VEC-254 Mom's Bosom Buddy Reina Nanjo

Hiroshi was in a bad mood when he heard that a strange woman would take care of him during the trip, even though his parents would leave him alone. Since she is on good terms with her mother, I assumed that she must be a demon hag, but the one who came was a peerless beauty Rei. She wants to deepen her relationship with Reina somehow, but Hiroshi, who is a virgin and doesn't know how to persuade a woman, manages to keep Reina away by telling lies.
