It'd been just over a year since Matt and Rebecca moved in together, and coming up on their five year anniversary since they started dating. Their sex life was never particularly dull, or too vanilla even, but Matt recently opened up to her about some of his fetishes and fantasies that he'd held for a long time and would sometimes look up videos and stories of online when she wasn't home.
Becca always tended to be softer and on the more submissive side when things got kinkier, but when they did an online survey together she made liberal use of the 'Yes, if my partner wants to' answer. Matt had exposed a buffet of new kinks for them to talk about. Pegging, Chastity, Humiliation, even fantasies like Forced Fem and Cuckolding.
You don't last five years without communication, and it was quickly cleared up what was fantasy and what was actionable. One Amazon order and two days later and 'Matti' lost his pegging virginity while wearing his partner's underwear. Another few days and his first full day in chastity.
A month had passed and Becca and Matt settled down as the 'new kink smell' started to fade. When he got home from work on friday, Matt was surprised when, unprovoked, his girlfriend asked him to wear his cage. Not just for the evening, but the weekend. He chuckled and couldn't help to oblige, but after his shower. The weekend proceeded to be torturous for him as she hinted at previous sexual encounters from before they met. He, albeit playfully, regretted immediately telling her how this was a fantasy of his as he learned about her several partners. He felt pangs of jealousy both when he found out who got to have the only anal experience with her, and to find out that she's been with more women than he had.
She had recently cut her hair down to a pixie cut before they opened up about their kinks. Before, her long hair would at times conceal her breasts and cleavage, but her C cup breasts were on full display behind her lacy bra and presumably matching panties. He stood about half a foot taller than her with her being 5'4. She decided to steal one of his grey and black flannels to go with her pair of sweatpants.
It was sunday night, when she said she'd unlock him. Matt wasn't sure what to expect but she hinted at how fun it'd be for him to wear some of her more androgynous clothes for this last part. She may even reward him for it. Still, he declined, he wasn't ready to do something like that publicly.
"Okay babe, lets go get gas for my car so I don't have to deal with it tomorrow morning." It was late enough in the night that most commuters had settled in, and this sounded like a BS excuse to get out of the house. Not willing to ignore the call to adventure, Matt grinned and went along. He noticed that Becca went past multiple gas stations like she was looking for a specific one or circumstance. his mind was stuck on the lingerie and all the stories he'd been told all weekend.
Out of the way, at a gas station with significantly poorer lighting and prices that didn't justify the drive, she stopped and parked as the only car at the pumps. She fumbled with her necklace with the key and handed it to him. "Unlock yourself. Get hard, but don't start." She unfolded a $20 bill, "You have until this goes into the gas tank to finish. Otherwise you get to spend the week in that cage." She grinned, not waiting for his astonished look to leave his face before heading inside to pay.
Matt swore as he strained on his cage. This was the hottest thing he could've expected, did she start looking up ideas online? He got himself unlocked and stroked himself a couple times to release the soreness in his modestly sized cock.
He playfully protested when Becca came back, but she shushed him immediately after taking the key back. "If you told me you were into this sooner, when gas was cheaper then maybe you'd have more time." Her cleavage shown through the top buttons of the flannel. "Or maybe if you wore different clothes, I would've put $40 in the tank" she stuck out her tongue before retreating from the window.
The newlyfound domme picked the gas and started to the pump. She leaned back in immediately to offer 'encouragement'. "Better start stroking faster babe, you seemed to like me with other guys try thinking about that." She looked over and saw that the pump was already almost done, but he wasn't. "Or girls. You really liked that." As soon as the pump made the clunk sound of being cut off, and Matt clearly not being finished, he groaned. "Hands on the dash. Now. Stop, stop." She was about to reach in to stop him but he obliged before she had to.
She stopped leaning on the window and got up to finish handling the pump. She stood there for a second, as if trying to figure out how to let Matt win. She spun around after fake pushing buttons on the pump. "Alright babe. Your lucky day, maybe. It didn't print the receipt so I have to go back in. You have until I get back to the car to either put that cage on or finish." She pointed to the disassembled cage on the floorboard. "If you haven't done either, I'm going to take both the car key and your cage key and find the nearest decent looking man or lady to catch a ride home with." She grinned, the threat obviously playing into the fantasy as she walked off into the station once again.
