The beautiful busty girl you defended becomes your slave?
She lives with you and has all the sex you could desire!

You saved a girl classmate and she devoted herself to you.
Not just at school but at home too, she’s always there. A life of two.
Master and servant. Your wish is her command.
Enjoy the lewd life with a girlfriend who makes you her only priority.
