“NO!” Mark yelled, getting the attention of everyone in the office. Becoming self-conscious, he grabbed Lynn by her wrist and dragged her into a closed Office. “No fucking way! Why did you think this was a good idea?” Mark hissed.
Lynn cocked her head to one side. The motion reminded Mark of a dog, tilting its head at you when you tried to speak baby talk to it. Her long black hair cascaded to one side and rested on her shoulder.
“First, because I trust you,” she replied, with a rather endearing smile. Mark had been Lynn’s family friend for many years, and they were more like brothers and sisters. Second, because she has a major crush on you.”
“She’s nineteen, for fuck sake!” Mark growled. “I’m old enough to be her Father, plus I don’t see her in that way!” Mark’s face was beginning to heat up and he could feel the flush come over him.
Lynn shoved him, hard, and he fell back into the executive chair he’d been standing in front of. “And better you than a stranger at a party or one of her classmates in the gymnasium,” Lynn insisted.
Mark’s eyes narrowed as he stared up at Lynn, then he hissed. “And how does Jerry feel about this?” Mark thought he’d just won his case, and sat back crossing his arms imperiously.
“You’re asking that now?” Lynn retorted, her face splitting into a feral grin. “Years ago he asked you to fuck me so he could watch your cock pump in and out of my pussy,” She leaned forward her hands slapping his desk. “How do you think he feels?”
Mark knew Lynn had won. He looked up at her with a defeated frown. “Fine...” he said, after a huge sigh, “But I go only as far as she wants, and I’m not going to try to convince her of anything else.”
Lynn smiled broadly, walked around the desk, and dropped into his lap. Then she kissed Mark deeply but stopped short of a patently lewd face-sucking. It was then that Jerry walked in, a frown on his face.
“Hey!” he yelled in mock indignation. “What the hell are you doing to my wife?”
Lynn spoke first. “He said yes!” she squealed in delight. “He’ll do it.”
“GREAT!” Jerry bellowed. “Should I kiss him too?” Mark held up his arms and crossed them in a twisted crucifix-like motion at that question. Two days later, Mark found himself standing in front of Lynn and Jerry’s house, contemplating the doorbell. Just as he had decided to ring it, the door opened and Mark was face to face with Iris. “‘Sup, Uncle Mark,” Iris chirped. This young woman was an amazement to Mark. From the awkward kid she was, now she was a fully fleshed-out woman. She was perfectly proportioned from head to foot.
Iris was roughly five-foot-six now and had a long mane of coppery-red hair that framed her chiseled face. Her hazel eyes studied Mark with predatory precision and her full, pouty pink lips were curled in a sinister smirk.
She was wearing a white blouse. Or rather one of her Father’s white dress shirts, which was four sizes too big for her. The sleeves were rolled up, nearly to her shoulder and instead of tucking it in, the shirt tails were pulled forward and tied in a knot.
This had the effect of baring her toned, pale midriff, and her skin-tight jeans started just below her hip line and looked like they’d been painted on. A glance down, and Mark saw they were tight enough to give her a camel toe. He looked up quickly.
“Are your parents around?” he asked. “They asked me to come over and take you shopping.”
Iris winked and pulled him inside by his belt. “They left about an hour ago,” she deadpanned as she led him to the kitchen and motioned to a chair at the breakfast nook. She grabbed a note from the refrigerator and set it in front of him.
The now grumpy look on her face told him she had read the note: “Mark. Jerry and I decided to take off a little early. Iris can shop wherever she wants. Use our credit card to pay.” (There was a Master Card taped tot eh not at the bottom.) “She has a One Hundred Dollar Limit, don’t let her go over. Do you remember what we talked about? You two have a good time, and we’ll see you next week. XXOO Lynn.” “PS: I can trust you with my Daughter, Can’t I?”
Mark shook his head and whispered, “Probably not.” That elicited a giggle from Iris, who’d been reading over his shoulder. “Shoo!” Mark hissed and waved a hand randomly up toward Iris.
Iris just giggled and flitted back a few feet. She danced around the opposite side of the table and sat facing Mark. “I know where I wanna shop,” She said with confidence, then reached behind her and slid a piece of paper out of her back pocket.
Mark wondered how that had fit in the pocket, as tight as those jeans were. But he let the thought pass as he unfolded the laminated paper. A silhouette of a naked woman dominated the page, ‘CELEBRATING FIFTY YEARS OF PLEASURE.”
