satoru handcuffed to the bed and suguru fucking him for hours on end 🥺🥺 he's even crying into the pillows when suguru presses his head down against them, and he's whining so much that suguru loves it more than anything. it just makes him want to hurt satoru even more, whether it be slap his face or spank him until his cheeks are all red and bruised..... bonus points if satoru goes into subspace
