This is Minami Kojima's final work as an S1 exclusive.
Her first release as an S1 exclusive was on March 19, 2014. For 10 years, she's been creating works with us, and I'm incredibly grateful. Thank you for joining S1 and walking this path with us for a decade.
And now, Minami Kojima enters a new chapter. We'll be watching over her every step of the way.

Being made to cum by my younger sister's boyfriend in a way that's embarrassing for a woman in her late 20s.
No boyfriend, feeling unsatisfied... The emptiness of masturbating while eavesdropping on my sister's couple's sex.
Being caught doing such embarrassing acts, I end up having pity sex with my sister's boyfriend... It's humiliating... Shameful... Embarrassing... But it felt good.
I don't want to betray my sister, but I can't overcome my sexual desires...
Sex with my younger boyfriend was stimulating, but I can't keep doing this forever...
So, on the night my sister was away, I decided to have one last, all-out session with her boyfriend...
