[Ponsuke] Raindrops After the Storm (COMIC Kaien VOL.04) [flash11]

When a sudden rainstorm strands schoolgirl Shizuku and her brother under shelter on the walk home, a forgotten umbrella becomes the excuse for a first-time discovery neither sibling expected. Her curious hands wrap around his stiff dick to make it feel better, and he repays the favor with his tongue buried between her legs before pushing inside her virgin pussy. What starts as innocent concern ends with her legs spread wide, moaning as she feels him moving deep inside and taking his warm load in a blush-heavy sibling first.
