Follow her into the shower

You activate your invisibility ring and let time resume. The other woman steps into the shower stall while Cynthia puts the phone down with a puzzled look on her face. She peels off her sweaty clothes and tosses them into a gym bag before grabbing a towel and heading to a shower stall two down from the other woman. She hadn't been wearing any panties under the yoga pants, which you had suspected from the prominent camel toe.

Stripping off your clothes and leaving them on a bench, you follow behind her. It's one of those open shower stalls with no doors. Odd for a luxurious country club. Cynthia is already all soaped up and running her hands all over her tight body. She keeps her body in great condition for a woman her age.

You deactivate your invisibility and start stroking your cock while standing about 2 steps behind her. She's completely oblivious to your presence as you stare at her ass and stroke yourself. Then, as Cynthia washes her hair, she turns around for a better angle under the running water and you immediately put one hand on her mouth to prevent her from screaming when she sees you. It takes her a couple of seconds to overcome the initial surprise and recognize you. You put a finger to your lips and slowly let go of her mouth.

"What are you doing here? I didn't know you were a member here," Cynthia whispers.

You nod. "Yeah, just got in," you lie.

She looks down at your cock and grabs it with one hand, stroking it slowly and pulling your body in towards her.

"You know, you left me in a tough spot at the restaurant."

"Ha! Oh yeah, nearly forgot about that. How did you get out?" you chuckle. You recall leaving the mostly bare woman, except for her heels, in the bathroom after fucking her.

"I paid a waitress for her clothes. Now I can't show my face there anymore. And that's one of my favorite restaurants."

By now, Cynthia is standing so close to you that the tip of your cock presses against her belly button as she massages it. Her nipples poke against you and she tip-toes just enough to have her lips inches from yours. You're starting to have second thoughts about gifting her to Robin's husband, but the thought of Robin reminds you of why you are here. That doesn't mean you can't have some fun first.

You part your lips slightly, but wait for her to kiss you. Her lips come close without making contact, continuing to tease you as her other hand is now playing with your balls. Unable to resist her any longer, you cup her small face with both hands and kiss her passionately. Behind you, you hear footsteps walking pass the stall and you wonder if whoever it was had seen you two. Cynthia didn't seem to care as she pushes you off and drops to her knees. The water is falling onto her face so she closes her eyes as she sucks your cock. It was unmistakable what is happening if anyone walked by again.

At first, you thought you are imagining it when you hear moans coming from the direction of the other occupied shower stall. When you hear it again, you know it's the other woman you had seen earlier. Maybe she's masturbating, although that would be a pretty bold thing to do in a gym shower. Your thoughts are interrupted when you realize Cynthia's lips are removed from your cock and she stands. Letting the shower run, she leads you out of the stall to a bench right outside. You can hear the other woman moaning louder now and look at Cynthia to see if she hears it too. She glances in the direction of the moans and smiles at you, before lying down on the length of the bench with her legs spread.

She grabs her own ass cheeks and spreads them apart to let you see how wet her pussy is. You don't need any more prompting and get between her legs and shove your cock into her.

"Yes! Fuck me," Cynthia gasps as you start to pound her pussy. It feels more intimate from the last encounter. Fucking her from behind in a bathroom had been weirdly impersonal. Now, you two are sharing intense eye contact as you fuck her as hard and fast as you can while she urges you on. She's moaning loudly, even more so than the other woman in the shower.

Cynthia's back arches up and she jerks her head back when you feel her pussy tightening around your cock. "Yeah baby!" she screams and it only takes a few more pumps for you to cum as well. When you're done, you lean over her and kiss her, brushing her wet hair out of her face. That's when you realize you can still hear the sound of thighs slapping together even though you're already done fucking.

"Wait, is she?" you ask Cynthia, who smiles back at you. She crawls out from under you and drags you over to the stall. In there, you see the woman leaning against the side wall while some man with a beer gut fucks her from behind. Her breasts are a little saggy, but it's nice to see them bouncing around.

"Hey Cyn," the woman says in between the man's thrusts. "Good session?"

"Oh yeah. Good to see you," Cynthia responds and she heads back to the shower with you right behind. The other man hadn't even looked up from the ass he was plowing.

"What was that?" you ask as you two lather up in soap.

Cynthia looks puzzled. "You didn't know? Didn't they tell you during orientation?"

You shake your head since you're not really a member at the country club.

Cynthia nonchalantly applies soap to your now soft cock. "It's one of the perks of this country club, in addition to the amenities. Members can have sex with each other anywhere and anytime. Though I'd prefer it if some of the men wouldn't grab my boobs while I'm on the treadmill. The locker rooms are unisex and you just walk up to a person if you want to have sex with them. There's a no refusal policy in the agreement you signed, though there are exceptions. For example, you can refuse a man if you don't swing that way. Or a lesbian can say no to a man."

"Interesting..." you say as you massage Cynthia's breasts and play with her nipples. This was an interesting development. You're brought back to reality when her pink diamond ring brushes against your stomach.

"Oh! Right!" you say when you remember why you're here.
