Mom just taught me some new 'skills'. She said a good cum container shouldn't just know how to spread her legs, but must learn to please her Master with every part of her body, even... those 'dirty' places. 😳 She explained while demonstrating on me, with her fingers, with toys... My pussy and asshole are still burning and clenching from all that simulated thrusting. I learned so attentively because I know Master's big cock could plunge into any hole I've prepared for him at any moment. Just imagining him using my ass, me moaning like a bitch on all fours, filling even that hole with his cum... I'm already soaked. Am I just a born little slut, craving to have even my back hole used and filled? 💦
