Based on the anime "Are You Willing to Fall in Love with a Pervert, as Long as She's a Cutie?".

Shining Armor is your average stallion. One day, a mare leaves their panties on his desk with a note that says I love you. While trying to discover the culprit, he discovers his six mare friends all want their way with him, including his sister, and he's left to answer the ultimate question: Are you willing to fall in love with a pervert, as long as she's a cutie?

Warnings fetish and sorta-kinda-incest.
