JUL-511 My return to my hometown is bewildered by sweaty sex with my sister-in-law, resulting in pregnancy through internal ejaculation. Haruki Jun

Koji, who returned home to visit his family, felt a sense of discomfort with the awkwardness between his brother and sister-in-law. Upon hearing their conversation, it seemed they were trying to conceive and having sex every night. Although he tried not to get too involved, he accidentally witnessed the scene... His sister-in-law Jun, noticing him but continuing her lewd display, left Koji transfixed. Desperate for a child, Jun asked Koji for his sperm. Unable to resist her repeated demands, covered in sweat, he ended up releasing a large amount of semen deep inside her.
