Generational Gap

"Nice ass, Granny~" PS4-tan purred as she patted PS1's fat, plump ass affectionately. "I can't wait to plunder that ass."

"Stop this, girl! I'm your damn grandma! This is wrong!" The mature tan snapped at her grandchild, earning her a hard smack to her rear and making her cry out.

"I don't care," The short-haired woman sneered down at her, stroking her strap-on. "I'm going to make you feel super good, granny. And there's nothing that you can do about it!"

"You're a sicko." Vita snapped, tied to a chair with an annoyed face.

"No one asked you," PS4 snarled back, glaring at her little sister. "Shut your trap and watch." With that, she pried PS1's big buttocks aside and gazed at her holes with lust in her eyes. Her grandma's doughnut-like anus was winking at her. "I think I'll take this hole first~"

PS1 gasped as she felt her older granddaughter spit at her asshole and the tip of her fake cock rub against it. "Sweetie, please, I beg you. Don't do this..."

"Nope." PS4 gripped her grandma's ass and shoved her strap-on deep into her ass, enjoying the howling PS1 made as she burrowed her way inside. "Fits like a glove."

"Pervert!" Vita cried out.

"Says the one watching this," PS4 shot back as she began to fuck the hell out of PS1's ass, her hips slamming against it with each thrust. "God, I love being a part of this family!"

"Four, please, M-My body can't handle this kind of pressure~!" PS1 moaned, gripping the mattress underneath her. PS4 responded by grabbing her large breasts and mauling them. "Ooh~!"

"I'm going to make you cum, and hear you scream!" Her granddaughter growled with unbridled lust as she pushed the button on her strap-on, buzzing inside her poor grandma's ass. "Oh, yeah, I'm getting close~!"

Vita bit her lip, feeling her pussy practically drooling in her shorts. "Fucking incestuous fat-ass bitch..."

PS4 let out a sigh of joy which was covered by PS1 screaming from her orgasm, her juices staining the bed and her milk squirting out from her tits. She let her grandmother flop onto the bed and smiled down at her shuddering form. "You look good like that~"

"Are you happy now?" Vita grunted out, rubbing her legs in anticipation.

"Not until I've fucked our big sister, I'm not. I can't wait to challenge PS3 next." The short-haired tan began to laugh evilly as thunder boomed and lightning flashed outside, despite being a clear day outside.
