She encounters another woman

The elevator ride down was uneventful, save for Kjersten stretching in the elevator and Lester having the pleasure of watching. Clad in her blue and yellow bikini, she really was a sight to behold: long and toned legs, firm and supple curves, and silky smooth skin. By the time the two had reached the basement-level gym, Kjersten could tell her companion was nervous about something...or was it in anticipation for something? Regardless, she flashed him a smile before adjusting her bikini back into place, softly sighing as she felt the soft fabric rub against her in just the right places.

"Mmm... Haven't worn bikini in long time," she sweetly told Lester, and giggled as she straightened her ponytail. "Very comfy!"

Lester returned Kjersten's smile before reaching into his pockets and realizing something. "Aw hell, forgot my phone! Wanna listen to some tunes when we work out. And maybe take some pics to show off that bikini of yours... Help get you that model gig, you know?" He no-so-subtly shot a look at Kjersten's body. "Be right back, okay? Check out the gym while you wait!"

Kjersten waved to Lester as he went back up, before taking a moment to look around. Many of the machines seemed rather old, and she wasn't up for using the dumbbells and other free weights lying around. She'd rather keep her upper body curvy for her future bikini modeling, and focus on her legs. Then her eyes lit up when she spied what looked like a couple of blue yoga mats laid out in the center of the room. "Perfect! Time for yoga!!"

Kjersten was five minutes into a up dog yoga stretch* (made slightly uncomfortable and arousing when her yellow bikini bottoms began to rub against her clit), when the elevator door opened again.

But instead of Lester, a black woman in workout clothes** stepped out. She had thick, afro-like hair and much more muscle mass in her upper body than the Swedish girl. Her legs were also thick and chiseled, accentuated by her thick ass. She gave Kjersten a dumbfounded look at first, before bursting into laughter. "Oh hell naw! Some skinny white bitch thinks she can take Kalisha's spot? Stretching out in a bikini, really? Can y'all like, move?!"

Kjersten stood up and placed a hand on her hip***, accentuating her own ample posterior (which seemed to irritate Kalisha even more). "Excuse me," the blonde replied with a frown. "That is very rude! And I am not, how you say, a 'bitch'." The flustered girl tried to formulate a proper response in English. "I...stretch here, before you come in. Please, a few minutes more?"

Kalisha only clicked her tongue in distaste. "Tell you what, foreign-accent sounding bitch. Why don't we wrestle for it? Right on those mats you're standing on. If I kick your ass, which I can and will, I get to stretch there. Maybe have a little fun with your fine, knocked-out self when I'm done. Unless you wanna move and let the stronger woman on the mats?"
