I Was Occupied By A DQN Who Bullied Me And Stayed In My House For A Week And Was Raped! The Big-breasted Sister Who Saved Me Is Skewered And Gangbanged In A 4-way Gangbang As A Substitute, And I Get A Raunchy Boner At The Sight Of Her Falling Into A Heap!

I'm constantly bossed around by the delinquents in my class, and now they've even taken over my home! My sister, who's always protected me since we were kids, tried to kick them out, but that only made them angrier and they ended up raping her. Those bastards covered my proud, big-breasted sister in sperm and mocked her. The nightmare didn't end in just one day. My home became their hangout, and my sister was turned into a submissive meat toilet. At first she resisted and desperately hated it, but then she got high on the pleasure and wore a blissed-out expression! I couldn't suppress my pathetic erection from anger and jealousy...
