A high-tech engineer usually
Have a good income
Most engineers are obese
Sadly unable to attract girls
Gradually lost their confidence
Becoming a slave is their only way
Put on latex and shackles and chastity
Kneeling in front of the Mistress
Worship Mistress's slender and elegant feet
Slapped by Mistress 
Oh yes,you are a real cheap pervert
The Mistress stepped on the pudding with her feet
How despicable you are to eat this trampled food
Yogurt poured on the stockings, poured on the Mistress's huge cock
For you like saw the delicacies food
You are like a hungry beast
But everything about you only can be managed by the Mistress
Eat,kneel,beaten

The Mistress's beauty dick with yogurt is inserted deeply into your mouth
Bursts of nausea
pressed head harder
Tears overflowed from the corners of your eyes
Vibrator and hand job make you seem like come to heaven
But the glans torture after shooting make you fall into hell

You just look forward to this film obediently
