I volunteer at the local YMCA. Not that I’m particularly altruistic, but I’ve installed a series of hidden cameras and microphones in the locker rooms. Every evening I review the day’s footage. I watch both women’s and men’s locker rooms, but especially enjoy the women’s.

There’s one couple — a stepmother and stepdaughter — I particularly love observing. I checked their membership records and saw Lisa is 34 while Amanda’s 21. Both are incredibly hot, and they share no blood relation.

Lisa can be a real bitch. Whenever I work front desk duty, she’s always complaining. Claims we never clean the locker rooms and bathrooms, when they’re scrubbed daily. Heard she’s remarrying soon. Feel sorry for the guy who’ll endure her bullshit. If I didn’t enjoy watching her so much, I’d fast-forward through her segments.

Amanda’s so sweet. Seems genuinely shy and reserved. Has plump tits, a waxed pussy, and magnificent legs. One day she walked in wearing a green tee and shorts. Those legs… I got hard seeing her, thank god for the front desk hiding me.

Last night’s footage showed something extraordinary. The pair were alone in the locker room.

Lisa peeled off her shirt and bra. “Amanda, your tits are really shaping up nicely,” she said.

“Stepmom!” Amanda gasped, crossing arms over her chest.

The stepmother smirked. “Oh come on, take the compliment. Bet boys get real hard for you.”

“Well,” Amanda murmured, “I don’t really like guys that much. I mean, they’re cute, but I prefer girls. Sorry if that disappoints you.”

Lisa raised an eyebrow. “Really now, stepdaughter? Not at all? Ever acted on it?”

“Um… No… But I crave it. Love watching girls in the campus gym locker room, though I try not to stare.”

Stepmom sighed. “God, I envy you — eyeing all those young women with their full breasts and waxed slits. None could be prettier than you though.”

“Stepmom… Do you like girls too?”

“Oh I’ve always liked girls, ever since around your age.”

“But Steve?” Amanda asked. “Your fiancé?”

Lisa chuckled softly. “Oh I’m only marrying him because he’s rich and can fund our lifestyle. Doesn’t mind if I fuck other women — have done it front of him actually. He cums quick watching us, then goes to sleep while I enjoy the girl all night.”

Amanda’s eyes widened. “Wow, you’re so lucky. Hope I can pick up a girl soon.”

“Any particular one in mind?”

“Eh, don’t care much… As long as she’s got nice tits.”

Lisa laughed at her stepdaughter’s rare vulgarity. “Well I find you extremely attractive. And I’ve got tits.”

“But you’re my stepmom! Isn’t that kinda sick?”

“Oh don’t be so puritanical. An older friend taught me everything I know.”

“Really? Well… the thought of being with you excites me. Maybe when we get home?”

“Why not here? Nobody’s around. Besides, getting caught’s always turned me on.”

Amanda dropped her arms and quickly stripped naked.

“Amanda, lie down,” Lisa commanded. “Time for your first pussy licking.”

“Yes mommy, lick my cunt!”

Lisa buried her tongue in the stepdaughter’s slit, causing Amanda’s eyes to flutter instantly with pure lust. The stepmother took her hands and began pinching nipples while eating her out. This continued for five solid minutes.

Then Lisa stood up, pulling off her hoodie and bra. “Amanda, you like these big tits?”

“Oh god yes mommy, they’re fucking gorgeous.”

“Why thank you.” She slid down pants and panties, revealing a smooth-shaven pussy.

Amanda instantly attacked her tits, sucking the left one hard. Slipped her right hand into stepmom’s dripping slit.

“Amanda, bet you can fist me.”

“Sure, I’ll try.”

Inserted one finger, then two, more… Soon had her whole hand inside.

“Oh fuck, pound me!” Lisa screamed.

Amanda started pumping her hand in and out.

“Wanna eat my pussy too?”

“Mmm, I’d love to. Hope I’m as good as you.”

“Don’t worry, I’m an excellent teacher.”

Lisa lay back. Amanda dove in tongue-first.

“Oh Amanda, natural talent! I’m gonna cum.”

“Really? I’m making you cum?”

Lisa started trembling — slowly at first, then violent convulsions. Fluid gushed out, which Amanda eagerly swallowed.

“Thanks, sweetie.”

“Amanda, there’s another thing I enjoy.”

“Anything, mommy.”

“Lie face down.”

Amanda obeyed. Lisa spread her cheeks and tongued her asshole.

“Mmm,” Amanda moaned, “that’s so hot.”

Then started trembling. “Oh mommy, I’m gonna cum!”

Shuddered violently as stepmom kept mouth on ass and hand on pussy.

“Thanks, mommy.” Amanda leaned up and kissed her lips.

“Need to pee.” Stood up heading toward toilets.

“Where you going? Don’t you know I love drinking piss?”

“Oh stepmom… That seems weird.”

“Oh come on, you’ll love it. Lie on your back.”

Lisa placed lips against Amanda’s pussy again. “Go on girl, piss!”

Took a moment, but then Amanda released drops, then full stream. Lisa drank every drop.

“Mommy, love you so much. Maybe someday we can do this front of Steve.”

“Oh he’d probably have a heart attack and drop dead!”

They laughed, then kissed deeply. I bet Amanda tasted her own piss and stepmom’s ass on Lisa’s lips.

“Soon I’ll make moves on one of my friends,” Amanda said. “I’ll let you join.”

Then Amanda froze. “Shit, someone’s coming.”

They scrambled into toilet stalls just as a woman entered.

Fuck, I thought, show’s over. Hope these two keep performing in here. I’ll rewatch this tape again and again and again.
