My name is Cade Michaels. My parents have always been into fitness. They are professional body builders, the kind that do Iron Man/Iron Woman shows for money. They are actually pretty successful, enough to provide for their lives and myself, their son.
My mom, Devon, mostly retired from the circuit to focus on raising me. She did personal training in the meantime. It meant her body was no longer as buff; she didn't have rippling muscles with veins like in her prime. What she did have, was tone. She had more tone than a goddamn London Symphony Orchestra. Her legs, her stomach, her ass, her arms, were all smooth and taut while still being muscular. She was less She-Hulk and more tough looking Biker Babe... and I was into it.
Unlike my parents, I never really got into bodybuilding or exercise. Maybe because I was so surrounded by it, and it made them so busy, I kind of resented it. They still provided high protein meals so I wasn't super overweight or anything.
What I was, was weak.
Probably the biggest reason I wasn't a gym rat was because my mom coddled me and as a result, I could barely lift a dictionary. It was almost scientifically fascinating how little muscle I had. In school I always avoided volunteering to move furniture like desks or cabinets for my teachers because I knew I would just embarrass myself. I could tell my father was disappointed in how I turned out, especially in my senior year of high school being a scrawny weak boy, but my mom was nothing but supportive. She called me a late bloomer.... even though I had just turned 18.
A few weeks ago, I heard my parents going at it. Their door was left open, probably left ajar and swung open itself. I looked in. Dad was on his back while mom was riding him. Dad was ripped as hell, and mom was as beautiful as ever. They looked like Greek statue come to life; like David was fucking Venus. Mom had just the slightest tanlines on her dark tanned skin, and I could see her massive sideboob from my angle. She was riding him for all he was worth, they were more like animals. It was amazing. I went back to my room and found a copy of mom's workout online. I immediately jerked to it and it was the most intense orgasm of my life, at that point.
From then on I was hooked on my mom. My mom made a series of workout tapes. In them she wore form fitting grey sweatpants that hugged her ass, and a tight white crop top. Like all female bodybuilders, she had fake DD tits. She knew what men wanted: tits on a stick. I used those tapes to fuel my new hobby: masturbating. I jerked it while watching her tapes, peeking on her in the shower as well as when she was changing, and I stole her bras and panties to rub on my cock. It was summer break before I would go to college so I had plenty of free time to jerk off to my mother.
One day, mom invited me to the gym with her. Dad was on a tour and she needed a partner. I declined, but she said it was not an option. So, I went with her. After an awkward warm up in which I watched her bend over, a lot, she got on the bench press. She stacked a shitload of weight, it must have been more than I weighed. She asked me to spot her, so I stood over her head. She began pressing the bar. When it was at the lowest, her tits strained against her white sports bra top. When she pushed it back up to finish the rep, her mouth exhaled in what I can only call a blowjob face. She had a usual amount of makeup on; light blue eyeshadow, light pink lipstick, some red color in her cheeks.
I was hard. In my basketball shorts. And my dick was right above her face. I hoped she wouldn't notice. Of course on her last set she looked up to me to make sure I was ready, and my face was eclipsed by my full-on erection. She didn't get mad, instead she smiled, and racked the weight again. She got up and pulled the weights off so it was just the bar.
"Your turn." I protested.
"I'm not even strong enough to lift the bar."
"C'mon, honey. Give it a try." She wiped the bench down with a paper towel after spraying it with disinfectant. Her cleavage was on full display. Her big, perfect, round, bronze boobies...
"It will be... fun." She convinced me. I laid down in the bench and got into position. Mom helped me with my form and got me started. I lifted it successfully, that was the easy part. I brought the bar down until my elbows bent, then the hard part began. Moving this weight at this mechanical disadvantage was practically impossible. If only I could rig up some kind of pulley system or make a robot- oh my god I really was a hopeless nerd loser.
As if reading my thoughts, mom bent over me so her tits were practically in my face.
"You can do it, baby. Do it for mommy." I felt a rush of strength and I completed the rep. Then I did three more. Mom smiled at me. I then got up and wiped the machine down. Mom walked up behind me and hugged me while I was bent over so my head was in her bosom. I felt their suppleness and boobness even through her tight shirt.
"Good job. Mommy is so proud of you." She then swung her leg over the bench and straddled it; as she did, her ass brushed by my semi-erect cock. She sat on the bench and stretched, really accentuating her tig ole bitties. I took a swig of water from my sports bottle with some sports team on it; The Atlanta Turtles or something. Mom stretched one arm high and almost moaned, I looked at her and she said outloud:
"I bet you want to go home and masturbate to mommy's bras, now." I spit out my water. Luckily the gym was not crowded and no one heard her or saw me.
"W....what?"
"Oh please. Mommy knows. You aren't discrete. You know when you jerk off to me in the bathroom mirror, I can see you too, right?"
"I.... don't know what you're talking about."
"I'm not mad, son. I'm actually happy. Happy I found a motivation for you. I'll make a deal with you." She got up and hugged me tightly, then brought her lips to my ear and whispered.
"If you can do every exercise in my routine, tonight, I'll let you masturbate to my naked body." My face went beet red. From both excitement and embarrassment. Mom's smile beamed like a one million watt spotlight.
"Deal."
"Let's get started!" Mom put me through her grueling routine. She reduced weight for me, but many of the exercises were calisthenics, and there was no reducing weight. Burpees, lunges, medicine ball situps, russian twists, jumping jacks (very entertaining to watch her do them), followed by a complete chest and tricep set of 7 machines and 3 free weight exercises. Even with my reduced weights, it was exhausting. But the thought of the reward kept me going.
After the gym we went home and showered; separately, to my disappointment. Mom made a high protein and healthy dinner. Afterwards, I went to my room to do homework. I was starting to think she was bluffing about the arrangement. Then there was a knock at my door. I opened it, mom was standing there leaning in the door frame with her face resting on one of her fists like a model pose.
"Are you ready?" I was hard instantly. I took off my shorts and sat on the bed.
"Honey, you have such a nice cock. Mommy is so proud." She immediately pulled her top off to expose her tits. I started stroking slowly; I wanted this to last. Mom got my intention and started dancing, gyrating her hips and butt as she hooked her thumbs into her waistband. She pulled her sweats off, under them she had white thong style panties with huge ruffles, like what I imagine Victorian era underwear should look like but probably didn't. She continued dancing until she got real close to me, she pulled my head into her stomach and ran her fingers up my neck. She said, breathlessly:
"Take em off." She meant her panties. I reached out and grabbed the sides. This was my first time touching panties on a woman, as opposed to the hamper. I slid them off. Mom had a small soul patch of black hair above her pussy; the pussy I was born from. Her lips I could see in such detail it was about to make me pop. Mom stepped back and ran a finger through her pussy lips, separating them.
"Cum for me, baby. Cum for mommy." Already there, mom. Ropes of cum erupted straight in the air and then landed back on my cock as I furiously stroked it. When my orgasm subsided, I was absolutely drenched in sweat and cum. Mom came close again and kissed me on the mouth; a very un-motherlike kiss.
"Good cardio session, sweetie. Let's go to the gym again tomorrow."
The next day we went to the gym after a high protein lunch. I was still sore from yesterday. As we parked, mom could sense I was hesitant.
"I know you're sore, but you have to go every day, sweetie. It gets easier, but you have to have the discipline to go every day."
"Can't I take it easy once or twice?"
"That's the first step to quitting. Tell you what. If you complete every exercise every day this week, you can have one day off." She trailed a finger lightly on my chest, tracing a lazy figure eight.
"Wow big reward."
"And I'll give you your first blowjob." BOING! My shorts tented immediately.
