Babysitter's Playtime

Tanya couldn't wait for Alli to show up. Her girl was babysitting today, and the old house already felt alive again. They hugged like no time had passed. Tanya made a quick exit, telling Alli to relax and help herself. She had no idea what that invitation would trigger. Alli wandered upstairs and spotted the bedroom. The clean white sheets looked way too tempting. She stripped fast, lay back, and started rubbing her pussy. To make it hotter she phoned her girlfriend Riley. Riley's voice pushed her over the edge; she moaned loud, legs spread, fingers slick and busy. She never heard the footsteps on the stairs. Tanya walked in, frozen for a second. Alli pulled her hand away, but it was too late. Tanya wanted answers. Alli blushed, explained her real mom Cherri had always said explore, then admitted she and Riley liked calling each other "mom" during phone sex. Tanya's eyes lit up. She asked if Alli would call her "mommy" too. They kissed. Tanya peeled the pillows off Alli's naked body, guided Alli's hands onto her big tits, then dropped her own dress. Alli helped strip the bra, climbed on top, sucked Tanya's nipples and slid two fingers straight into her pussy. Tanya gasped, hips rolling. Alli switched to her favorite move: she swung a leg over, lined up their cunts, and started grinding hard. Tanya had never tribbed before, but she caught the rhythm fast, pushing back until they both came loud and shaking. Alli grinned, already thinking maybe Riley's mom Cherri could join next time for a three-way.
