It Adds Up to X=TASY

Donnie had never bucked against anything in his life, though he had wanted to; he had never stepped out of his marriage; a retired science teacher he did things by the numbers, calculated the risk reward and while he was tall, still had his hair and worked out with regularity, never saw Amber coming.

Let's see what happens when two geeks with opposite formulaic attitudes about sex cross paths, with diatomically opposite moral formulas, after running intersect with one another's desires.

**************************************************

Donnie Franklin, 61, ran into "Farrells", the local grocery, for last minute items for supper. A retired teacher he had just been subbing at the local high school, when his wife (Mel, 54, seven years younger) texted a list of the necessary items.

It was early September 2026.

He was frustrated with her because it was the third time this week that she'd changed menus on him causing him to food shop after subbing AND she had been denying any advances he'd made sexually.

"Hi Mr. F!" a young, perky voice said.

Turning to see the blonde courtesy worker manning the self-checkout, he was relieved to see the name tag matched the name in his head, a causality of being 61 was his memory some days.

"Hi Shelby!" He said eagerly, her mousey good looks highlighted by stringy wavy hair she did up nicely every day when she was a student in his science class.

They caught up on where she was, a sophomore at the local community college, 20, still undecided but leaning towards becoming a Vet Technician, she was impressed he remembered. Donnie had just lost his dog, a 15-year-old Lab named Goldy, and she talked about how it would be a tough part of the vet tech world for her to put animals down (a profession she had considered but was still undecided after two years of community college).

Shelby gave him a half-hug, and when he turned back, he saw her looking at him, down below at his backside, then blushed and turned away while he went on with his shopping.

'I'd nail her so bad'. he thought, though his "nail" wasn't as strong as it used to be, it still operated and he could feel himself harden a little while walking the aisles.

Donnie sized up every interaction with a young, doable woman. He did his usual dismissal because of the high risk in all categories, wife is at home, Shelby was working until 9 p.m., she knew him and she was flaky enough to spread rumors.

He stopped his list of hurdles right there - no need to calculate the risk number, not to mention he couldn't imagine her being very imaginative in bed, so the reward didn't matter.

In reality, imagination was all Donnie had in his life. He had built a nice collection of sci-fi/fantasy erotica on a website. He loved to write, even had a stint as a freelance writer for the local paper while teaching. His erotica centred around a character much like himself, just pumped up physically and endowment wise. In real life his six-inch cock was only getting to five inches these days, and his once muscular physique was past the Dad bod range, though he'd dropped 10 lbs. recently.

He and Mel would have sex a couple times a month, mixing it up a little but mainly missionary and goodnight. They had been very good about changing positions and doing things in public or at parks, but nothing involving others and anal was definitely off limits. He also rated themselves at a 5 (out of ten) for freak level, and looking at Shelby, she'd be just a two or three.

What his calculations and formulas didn't know was Shelby was banging her manager, a 54-year-old married man, almost daily and was in her "out there" stage of sexual exploration. She'd connected randomly with several other older men, preferring them attached so she could still live her life, and had held a liking for "Mr. F" since her school days.

At the end of the day Donnie's numbers had him bypass another opportunity and went about the task of finding his wife's dinner items. Shelby's flirtation pushed him towards really pushing for some version of intercourse that night from Mel, his wife.

Outside of Farrell's, Amber Wattleywas working hard for the ASPCA animal rescue organization, a paid (if you could call it that) position that had her traversing the Midwest at locations that had a soft spot for stray animals. It's a national brand; the ones that pull at your heart strings late at night with sad and abused animals, asking to sponsor them with a year-long commitment to donate monthly.

It was her second job, but one that paired with her real job easily since it had her out all over the Midwest in big and smaller cities.

But more about that later.

"I swear if I can get one more, our entire facility will be funded for the year, well at least for my favourites," she said to Russell, her colleague, a smart looking black man. Both were 28, had done the college thing and both had parents who were supportive while pursuing various "Save the World" endeavors.

They had driven out from Colorado, with stops in Lincoln, Omaha, Des Moines and now Cedar Rapids on consecutive days. They were actually going to spring for a room tonight, rather than sleep in the cargo van the organization provided.

