Koibito wa Tomodachi no Haha to Ane: Hito Natsu no Himitsu Taiken

After several years away, a young boy named Toma travels to the countryside to visit his childhood friend's rural home. What begins as a simple summer trip quickly becomes something far more complicated when he finds himself reunited with two women who left lasting impressions on him: his friend's mother, who was once his secret crush, and his friend's older sister, the girl who captured his heart as his first love. Now sharing a roof with them and his oblivious friend, Toma is thrust into an intimate environment where boundaries begin to blur. The atmosphere in the household grows increasingly charged as both women direct their attention toward him. His friend's sister playfully teases him about her generous figure, while his friend's mother takes a far more forward approach, offering to personally guide him through his first romantic experience. Caught between the two, Toma feels a thrilling mix of guilt and excitement at the taboo nature of their advances. As the long summer days unfold under the same roof, he is drawn into a series of sweet, forbidden encounters with both mother and daughter, turning this quiet countryside visit into an unforgettable season of secret indulgence.
