Lovely newbie slave is given a rough training riding on a dildo and a hard phallus

Bounded slave confesses that she is never good at exercising but this is exactly what master plans to ask her to do. She needs to work her juicy tight pussy around a hard dildo and pecker, riding it up and down till her thighs are burning from her sweet movement. When she does not work it properly, master uses a cattle prod to stimulate this demure darling into submission.
