When submissive has been extra naughty I tie her up & Check her boobs slowly turn lovely shade of purple. Nothing makes me happier than hog tying very naughty subby. I like to end my boob torment sessions with pretty orgasm against her will. I will make her get off countless times... over & over & over... while she helplessly has no choice however to let her body obey demands of vibrator long after she thinks she is all 'comed out.' Meanwhile her tits are tie tight & deep purple from restricted veins flow.
