Riley hasn't been giving enough burpjobs and now you're going to take it from her! You play it smart, tying the vibrator to her pussy so as to re-train her to want to give you more of them. She's is cuffed to the foot board, not chance of getting away, You slide your cock in and out of her mouth as she belches for you until you coat her tongue in cum.
