ママの妹の童貞教育 ～ひきこもった僕は外出せずに中出しする～

One day, I became a shut-in.
Thankfully, my parents don't nag me too much.

"Kota-kun, dinner's ready."

That voice wasn't my mother's. It was my mother's younger sister, Mitarai Miki. My parents are currently on an extended trip, so my aunt has come over under the pretext of looking after me. Of course, my aunt wouldn't come willingly. I guess my mother called her. (She's so... pretty... and sexy...)
