Here are the pros & cons as I see it, I hope this helps. Pros, I couldn't find any, which is saying something! Cons: 1. No true story or plot. 2. Very short. 3. Not even worth the sale price. If you are looking for good AVNs on Steam, I recommend: Acting Lessons, City of Broken Dreamers, Leap of Faith, Monster College, & Sisterly Lust.

Also, it doesn't properly end. It just flouts on a visual on all the women that briefly showed up in the story and you are just supposed to know that there is nothing afterwards.

What happens when a spark ignites where it absolutely shouldn't? My Best Friend's Sister is a sizzling visual novel that pulls you into a whirlwind of temptation, secret desires, and choices that will echo through your life.

It all starts with a typical night out—you, your best friend, and his rowdy crew, drowning in drinks and sharing raunchy stories that would make anyone blush.