When bored, Amber fucked. For her other job, Amber fucked.

She and Russell had hooked up a lot last year and were tired of each other physically, having met in college and only connected when really drunk or high now, often masturbating in the van beside each other instead.

She was wearing a light floral-patterned sundress, which opened up her cleavage nicely, Russell teased that it's why she was leading him in commitments.

"You can see right down your shirt, Amber..."

"Into my soul you mean..." she said; attraction was the connection point to each other's spirits.

She had already been hitting off her THC vape; it was Friday and with the room she was motivated to find someone to "experience" and "evaluate." She'd not told Russell of her other job and how it necessitated her "surveying" men across the Midwest about their sexual activity.

She saw Donnie and smiled; an evil grin came across her lips.

"Hi, Sir can I take just a moment of your time, I can see you're really busy."

Donnie looked into her fresh face, delicate false eyelashes, porcelain doll lips, creamy white skin that flowed into her open dress, breasts not propped up but perky and open to see.

"Of course," he said with delight, the scenery so lovely; meeting Shelby had gotten his juices flowing.

Her delivery was very scripted; her eye contact was deep and attentive. He had said goodbye to Shelby inside talking about his dog that just passed and felt in a mood to give to a reputable national organization that sponsored pets especially if this young, attractive woman was pitching the cause.

She continued and he committed, after she said it would only take 90 seconds to complete the form, he knew that was incorrect and wanted to test her data. Donnie got out his credit card and signed up for the $20 a month program, which was verified by the national organization.

While he was entering his card information, Amber opened the door to him at least running his calculation.

"We're from Colorado, Donald (not what he told her, but it certainly was sexy that she heel-turned on his name), staying here tonight. Where's a great place that we can have a group night out for dinner?"

"Umm, "Cropdusters" is straight down this road to the left."

He wrapped up the entry and handed it to her as she filled out a 'thank you' card.

He'd not even evaluated his chances of hooking up with her, since they had such official looking badges and things knowing they were from out of town before she told him.

"If you don't have plans for dinner tonight swing by, what is it?"

"Cropdusters" Donnie said. "You'd better write it down."

"Yeah," she giggled, doing just that. "We're checked in already and are wrapping up here in about an hour."

Amber looked at him, her hand tucking her dyed pink hair behind her ear, her smile wide and inviting.

For one moment he thought about it, how could he get out of dinner and "run into" them alone. His mind was quick with the 'initial run' of numbers. A 10 for stranger; A 10 for looks; a 7 for probably since she invited him; a 10 for location since she said they had a room; a 1 for able to get away from Mel.

"Impossible." He said out loud looking back. Letting the numbers again run his life.

Who are you kidding...the negative, raised feelings in him; he'd run the numbers a few times when Mel was at a conference for work the past year after running into potential hook-ups.You'd never go through with it OR find someone who would.

Amber was on the phone in tears giving her friends the good news about meeting their quota with an hour left.

Donnie turned, she waved whilst talking.

She ended the call and went and hugged Russell.

"You did it," Russell said, also giving her a quick kiss, knowing she'd be in a good mood and unless someone turned up, he would enjoy a high and drunken romp with her in a hotel tonight.

"I'm going to find someone, no offense," Amber said. "I've got a feeling we'll see that one later."

"The old Dude??" Russell said in a high-pitched voice. "Since when are geeky, grey haired men your thing?"

"Since today and forever! And you don't know everything about me." she said with excitement. "My luck he'll not show."

"I know your body my sweets and it will be my luck he doesn't show," Russell said, she frowned and he changed his tune. "Or you can pick up someone else."

"Doubtful, plus I bet you are the hit of the place and won't have time for me anyways."

"Yeah, true dat!" he said and they both laughed.

Truth was Amber had parlayed her college experience into surveying people sexually across the Midwest and was doing a paper about being openly sexual with both men and women. She needed older partners and had been reinforced time and time again that the older they were the kinkier, and more affectionate they were at the same time.

Personally, she calculated how she thought a man might be in bed, giving a point and trait for athleticism, earning power, straight advice and personality. The process took 15 minutes and, in that time, "Donald" earned points for giving her money advice, talking his favorite muscle groups for working out and that he had planned well for retirement.

