Eve, The School Slut's Nudist Mom.

Tina Robinson got along with everyone, in more ways than one. Any time, any place, all you had to do was ask, even in the middle of class. Handjobs in math, Blowjobs at lunch, Anal in social studies and Reverse Cowgirl in PE. Didn't matter how many eyes were on her, she did it and loved it and dressed the part as well. Coming to class in micro-bikini tops, miniskirts so short you'd swear they were meant to be worn as belts and not once did she ever wear panties. This girl didn't have an ounce of shame in her body, or so we thought. Tina never shared anything about her home life, never invited anyone over, always changed the subject whenever someone brought up family. The only time anyone's ever seen her embarrassed was when asking her about her mom, to which she'd always reply "Oh god, don't even get me started." Which made us wonder, Does her family know about her lifestyle and understandably disapprove? After finally meeting her mom, It was a surprise to find out that not only was that not the case, Tina was actually the sensible one.

Her Mother, Eve, made her look like a nun.

For once, Tina actually had no problem with me coming over to her house to study for a project we had together. I shared a room with my brother, so studying at my place would be an exercise in annoyance.

"Yeah, I guess that'd be fine. My Mom's supposed to be out all day, so we should have the place to ourselves~"

Naturally I was excited, being alone all day with the sluttiest girl in school. Yeah, we wouldn't be getting any studying done and failing was gonna be so worth it.

So we managed to get through about a third of a page before going at it, my cock was down her throat and my tongue was down her pussy. But then we hear the door creak and for the first time in known history, Tina chokes. Mind you, this a girl who can down a 10 incher like a gulp of water.

"Tinaaaa~ I'm ho- Oh! Don't mind me, keep going~"

"Mom! W-What happened? I thought you'd be out until eleven." Tina said after expertly unsheathing my cock from her face, strings of drool still connecting my lips to her lower lips as her ass ascended from my head while I scrambled to zip up.

"Those prudes caught me and threw me out! Like they've never seen a vagina before." That caught my attention, so i turned and got a look at Tina's Mom.

She was completely naked.

Eve was an absolute fertility goddess. While Tina was very curvy, she was still skinny in an athletic sense. Eve on the other hand was thickness personified, from her enormous slightly-sagging breasts to her matching massive ass, tree trunk thighs and fat mommy belly. However, her youthful face with big blue eyes, plump lips and a waterfall of golden-blonde hair betrayed her mature body, especially her shaved but stubbly pussy that was clearly well used from just how dark and stretched her labia was.

"My my~ Quite the strapping lad you've brought home." Eve licked her lips with lust in her eyes as she sauntered over to me.

"Hands off, Mom! He's Mine!" Tina yanked her mother's hair tight, stopping her in her tracks.

"Oh, You're no fun~" Eve pouted. Defiantly, She spread her legs and pissed on the floor, puddling between my feet.

"MOM!"

"Too Late! I've marked him~ Anytime, Anywhere, Big Boy~" Eve flirted before leaving the room.

"God. You're always like this! AND I'M NOT CLEANING THAT UP! ...Sorry about my mom. You have no idea how many of my boyfriends she's stolen. It's why i'm always so... Fast and loose? When i'm with men... Gotta get with 'em before she does."

"Is that why she stripped down? She knew i was here?"

"Oh, No. She's always naked. Like, she literally doesn't own any clothes, not even shoes or like any jewelry or accessories or anything. You should see her in the winter, walking barefoot in the snow, all red with her nipples super hard. She's totally insane."

"So, she's some kinda nudist?"

"That'd be putting it lightly. I honestly have no idea how she hasn't been arrested already. She hasn't worn a stitch since Dad died. Guess his dick was the only thing that could keep her tamed, and now we're all fucked. God, I've got stories about that woman."

"Do tell."
