[Hoshino Fuuta] Koinu no Shippo to Osatou to {Chin²}

A neighborhood sports day brings an energetic girl and her smaller companion together, but the real event happens after they slip away to a private spot. What starts as her eager, teasing initiative—dropping to her knees and coaxing him with playful confidence—quickly escalates into something neither can resist. She takes the lead with shameless enthusiasm before he flips the dynamic, pressing her down and driving into her with a hunger that leaves them both gasping. Sweet, messy, and full of youthful heat.