His story of his dog also drew her in and was the reason she opened the door by inviting him to dinner with her glances and giving him her number.

At Donnie and Mel's house

"Change of plans," Mel said, a bag over her shoulder and headed out the door as he came in through the mud room.

"Cheryl can't stay with Mom tonight, her daughter surprised her and is landing at the Cedar Rapids airport in 30 minutes," Mel said rushing past. "You can find you own dinner and I'll see you for lunch tomorrow."

Her mother's procedure required 24-hour supervision afterwards and help cleaning and getting her able to move around her condo. Cheryl was going to do that, since we'd harped on at her mother to find others who would help her at her age.

"Okay..." Donnie said seeing her rush into her car and drive out, closing the garage door.

He set the items he didn't need for supper on the large expansive island, the donation information and personal note from Amber in his hand.

Donnie contemplated going to "Cropdusters", maybe running into Amber but thought he was reading too much into the interaction.

"Right, a 20-something wants you old man, sure."

He opened the pamphlet and found she had written a personal thank you.

'Sorry to hear about your dog's passing. You'll save three animals with your donation, so be proud and it was a joy to meet you. Stop down to "Cropdusters" if you can - (drawn heart) Amber.  349-232-0974.'

"Fuck"...he thought. "She gave me her number."

He ran the scenario through the initial evaluation, it was perfect.

Out of the house till noon tomorrow (wife out of the way); gave me permission to go get dinner somewhere, and "Cropdusters" was their favorite (phone would locate him in a place he'd go); I could have my phone set to answer and for her to track (no deception needed); He could go somewhere fast with her or better yet, bring her home! (Location of the act)

He texted her, "Hey this is Donald and I'm going to stop down if you're going to "Cropdusters"."

She 'hearted' his message and returned with - 'We're heading there now...with a clapping emoji.'

It had been about an hour, Donnie felt himself getting hard just thinking about going there, seeing Amber again. He was sure as fuck going to give this a try, his formula was as perfect as it could be, even for the overnight and the potential for bringing her to the house.

"I could call Mel several times if I wish," he said, almost giddy as the alibis were countless.

The nerves didn't kick in until he pulled into the parking lot and got out of the car. He did have one red number in his formula, if they ran into someone they knew (accidental detection), but he was ready with the story that she would be one of his former students. So it ranked a two of 10)

"Near perfect..." he said about his formula exiting the car.

He walked in; Russell and Amber were chatting with three girls about Amber's age there for happy hour after work on a Friday. Amber had been watching the door, looked over, saw Donnie and bounded over to him.

"You MADE IT!"

He hadn't hugged another woman like that in over 30 years of marriage, her body melted into his arms, he wrapped and squeezed and her leg moved between his and there was a bit of a grind, breasts nicely pressed beneath his chest.

"Donald, I'm soooo happy!" she cooed into his ear. "Your donation...oh, I can't say how much that means to me."

Her leg lingered, pushing in, sliding up as she flexed her feet, and down letting it release.

"Can I buy you guys a drink?"

She smiled, took my hand and pulled me towards the group.

"I'd love that," She let go and bounded back to them, getting the bartenders attention, we all ordered and soon everyone had another set of two for one happy hour drinks and we were toasting Amber's hospital.

The three young ladies were really into Russell, the slender, long deadlocked black man's charisma getting their attention.

"No wifey tonight?" Amber threw it out there, her finger touching his wedding ring. I downed a beer quick, looked at her.

The drink on an empty stomach combined with the strong IPA, kicked a buzz.

"Let me..." he said holding up one finger, the universal "one moment" signal getting out my cellphone, hitting his wife's picture on the contacts, getting a raised eyebrow from Amber.

"How's your mother?" he asked Mel, right in front of Amber who's eyes were now wide.

"Yeah, "Cropduster's" is crazy, so I'm having a drink at the bar.  I ran into an old student of mine from the Norwalk days, Amber."

She slapped her thighs, dropping her head down between her legs, flying back up her hair whipping over her face then to the side it went with her hand.

Donnie held the phone out to her and nodded at her to speak.

