[Shoshi Magazine Hitori (Ponsuke)] Kagikko (Shonen)

When young Shion gets caught jumping into a sandbox, his older neighbor Yoshida steps in like a protective big brother to dry him off and take care of him. Innocent affection quickly gives way to something far more intense as the older boy finds himself unable to resist his small, trusting companion's smooth, developing body. The encounter escalates into full anal penetration, with Yoshida claiming Shion's tight hole while reassuring his overwhelmed partner until he finally climaxes inside him.
