Your mistress has a surprise for you, today she's going to train that tight little asshole of yours. She shows you her strap-on and gets you to suck it. Thrusting deep into your throat, she makes you gag on her big dildo, before bending you over and getting you to spread your legs. She starts off slowing, training up your tight little hole before thrusting faster and harder. You're such a good little beta slut for her, aren't you?
