Q1.
Can siblings bathe together and wash each other's bodies without getting excited?

A1.
Brother (virgin): Getting a boner from sister's tits…w
Sister (big breasts): Since we're family, it doesn't matter if I see my little brother's dick…w

The answer from the close siblings Sara and Osamu.
However, our bodies had developed quite a bit since then.

The sister's breasts grew large, what you'd call huge tits.
The brother's dick was big enough to satisfy any woman, a real monster cock. The charm is so great that it easily crosses the line of 'family' w

The fact that my little brother is a virgin with this dick was discovered.
Moreover, we are in the perfect situation of washing each other's bodies naked.

Here comes Q2. "Isn't your little brother's dick rock hard? And isn't big sister's pussy all wet and ready? How about we have some incestuous first-time sex?"
Who cares about family anymore, let's just start fucking w

A dirty first-time sex till the end. The finale is forbidden internal ejaculation. The pen trial was successful, and the sibling relationship hasn't fallen apart, so let's be glad about that.
