My name is Jon, and I have a bit of a dirty secret, I am infatuated with my step-mother. Not in the way you would think though, I don't want to make love to her or anything like that, but I am infatuated with her ass specifically. She is 42, about 5' 10", with short, wavy, brunette hair, and while not the most fit, she has quite a big ass and breasts, she is also a bit snatched. She was always great step-mom to me, but can be tough when she needs to be. Her favorite time of year was summer, because she gets to ride her Harley-style motorcycle, which she told me was the definition of freedom. She always looked good on it, with her ass cheeks hanging over the sides of the seat like saddlebags. I have candid photos of her on her motorcycle from the back and I always jerked it to those photos.
One day, I was jerking it to one of the photos, and I hear a knock at the door, it was her. She came in almost immediately and I had no time to put it away. She looks revolted at the sight
"Gross Jon, what are you doing!?!"
"Nothing!" I say back scared. She startled me and my phone happened to flip over so she could see what I was doing. She caught a glance at it and started walking over to it. I knew there was nothing I could say or do, so I just accepted my fate. She grabbed my phone and get a closer look, then she gave me a disgusted look.
"What is this?" She said with a disappointed and angered inflection, like a dog who had done something wrong.
"Are you jerking off to me riding my bike? Why on Earth would you be hard to this? I am your step-mom." I couldn't think of any reason to defend myself and just looked down at the floor ashamed. I look up and see that she was disappointed in me. Then she gave a smirk and looked down at me.
"Meet me in the garage in 5 minutes, I have an idea for your punishment."
She then walked out swaying her hips, her ass jiggling with every step she took, and closed my door.
I get dressed and head down to the garage. She shows up a minute later in her riding gear. She was wearing leather boots with 2 inch heels and decorative spikes around the ankles. Black leggings that were aggressivly tight on her, like if she bent over wrong, they would burst. They we're pulled up so only a little mid-riff muffin-top was showing. Lastly, a teal crop top that showed off her breasts and a short leather jacket with a black helmet and black fingerless gloves. She struts into the garage swaying those child-bearing hips and shuts the door tightly behind her.
"Now honestly, I don't really blame you for doing what you did to pictures of me. I mean, I have quite a fat ass after all." She then proceeds to smack the side of her ass cheek, the leather of the glove mixed with the leggings made a huge clapping sound.
"But I am still your step-mother, and this does need to stop, so I have a little idea. You are gonna be my bike seat." My face turned bright pink, the idea of being my step-mom's seat excited me but also terrified me.
"Since it seems like you like my ass so much, I'm gonna give you the best view of it. And hopefully this will make you lose this sick fetish you have. First, I want you to worship my seat, so you know what you're in for." I get down on my knees and get my head close to the seat of her black Harley. It was one of the old school Harleys, a pretty small bike designed only for one rider, not like those big crusiers you see. The seat had cracked leather from over the years, and she hadn't changed it in a while. I get my nose close to it and take a whiff, and I instinctively pulled back, it smelt like sweat and ass. She giggled a little.
"Yeah, I ride my bike pretty hard, and have blown a couple of holes in my seat if you catch my drift." I shudder and stick my face back to where I was on the seat. I start sniffing a little, and I looked up at her and she looks at me with a disappointed scowl. She then takes her foot up and pushes the back of my head with her boot and starts smearing my head like getting mud off.
"I want you WORSHIPPING it, I want to hear you inhale my fumes." I start inhaling as loud as I can.
"Good, now lick the seat." I stick out my tongue and start licking her seat top to bottom. I do this for about a minute or so.
"Okay, that's enough bitch." She snaps her fingers, and I stop licking.
"Now, lay down on the bike." I get up and drape my legs over the handlebars and rest my head on the saliva covered bike seat. All I can see now is the ceiling of the garage. She then looks down to me and I see her breasts almost starting to pop-out of that crop-top. She then starts dangling some zip-ties in front of me.
"Just to make sure you can't struggle, I'm gonna take a safety precaution." She then grabs my hands and zip-ties my hand to my ankle. She goes around the other side and does it again. She looks down on me one more time.
"Are you ready for the ride of your life?" She then starts to put her helmet on, and swings her leg over my torso. So, now all I'm seeing is 2 big ass cheeks hovering above my face. I could even see her stretch marks and little imperfections through the leggings. She then hikes up her leggings so her ass leaves nothing to the imagination, I could also tell she is either wearing a thong or going commando. She twerks a little while hiking up the leggings so her ass is consuming it all like a black hole. I can smell a little bit of it already and she isn't the best with hygiene, so I am mentally preparing myself for a thrashing from her ass. I hear her start to countdown with a teasing inflection, dropping her booty closer and closer to my face with every number.
"5... 4... 3..." Before she says 2, she slams her ass down on my face full weight and starts laughing maniacally and grinds her ass on my face. She then lifts her ass up again and takes her concha-style cheeks and spreads them open as wide as she can and slams back down on my face. My head is completely englufed by her ass, all I see is black.