That was the headline. Below that was a listing of items and services. Lingerie, Edibles, Oils, Lotions and Novelties. Then Below that, an address and phone number. A tiny map in the lower corner showed the major cross streets of the shop.
“You want to go to a sex shop?” Mark asked, not a small amount of incredulity dripping from the question. Iris just rested her chin in her hands and batted her eyes at him with a smile. “Fine!” Mark relented. “But we respect your hundred-dollar limit!”
Iris’ smile faded for a moment, then came back. “When can we go?” she chirped excitedly.
“They don’t open for another two hours,” Mark advised. “I’m not sure why I’m here this early, but let’s go get some breakfast, then we can go.”
Iris clapped and ran to her room. She came back a moment later with a small purse slung over her shoulder on a thin leather strap. She opened it and imperiously produced a Drivers License. “Just go it yesterday!” she crowed.
“Yeah? Well, you aren’t driving my car...” Mark grumped. But that didn’t seem to dampen Iris’ mood.
“I know, but they’re gonna ask for my ID right?” Mark’s eyebrow shot up. For a moment he’d forgotten about that. No one carded him anymore. Who’s gonna card a grumpy-looking thirty-five-year-old man?
“Good call,” he praised. “Responsible as well. Okay, let’s get going.”
Mark sat in a booth across from Iris, sipping his coffee while Iris dug into her second helping of Pancakes. He wondered how someone so small could polish off so much food and still have a body like that. Iris looked up and smiled.
She held out a fork with 3 slices of pancake skewered on it. “Want some?” she mumbled through a mouthful. Mark shook his head and sipped his coffee. Iris put down her fork and cupped her small breasts. “Want some?” she teased.
Mark cocked an eyebrow at her and slid the check toward her. “Want some?” Iris frowned a mock frown and finished her food.
“So ... how big is your dick?” She asked suddenly, and Mark nearly spit his coffee out.
“What?!?” He retorted. “Why are you asking me something like that?”
“Well, Dad’s isn’t that big,” She cold see Mark’s questioning glance and said, “I caught him and Mom once, it was about hot dog size.”
“Well, that explains why you’re so short.” Mark joked before taking a sip of cold coffee. That was when he go hit in the face with a sugar packet. He Laughed out loud before raising a hand to attract the waitresses attention.
“Really, are you bigger than him?” Iris asked again, grabbing his coffee cup and downing the last of his cold caffeinated brew. The waitress appeared then and Mark ordered a refill, and Iris asked for a cup as well.
“If you must know,” Mark began. “Yeah, I’m bigger than that.”
Iris’ eyes widened. “Bigger than Johnny the Wad?” she inquired.
Mark wasn’t sure where she’d gotten that name from. ‘Johnny the Wad’ referred to a porn star named John Holmes from back in the eighties.
“No,” he responded, “Not bigger than him,” Iris shrugged. He was sure she didn’t know how big Holmes was. Mark was sure now that Lynn had told her what she’d spoken to him about.
“Look, Iris ... Your Mom made a request of me,” Iris smiled and leaned forward.
“I know, we talked about it,” her voice was low and just a bit heavy with desire.
Mark sighed and sat back as the waitress arrived with two new mugs and a carafe of hot coffee that she set down on the table and removed that old ones. “Thank you,” he said to the waitress who smiled and went about her business.
“Let’s not discuss that out here,” Mark stated more than asked. “We can finish out the shopping and go home and talk about it over dinner tonight,” Iris seemed more than a little put out by that but got over it quickly.
The rest of the conversation centered around porn and Mark wondered if she hadn’t seen any John Homes movies. He nearly choked again when she asked if he’d ever had sex with another guy.
He finally made it to the sex shop. The doorman didn’t ask for her ID but smiled and winked at Mark, giving him a, not too-discreet thumbs up. “Great,” he thought and could tell what the man was thinking. The worst part was, he wasn’t entirely wrong.
Iris had raced about looking at everything, touching what she could and feeling all the dildoes on display. She had tried to get mark to show her how big he was in comparison to the display models, but Mark wouldn’t comply.
Instead, Mark picked up a ball gag and chastity belt and held it out to her with a sly grin. Iris just rolled her eyes and mouthed ‘perv’ as she continued her browsing. She finally came up with what she wanted, and Mark couldn’t be surprised.
