Recently, an immoral game of "barging into a male student's house and raping him" has become popular among gals. A gal who came in last in a karaoke punishment game goes into her target's house and sucks his dick without asking for permission! In the same class as me, an introverted virgin, is Suzuhara, a super busty gal with an amazing body. I thought we lived in different worlds, but one day, that Suzuhara-san suddenly showed up at my house --!? Forced sex with a super busty gal begins now!
