"What?! No way... sister-in-law??"
Mei-san, my serious sister-in-law who used to despise me while I lived as a dependent in their house, appeared right before my eyes when I called a delivery health service...
Is this kind of miracle even possible?!
Once I hold her weakness and give orders, her hidden L-cup massive boobs are revealed, and the forbidden service begins.
"Sister-in-law... this feels better than my brother's cock, doesn't it?"
As I ask and pound her hard, she is toyed with by her brother-in-law's huge dick, and Mei-san, who was supposed to hate me, gradually transforms into a female in heat.
From secret groping while the parents are away, to a designated long course at a hotel for immediate fucking!
The sense of immorality becomes the best spice, and I intensely develop her slutty pussy.
The sister-in-law, who at first cursed me as "the lowest," eventually reaches a state of complete surrender, sucking my cock of her own accord.
Sorry, bro!
Your wife's massive boobs are too erotic, and I've pounded her neglected slutty pussy so hard that I've developed her into the perfect female wife lol