"I hope it smells reaaaaal good down there." She said with a high pitched tone.
"I should also let you know I had some milk and cheese before coming out here. And you know how gaaaaassy that makes me." She wasn't lying, her gas was really bad with dairy products especially. Usually had to wait a few minutes after the bathroom had been used to make sure it was clear. She then goes to unzip my pants and I am at full chub, no way around hiding that. My member springs out of my pants and I hear her gasp a little.
"Wow, you must really like this. Let's see if I can kill your boner." She then leans forward, her anus lines up perfectly with my nostrils. She starts to press her ass and grunts a little, she then blasts a short but canon-like fart up my nostrils. A rotten dairy, sulfuric smell blasts up my nostrils. I start to gag and shake my head trying to get out of the gas chamber. I almost throw her off balance and get a breath of fresh oxygen, but ultimately she regained control.
"Nuh uh uh, now don't be doing that. If you do that again, I'm gonna do something that is worse and you will regret it for sure." She then nuzzles her ass back so that I was engulfed again. The tip of my nose was touching her anus and she kept scratching it against my nose. I heard her giving some soft moans while she did that.
"Mmm, ya know, your face is really comfy. I could get use to this." She then starts shaking her ass on my face, rocking the bike side to side.
"You know what, I'm gonna go for a ride with you. Parade you around the whole neighborhood." I barely hear her say, she had the helmet on and my ears we covered so I could barely hear her. I hear the bike start up, she then leans forward and starts rubbing her tits on my member. She revs the bike a few times and starts dry humping my face with every rev.
"Oh this is gonna be so much fun." I hear the garage door open and then she starts backing up. We suddenly start moving at a pretty decent speed. Now that her feet are on the pegs, I feel her absolute full weight on my face and her asshole keeps going deeper into my nose. Our neighborhood has a few speed bumps,. When we went over one, she threw her ass into the air so it would slam back down onto my face. I was greatful for these moments because I could get a bit of fresh air at least. The vibration of the bike made it feel like she was constantly shaking her booty on my face, and my animalistic instincts started to kick in. She adjusted herself and her ass was aiming straight down at my mouth. I pry open my mouth and drag the back of my tongue across her asshole. She jolts a little from that motion and then leans forward. Then I feel her anus press down in my mouth and proceeds to blast my mouth with a thick, bassy, bubbly, 5 second long fart. She revs the bike while she does this and we go a little faster. She goes over another speed bump, and slams her ass back down, seeming like she wants to brake my nose.
We then pull back into the garage and I hear the garage door close behind me. She stands up from off the bike, and I inhale the biggest inhale of my life. I couldn't be more grateful to breathe in fresh oxygen.
"That was some dumb shit that you did, you almost caused us to wreck." She looked down on my face, beet red, and had a dumb satisfied look on my face.
"But it was pretty hot, so I'm gonna reward you another way." She then gets off of the bike and starts pulling down her leggings, her thighs kinda had a cottage cheese look to them with imperfections, but it looked so hot. I found out she was wearing no underwear as well. She then takes off her helmet and looks down on me once again.
" It seems like you want my unfiltered ass, so I'm gonna give you what you want." She throws her leg over the bike, her legs on both sides of me and her giant bare ass is hovering right above me. She then grips the handlebars and starts throwing it back. Her ass cheeks clap loudly each time they collide back together. And right as they were spread apart, she slams down on my face and starts grinding on my nose. I could feel the sweat from her ass spreading all over my face as she lets out some moans.
"Lick my asshole." She said sensually. I start licking the surface and then start tongue-fucking her asshole. I feel her jolt and moan loudly.
"Oh, you love Mommy's asshole don't you?" I nod with her ass on top of my face.
"Do you want to be Mommy's little ass slave?" I nod again.
"And I know you love Mommy's farts. I'm gonna blow a huge one straight into your mouth, and I want you to swallow every little bit of it. Show Mommy how much you love her." She bends over, grabs the inside of her cheeks and spreads them as far as they go. I stick my tongue out and put my lips around her anus so her asshole can go as deep into my mouth as it possibly can. She unzips my pants, grabs my member with her gloves hand, inhales sharply, and sensually and pushes as hard as she can. She grunts and lets out the biggest, wettest, and bassiest fart I have ever heard from her. She blasts my mouth and feel little pellets of shit hit the inside of my cheeks, this lasts for 15 seconds. I then proceed to shoot thick ropes of cum all over her chest and hand.
"Swallow it, you little pervert." I gulped and it was over. She then rubs her ass over my face to clean herself and gets off of me. She puts her leggings back on and she grabs some scissors and cuts my hands free.
"Man, you are better at this than your dad." She wipes off my face with a rag from the floor.
"Maybe we should do this again. Okay my little ass slave?" I nod in agreement, and then she gives me a playful slap on the cheek and kisses my other one. She then leaves the garage, swaying those seductive hips and closing the door behind her.
