Gigi and Merri continued to moan and gasp in sweet pleasure as they let the Mario brothers fuck them in their pussies, with Gigi realizing something as she snapped her fingers.
"Hey Merri, what do you think human jelly tastes like?" Gigi stopped for a moment as she spoke.
Merri also paused for a moment. "You mean, the jelly that comes out of their penises, or vaginas if they're girls?"
Mario raised his eyebrow in confusion, his finger rubbing the side of his head. "Jelly? Humans don't make jelly."
Gigi turned her head towards Mario, taking his penis out of her vagina for a moment. "Yes you do. That white stuff that comes out, it's jelly isn't it?"
"Not exactly." Luigi mentioned.
Merri stood up, doing the same as Gigi as she placed her hands on her hips. "We'll just have to show them by letting them have a taste of our jelly, Gigi."
Gigi literally stretched her flexible jellyfish head in excitement, loving the thought of doing what Merri mentioned. "Oh joy!"
Gigi and Merri turned around, bending down, showing the Mario brothers their bare butt holes as they grabbed their pussies, opening them up as the brothers froze up in pleasure, getting a pair of boners as they rubbed their penises.
"Oh don't do that just yet! We want to go first!" Gigi closed in on Mario's head, sticking her sexy, shiny butt cheeks into Mario's face. "Lick me up, big boy! Lick me up!"
Merri did the same as she giggled with glee. "Taste our sweet pussies and lick them 'till we climax! You'll love it, as will we!"
The Mario brothers, whose cheeks were red with pleasure, decided they had no choice as they grabbed each set of butt cheeks and licked each sister's vagina, causing Gigi and Merri to giggle and moan at the same time.
"Gosh, I sure hope we don't accidently pee." Merri stated.
"Me too. Or worse, fart." Gigi mentioned as the brothers continued licking as they were eating up each sister's pussy, being too busy enjoying the wonderful taste to pay attention to each sister's gross comment.
