They had always been competitive. It was what had drawn them together. At first it was sports, then simple tasks around the house, and eventually it evolved into silly bets. What would be the next song on the radio? What color would the first truck be that they saw on their way to the store? Who’s dinner plate would the waiter set down on the table first? They settled their score with the loser receiving a friendly punishment or challenge each Saturday.

She had lost almost every bet this week, and on Thursday morning he made her an offer.

“If you can resist waging any more bets with me for the rest of the week, your accumulated punishment will be simply sitting handcuffed to the chair of your choice, naked, for 30 minutes, while I get to touch and tease and play with you as I wish.” He knew this offer would get her imagination running.

She said she wasn’t sure if that was a punishment or a reward, and quickly agreed.

As the day went on, and she thought about it more, she decided to poke the bear. She bet the mail would arrive before noon. She lost. He bumped the punishment up to a full hour. She bet neither of their cell phones would ring between 2pm and 3pm. She lost, and he bumped it up to an hour and a half.

For once she was enjoying being the loser. She kept imagining him touching and teasing her while reclined in the living room chair. She couldn’t wait to be his helpless victim.

She bet him the lead story on the news that night would not be political. She was wrong again. When she reached 3 hours in the chair, he asked. “Are you sure you are up for this?”

She thought for a moment. 3 hours was a long time, but she was not willing to admit that she was in over her head. She said she could handle it.

“I’ll make you another offer.” He told her. “If the thermometer on the back porch stays under 85 degrees tomorrow, I will cancel your punishment. But if it goes higher than 85, then your punishment doubles to 6 hours.

She looked at him with skepticism and checked the weather report on her phone. The forecast was only for 81. She thought for a moment. Three hours was a long time to be tied to a chair. Maybe she should take this opportunity to wipe the slate clean and head into the weekend on equal ground. She agreed to the deal.

Friday afternoon turned out to be hotter than predicted. She lost, again, and started to panic.

Saturday morning he asked her to choose a chair. She had spent a lot of time thinking about the coming six hours. Instead of imagining all the sexy fun that could happen, she was now stressing over accidents she would not be able to avoid. She chose to sit on a patio chair in the backyard. At 10am she stripped down and he tied her to the chair. Her calves were bound to the two front legs, keeping her knees wide apart. Her forearms were bound to the armrests. He smiled at his prisoner, secured by his handy ropework. She pouted at her predicament. Being open and immobilized in the outside air felt very vulnerable and exposed.

He adjusted their sun umbrella to give her shade, played with her nipples for a while, and then went inside. She was left all alone, just her and nature.

Ten minutes later he turned on the backyard stereo with some cheerful background music, and returned to sit next to her. They talked about plans for new landscaping, their upcoming schedule for the week, and what they should make for dinner. Aside from him occasionally reaching over and tweaking her nipples it was a rather average conversation. She relaxed a bit, settling into her place for the day.

He pulled one of her vibrators out of a small bag, turned it on, and placed it on the seat between her thighs. She could feel the faint vibrations through the cushion. She stared down at her buzzing toy, inches from her body. She knew how good it could feel if it were in the right place. She looked at him in affectionate frustration, and then back at the toy. She leaned back and pushed her toes down, tipping the chair back just an inch. The vibrator slowly made its way closer to her body. She rested her toes for a bit and then tipped again. They both watched as the vibrator finally made contact with her skin. It was a bit to one side, against her thigh, but the tip was touching her labia. It was a mild improvement, but still felt so very far from where she really wanted it.

“I’ll be right back.” He said, getting up and returning to the house. She sat there with her vibrator buzzing against her inner thigh. The urge to masterbate was overwhelming, but she simply could not get the toy to touch her needy spot. This was going to be an excruciatingly slow afternoon.

Twenty minutes later he returned with two tall glasses of iced tea.

“You need to stay hydrated.” He said holding out one towards her. “It’s going to be hot out here today.” He smiled an evil little smile. She squinted at him, expressing some fake irritation, and then opened her mouth.

He carefully brought the glass to her lips and tipped it back for her to sip.

The ice tea had lemon and just the right amount of sugar. It was perfect, and felt so refreshing as the cold liquid ran down her throat. The more she sipped the more he tipped the glass. When she had had enough he pulled it away, making sure to dribble a little bit down her chin and onto her chest. The brief chill on her skin made her sit up straight with wide eyes, her mouth still full of tea.

“Sorry about that.” He said, sounding partially apologetic. She glared at him playfully.

Then he leaned in close and whispered in her ear. “As soon as you finish this glass of tea, I’d be happy to hold that vibrator right, where, you, want, it.” There was no one around to hear him, but the quiet closeness to her ear made the offer sound even more naughty.

He lightly flicked her nipple while she thought about it. It had been less than hour and she desperately wanted to cum. She also knew there was no way her bladder was going to hold out for the full six hours. Expecting the inevitable accident was the reason she had chosen to sit in the backyard. The reality of her situation was setting in. She knew she would have to cross that uncomfortable line eventually. Experiencing that embarrassment in front of him was just going to be part of the equation. She looked him deep in the eyes, absolutely loving the control he held over her. She wanted him to make her cum. She made up her mind, gave in with a deep sigh, and opened her mouth for more.
