Review Detail of Sad_ in Nee-chan is a Soap Girl!? (18+)

The MC is pathetic but at least it's realistic, he's a virgin so he sucks at s*x and thankfully he's told that and they don't have s*x for like 10 hours in a row like you see sometimes, so I have to give it a high rating. It is quite a sweet story in the end with a tsun-tsun big sister.
