[Kanshouyaku (miska)] A Boy Is Taught More Pleasure Than He Can Fathom [AppleFritter]

Souta-kun is found awake late at night when an older houseguest who claims to have the wrong room uses what he was doing with Souta's mother to corner the flustered boy. Pinned to the floor by his charming, dominant visitor, the slender and exquisitely sensitive youth endures a tight, overwhelming introduction to anal pleasure that leaves him tearful, flushed, and trembling as reluctant pain melts into helpless ecstasy. His soft, yielding body and broken whimpers only encourage his teacher, whose promise of more fun draws a dazed, submissive yes that hints the lessons have only just begun.
