My stepmom orgasmed on her exercise bike while I was in the room

“Uhhhh what… are you…  talking about?” I stammered out. Suddenly I was extremely nervous and couldn’t help but fidget in place.

“Jack come on, don’t play dumb” Diana responded. “You know what I’m talking about.”

“No really! I don’t! What happened to your bike?” I asked as genuinely as I could. I almost believed it myself as I heard the words come out of my mouth.

Diana narrowed her eyes and stared hard into mine. She took a step closer to me without breaking eye contact.

“You want to play like that? Fine” she said. “You lie just like your father.”

I put my hands up and tried my best to seem dumbfounded.

“Wha.. what? What?” I repeated.

Diana burst out laughing. Not with a laugh like she’d heard a joke, but with a laugh like something inside her had just cracked. She bent forward and held one hand to her stomach while she cackled.

I stood there, uncertain what I was supposed to do.

“Diana what’s going on?” I decided to ask after a bit longer. She perked back up.

“What’s going on? What’s going on Jack is that my bike is not normal.” She said as she tucked her hair back behind her ears. Her smile dropped and she developed a more serious look.

“It…  *wobbles,* Jack” she started. “But I noticed!” She paused. “It only does so while you’re around.” She glanced up at me without moving her head and didn’t say anything else.

Fuck, I didn’t know what to say to that. My mind immediately emptied and my mouth hung open but no words were coming out.

“Mhmmmmmm” she moaned while reading me like a book. “Yeah I do think you know about that” she broke into a huge grin and then went on quickly.

“So I’m going to need you to *fix* it” she commanded with an emphasis on the word fix. “Before I have to ask your Dad to. Okay sweetie?”

“Okay I’ll look at it” I responded without hesitation. “I really don’t know what you mean though I promise” I tried to lie.

Diana gave me an I’m not stupid look.

“Uh huh okay hunny.” Her tone suggested she didn’t believe me for a second.

“It can’t happen anymore Jack. Make sure it’s fixed” she said sternly.

I nodded.

“I’m done with this conversation” Diana let out as she turned and left the entryway. She walked towards the stairs and eventually ascended out of view.

Dread filled me completely. I’d fucked up so hard. God I was so fucked.

After a couple minutes of shock, I finally made my way to my bedroom. I tried to process the situation but my emotions were still high. The uncertainty with not knowing what Diana would do ate away at me the most.

Three days passed before I finally felt my gut start to untie itself. Things had been mostly normal at home. My Dad hadn’t tried to kill me and Diana would still speak to me about various household logistics.

I tried to avoid my parents as much as possible though. That meant staying in my room more, playing less video games and eating dinner out.

One week went by before Diana and I ended up using the entertainment room at the same time again. It was during the afternoon and I was about to finish up playing a game when she came in. Diana made a strong point to say hello to me and I returned her greeting, trying to make it apparent I wasn’t up to any funny business. Part of me felt like I needed to prove a point, so I decided I’d keep playing my game longer.

Diana went through her workout routine and I played my game as usual. She finished up after about 45 minutes then left the room. No vibrations this time. It was normal.

And it was normal for a while after that. For about a month, I played more games and saw Diana more often in the entertainment room. I never activated the vibrator and wasn’t even sure if it was still alive at this point. Then one night, I was up playing late when in the corner of my vision, I noticed the door to the room swing open.

I turned to look. Diana appeared from the dark hallway wearing her purple silken robe. She looked tired and a little messy. Her arms were wrapped tightly around herself and she paced towards me purposefully.

What was this? I thought to myself. I pulled my headphones off my head.

Seeing me do so, Diana whispered “hey” as she continued to close the distance with me.

“Hey what’s up?” I whispered back.

“Um. I was wondering…” she trailed off and looked away. “Did you ever fix my bike?” She finally asked as she stopped next to me. I looked up at her from my chair. Talk about being put in the hot seat.

“Yeahhhh…” I said, unsure of her intentions.

“Oh” she said, seeming disappointed. “So it won’t do… *it…* again?”

I was immediately thrown off and began to stumble over my words.

“Well uh… you.. um..” I started. She cut me off.

“Because I wouldn’t mind if it did it again” Diana stated blankly. “But only if I say Jack, okay?”

I couldn’t believe what I was hearing. I froze and only managed to nod my head yes while I  watched her face for any sign that this could be a dream.

“Thank you sweetie. Now goodnight, don’t stay up too late.” She said as she rubbed my shoulder then turned and made her way out of the room.

The silk robe, being so light and soft, clung to her body, highlighting her figure especially around the hips. I watched the bounce in her ass as she made it to the door. She turned and caught me looking, blushed, then disappeared.

What the fuck had just happened. It was so quick and unexpected. I was seriously convinced I might have dreamt it.

The sound of her voice played over and over in my head. Only if I say Jack. She wouldn’t mind if it did it again? What did she think was going on with the bike? I was thrown off, turned on and extremely confused as to what Diana thought of this whole situation.

But after thinking about it for a long time with my game’s pause screen music jamming through my headphones, the one thing I knew for certain is that I was going to give Diana the best ride of her life.