"Hi!" Amber said with a devilish smile, then covering her mouth.

He listened for a moment for a quick update on her Mom, no issues just resting.

"Still planning on coming back, around Noon tomorrow?" He asked, Amber's eyes getting intense, looking me up and down, her hand now resting on my knee. "Yeah, I'll be doing yard work most likely after a workout."

Mel said she was concerned about her Mother's behaviour so it could be a little longer.

"Or she'll just want breakfast mid-morning...who knows?"

"Let me know...love you, Bye."

"Donald, you're naughty..." Amber slid her hand up his thigh, running over his hard cock. "I like naughty...a lot."

He leaned in close, his lips just inches from hers, went to her neck and whispered in her ear.

"I want my cock to be buried deep in your pussy, pushing deep when I call to say goodnight to her."

Amber looked up into his eyes, they were speaking the same language.

"That can be arranged," she said.

(Donnie's POV)

Amber went to Russell, leaning in and looking at me talking. She handed him the keys to their van and we were out the door.

"Let's go..." she said heading to the door, not even looking back at Russell and the group. "Fuck, I'm so wet right now,"

We climbed into my car, her breasts opening to me from the dress, a glimpse of nipple.

"I can smell you..." Smiling my eyes glued to her breasts, then her face which gave off pride in her ability to draw me in immediately.

We pulled away, she leaned the seat back and opened her legs, hiking up her dress, sliding her hand under the panties and jamming fingers inside.

My mouth dropped while we wheeled to a stop sign and through it, her hand pumping herself, the other hand on her chest, pulling down her bra and dress.

"Taste..."

She moved her fingers swiftly from her cunt to my mouth, leaning forward, her full breast out.

"Mmmmm....good thing I don't live that far away."

"We can still have a little fun." She said and slowly leant forward, pulled at my shorts, unbuttoning and unzipping while I was stopped at the stop light. "I wanna little taste of you as an appetizer."

"We got all night..."

"We do indeed," and with that she covered my swelling cock with her mouth.

"Ohh...Amber...fuck..."

Quickly she was bobbing on my cock, licking and slurping, holding her hair back, my hand resting on her shoulder.

She looked up; that devilish smile so infectious, licking her lips and going back to work on my flesh.

I was happy she was down there, driving with a hot young woman into my neighborhood might be problematic, though I had several statements already formulated if asked. We weren't there yet and we swung out into the countryside.

Her mouth was wet and warm; she pushed down and undid the seatbelt. We had been driving a few minutes and had cleared the double lane possibilities where someone could pull up beside me.

"Mmmm..." she said licking her lips and looking up. "We're going to have soooo much fun tonight."

She laid back, taking her mouth off of my cock, her panties still exposed, her hand on my cock stroking it slowly, just looking out of the window, fiddling with her nipple.

"What made you decide to join us?" she asked looking at the farm fields.

"Ohh....Amber...you're getting me close..." I looked over.

"No worries, I'll just clean it up, I didn't have dinner yet!" Again the devilish smile. "I soooo love the taste of cum and I have a scale to rate it in taste, consistency and amount."

"Mmmm. I like a 'numbers' girl." I said, answering her question.

"Do you? Wow, you're into them?"

"We have a 97% chance to pull off a night of unforgettable fun....Jesus...I'll just tell you to cover it if I begin...Ohhh..."

I quickly explained to her my infidelity ratio, and how perfect this situation was for meeting her at dinner.

"We're approaching my block, could you..."

She was moving before I opened my mouth, read my mind, going back to my cock, ducking her head, lips just on the tip sucking slowly, eyes looking up, almost smiling.

"Jesus, shit..."

I pulled in the garage, I hit the button to close and she hopped up and pushed her face down on my cock.

"AMBER! OH! FUCK!"

I shot a stream of cum, one spurt after another, into her mouth, she expertly sucked and swallowed, pushed deeper, her hand at the base milking more out of me, squeezing my balls as they tightened. Her back arched, she strained and pushed, willing as much cum out, finally pulling up off my cock and kissing me.

"Mmgftt!" our mouth joined for the first time, the smell and flavor of my own cum a treat, her hands on my face, leg crossed over and she was in my lap.
