【AXZ】Sugu0 Scramble! Big brother’s sexuality management

This is a story about a SA0 brother and sister having sex at home.
She can’t wait for her brother to get home, so she’s been wearing her jersey, pajamas, and school uniform.

This is the first time I’ve ever seen a girl in the normal position.