“Clone-A-Willy?” Mark asked her aloud. “Really? You have a one-track mind.”
Iris batted her eyes at him. “Maybe I just want a souvenir of our time together,” Mark sighed and shrugged. Iris ran off again and came back with three more items. Two large bottles of something called ‘Dragon Skin’ and a small bottle of ‘Silc-Pig.’
When Mark took a closer look, he found that they were Silicone casting materials and were meant to be used with ‘Clone-A-’Willy’ to make lifelike toys. All in all, the entire thing cost about seventy-five dollars, so they came in under budget.
Mark was beginning to think it was a really bad idea to agree to be Iris first. Not only did he know now that she did have a crush on him, but she wanted to make a dildo of his cock to keep with her. For what, her alone time?
After leaving the store they headed to a more traditional shopping area to just window shop. Mark had been looking to pick up some personal items. Iris on the other hand zeroed in on a novelty shop and one particular item.
“Can I get this?” Iris called out to Mark, who turned to see what she was pointing at. In the window of the shop was a mannequin torso of a woman wearing a camouflage string bikini. The damned thing barely covered the critical areas.
The thing only cost Twelve Dollars, so she would still be on a budget. “Sure...” Mark deadpanned and hustled her into the store. “We’ll get you some Army rank pins and call you Major Pain,”
Iris slapped his arm, hard. “Ow!” Mark shouted. “FINE! Then General Nuisance,” which earned him another punch in the same arm. He bought her the bikini and they left the shop. It would be lunchtime soon.
They drove to the beach at Iris’ request. The got a table at a seaside cafe, it wasn’t anything more than a burger joint with surfing themed decorations, but the food smelled good. While they waited for their food, Iris excused herself and went into the restroom.
When she came out, she was carrying her jeans and had on nothing but her shoes and her Father’s shirt hanging loose, which was roughly the size of a mid-sized dress on her. He realized what she’d done before he could form the question to ask her.
“Planning on taking a swim?” Mark asked. Iris smiled a broad smile at him.
“Maybe...” her tone was playful as she exaggeratedly bit a french fry in half.
After lunch, they did go down to the beach. Mark was positively gobsmacked when Iris took off her shirt to expose her body, clad only in the camouflage bikini. Her skin was pale, and he noticed she did have freckles.
Instead of going into the water, Iris began digging near the shoreline, and began building a sand castle. It took several hours during which time Mark sat in rapt fascination as Iris built level after level of her silica citadel.
People from all around had gathered to watch as well and were taking pictures. Some even set up camp on blankets to watch Iris construct her monstrosity. Mark found himself strangely aroused when she finished as she stood next to it proudly.
Legs apart, fists on hips, hair wet and matted, and a defiant look in her eyes, she stared down at Mark. “Well?” she asked imperiously, “What do you think?”
“Impressive,” Mark stated without hesitation. “And your audience seems to think so as well,” Iris turned, for the first time noticing her on-lookers, she blushed furiously, which just made her pale skin look silkier and shiny against the green bikini and brown sand all over her body.
Cheers erupted from the crowd as Iris gathered up her things and got ready to leave. She greeted and thank many of the people around then we headed up to the public restrooms with showers for her to wash off and get dressed.
Iris fell asleep in the car on the way home. She didn’t even wake up when Mark stopped at the Dragon Wok to pick up some Chinese food for dinner. It was too late to cook and if Iris didn’t wake up for food, it would still be good tomorrow to reheat.
But Iris did wake up when they pulled into the driveway. Sniffed, and sat up. “I’m starving!” she announced, and Mark just chuckled. “So, what now?” Mark asked as they finished dinner. Mark instantly regretted that question as Iris jumped up and came back in a flash with her dildo-making kit. “I don’t think I would be much good right now.” Mark tried. But Iris had other ideas.
“Leave it all to me!” Iris shouted as she began setting out her equipment. Mark picked up each bottle and box and examined them. He wanted to make sure they were all body-safe before Iris went sticking his manhood in any of it.
While he was reading the Dragon skin part A, he heard the water running in the kitchen sink He looked over and Iris was mixing a blueish powder that smelled a lot like toothpaste. “That must be the Alginate,” he thought to himself.
