE A DEAL. If you keep this is in the entire time we're at the restaurant, I'll let you do whatever you want to me tonight. I won't object. AND, I'll do anything you want me to do to you. I think that sounds like a pretty good deal."

"I...that...that doesn't seem so bad, I guess. You're sure I can do anything I want and make you do anything, right?"

"That's right," Mark replied with a smirk, knowing that I was gonna let him put that thing up me.

"Well, shit. Okay. I'll do it..."

"YES! OKAY. DROP YOUR BANDS AND BEND OVER!"

I hesitantly unbuckled my belt. I felt embarrassed pulling down my pants in front of Mark. He was smiling the entire time, it was almost creepy. I dropped my jeans, leaving me standing with my black boxers. It took me a few moments to muster up the courage to pull my underwear down. I turned away from Mark and took them off, revealing my bare white ass.

"God DAMN, JACKSON. You got a nice ass! Can't wait to see what the front side looks like," Mark nearly shouted.

"Could you speak any louder? Might as well inform the whole neighborhood about my butt."

"Actually, I can. HEY, EVERYONE. JACKSON HAS A NI--" I turned around quickly and put a hand over his mouth to shut him up. Unfortunately for me, I forgot I wasn't wearing pants, and my dick brushed past his hands.

"Uh...um...s-sorry...didn't mean to do that," I awkwardly stammered as I turned away once again, avoiding eye contact.

Mark chuckled. "Don't be sorry! You have a nice dick too!"

"Oh my god, don't just say that out loud," I responded while blushing.

"Well, you should be proud of it. Okay, bend over! My friend gave me a tiny package of lube, so I already greased this thing up really well. It shouldn't have a problem going in."
