Erik and Xuan had been together as a couple for a few years, and enjoyed each other's company. They lived a rural life in a large white farmhouse, with no immediate neighbors, the nearest being almost half a mile away. It was a peaceful life. They loved to cook together, often making new dishes from their garden out back, read books together and talked about them, sometimes hosting guests, traveling for diversion, or sometimes to visit her daughter.
He had thick brownish-blond hair, was clean-shaven and tan, was of Danish descent, worked out with weights, and his arms and chest were thick and strong. Xuan was Chinese, slight and surprisingly strong and athletic, with alabaster skin and delicate features. Almost half his weight, she made up for it with force of will, and she liked to take charge sometimes, even though fundamentally, she deferred to him as the man of the house.
Xuan's daughter, Ai, was 21, and didn't inherit her mother's porcelain skin, but was a little darker, with slightly rounded features. Slightly chubby, she was an excellent, ambitious student, but shy around boys, and at the nearby university she attended, she focused on her schoolwork. Her friends, Ling and Qian, teased her about her lack of experience with boys, but actually none of them had any experience. Perhaps it was a generational thing, in that social media substituted for life.
Ai and her friends shared an apartment just off campus, but she came home sometimes during summer vacation, and always over Thanksgiving and Christmas break. She always wore baggy clothing, as the kids all did, and she had her own bathroom next to the spare downstairs bedroom. They were always polite and friendly to one another, but the relationship was a little distant. While he wasn't her father, he was her step-dad, and he was helpful with advice. Xuan paid for her daughter's college directly, as she had been a corporate executive for two decades before retiring early.
A couple of nights before all this happened, Xuan and Erik were in bed a little early, and she lay with her head on his shoulder, the sheets and a light blue knit summer bedcover draped over their bodies. Xuan had moved her hand over to his scrotum and cupped it as they talked.
"I'm a little worried about Ai and her friends," she confided.
"Why's that?"
She paused. "They've never even seen a man, they don't date. It's like they're celibate."
"Shouldn't you be happy about that?"
"Maybe so. But they have no experience at all. I mean, not even having seen a man naked, never having had a relationship. All three of them."
"That's how kids are nowadays, I think. Statistically, anyway. They live on social media, at a distance."
She moved her hand under the covers, encircling his penis, which had begun to swell. She had only been with her Chinese husband before Erik, and her husband's penis had been comparatively small, so she relished Erik's endowment. When she first saw it, she worried that he wouldn't be able to enter her at all, and in fact it had been a challenge. They had to use silicone lube, even now. She moved her hand over his swollen magenta glans, and clasped it.
"I wish they could get experience with someone like you."
"Me?"
"You're clean, no risk of STDs, you're bigger than most, you last such a long time, you're experienced. It would be good for them."
"No way. Anything like that would get in the way of our family relationship--I'd never allow that."
She was quiet for a moment.
"How about if you had to help?"
"You mean if somebody forced me at gunpoint? I don't think I could perform."
She laughed. "You tell a different story down here." She moved her hand up and down his shaft. It was about seven inches in length, but wider than her wrist, and she loved the way the width felt inside her, filling her up.
"You're joking," he said.
"Sure," she replied, sliding her head under the covers to put her lips over his penis head. But of course she wasn't kidding--her mind turned to how she might make something happen that would give the girls some real experience. Not just experience, but knowledge, the kind of knowledge that only a guy like hers could give them. But how? It was then that the plan began to slowly take shape.
Their relationship included some room for kinkiness, and to accommodate their shared desire for new experiences, in the last year he had built an enclosed garden in the back, with a six foot high treated wooden privacy fence around it. It was planted with flowers around the edges, including climbing roses, and was seeded with a fine fescue grass in the center. He had installed some silver metal plates with rings on four of the posts, which because they were behind the flowers, were unobtrusive. And she had gotten some thick bungee cords as well as four velcro padded cuffs with rings, for when one of them was bad.
The evening before, she went out while he was tidying up after dinner, carrying the bungee cords and cuffs, attaching and arranging them in the garden enclosure so that they were ready to be attached to wrists and ankles. They had a couple of lounge chairs with long pads, and once in the past, they had used one of those for padding against the ground, over the grass. She took one off a chaise lounge, and put it in the middle of the garden between the four cords.
Then she texted Ai.
"Can you and your friends come over tomorrow morning?"
"Classes are over, and no one's started summer jobs yet, so we could. Why?"
"I have a surprise for you."
Ai sent a face emoji with a raised eyebrow.
"OK. What time?"
"I'll text you when. Maybe be ready in mid-morning."
"K."
The next morning was sunny and calm, a lovely early summer day. They drank coffee together in the kitchen, and made a morning shake for each of them with a mixture of bananas, a mango, oatmilk, and orange juice. After he had showered, dried his hair, and gotten dressed, but before he started his day, Xuan stopped him with a mischievous smile.
"You know you've been bad."
"Bad? How?"
"It's not my job to tell you these things, it's your job to know."
"Really? How am I supposed to know what's in your head? Telepathy?"
"You're supposed to, but you've failed."
"Well I think you've been bad."
"Then we're at an impasse," she said playfully. "Maybe we should flip a coin."
"OK. Heads or tails?"
"Tails, of course."
"Of course."
She took a quarter from the counter and set it on her thumb and clenched fist.
"Ready?"
"I guess."
She flipped the coin, and expertly caught it. Heads.
