˚。⋆୨୧˚ cowgirl tashi is dating your brother
summary: your brother finally starts dating a girl who's tolerable, but what are you supposed to do when you start wanting her for yourself?
ever since he was old enough to date, your brother has had a hard time gaining your approval for his array of girlfriends. the fact that you lived in a small town didn't stop him from hopping to a new girl every month. they were either too prissy, clingy, or vain.
nonetheless, you’d learned to dread the family dinners he’d plan to introduce the new girl he had on his arm.
well, that was until he’d started dating tashi.
your first meeting with her had been… interesting, to say the least. you’d woken up early one morning to find her outside of your brothers room, hopping around on one foot to get her other boot on. you’d frozen when her eyes had caught yours, watching as your brother's new hook-up rushed to get dressed before your parents woke up.
tashi—who you’d come to know her as—just smiled and waved at you before slipping out the back door, the outline of her body showing under the oversized flannel she was wearing.
from that moment on, you were hooked, but you’d die before ever admitting that to anyone. the next few weeks followed just like any others; the family dinner introduction, the movie dates, the late night sleepovers that seeped through your walls and prevented you from getting a moment of peace or sleep. the issue was that your brother actually liked her, and she liked him too.
you’d done just fine pretending to be miserable in her presence for at least three months, until something changed. the more you pushed, the more interested tashi seemed. it started with the awkward third wheel invites to their date nights at the local drive-in, sitting in the front as you pretended to ignore the smacking of their lips or tashi’s wandering eyes as they’d made out in the back of the car.
then, it had turned into small touches after dinner when she’d help you clean up the table, grabbing your hips to move around the small kitchen with a short “‘scuse me…” under her breath.
or the time she’d personally invited you to her family farm, teaching you how to ride one of her horse for practically the whole day until the sun set.
okay, she was growing on you. way faster than you cared to admit. it didn't help that she was the most gorgeous girl you’d ever seen, way prettier than any of your brothers previous flings. she was also nice to you, not because you were her boyfriend's younger sister, but because she enjoyed your company.
it wasn’t until the day of the upcoming summer fair that you’d gained the courage to do something about your feelings. to your luck, your brother hadn't been able to go with you, giving you the perfect motive to beg tashi to take the day off and drive you there to spend the day together.
it didn't take much convincing either. the day had passed quickly, the two of you bouncing around the fairgrounds to visit the animals, carnival rides, and food shops. finally, on the last ferris wheel ride before the fun closed down for the day, you’d kissed her on a whim.
tashi had pulled away from the kiss the second you’d done it, but she didn't say anything, which made your stomach twist and turn with regret. in fact, the entire walk back to her truck was dead silent until you had actually made it there.
without even giving you a second to react, she’d pushed you up against the side of her car in the dark, pressing her palms into your cheeks as she kissed you. all of the thoughts of dread and worry had melted away seamlessly when you returned the gesture, fingers gripping tightly on her belt.
the next moments followed by tashi crowding you into the backseat of her truck, laying you flat on your back as her rough hands snaked down the hem of your dress. your thighs eagerly spread to fit her between the while she busied herself with kissing you, trailing her lips down your neck.
“you like that, sugar?” she whispered hotly into your ear each time you’d whimper, curling her free hand through your hair as it fanned out against the back seat.
the windows in the truck were already fogging up, as if the slight shake didn't make it obvious enough as to what was going on.
her right hand trailed down to the back of your thighs so she could grip your ass, fingers brushing against the panties you had spent ten minutes picking out just for her. “good girl…” tashi buzzed against your skin, reacting to the way your thighs had tightened around her waist when her fingers rubbed against the front of your panties.
“you're being so good for me. already wet, huh?” she smirked cockily, working the fabric to the side before sliding a finger in. your body had arched into hers as her fingers worked on you, sinking in and out while she brought you closer and closer.
“so needy.” tashi continued to encourage you, all the way until you had climaxed, your legs shuttering against her body.
“such a pretty girl.” her finger slipped out of you, right before sliding the rest of them into your mouth to clean up the mess.
