I'm at my sister's house. I'm changing my clothes and I don't realize that my brother-in-law is spying on me and taking photos of me. I confront him and tell him what the hell is wrong with him. I am your sister-in-law and I will tell my sister about this. He doesn't care and pushes me onto the furniture. He lowers my string and starts spanking me very hard. He does it for a few minutes. After this he kneels me and puts his cock deep in my throat. He does it many times. He pinches my tits, slaps my face and squeezes my nose while he shoves his entire huge cock down my throat. Repeat this for several minutes. He fucks my mouth very hard until all his cum explodes inside my mouth. He asks me to eat it, my own brother-in-law's cum.
