[Echigoya Takeru] Naisho no Kyouko Sensei (Nyotaika Heaven) [Gentletemptl]

After a hallway collision leaves student Youhei trapped inside the voluptuous body of his teacher Kyouko, he wakes up alone in her apartment, free to explore every heavy curve of her enormous breasts and pantyhose-clad ass firsthand. His private discovery session spirals out of control when classmate Asahi strolls in, teasing the flustered 'sensei' onto his lap for a sweat-soaked, deep pounding she swears is reaching all the way to her womb. Back in his own body the next day, Youhei almost convinces himself it was just a weird dream—until Kyouko's panicked 'you saw nothing!' betrays that their secret is very, very real.
