[Manpuchi (Nekodel)] Sleepy Sleep Grand Family Planning Scheme [Penguin Piper]

A teacher slips under the covers beside Yuri, his pint-sized demon student, only to find her huge chest already spilling free of her pajamas and her little body running feverishly hot. One push past her impossibly tight entrance and every excuse evaporates—even as he panics that he's just finished inside his own student and scrambles to clean up before she stirs, his hips refuse to stop. Through it all Yuri sleeps soundly, murmuring drowsy jabs about Sensei defiling a bad girl and getting ahead of her classmates, her tail curling lazily as the family planning scheme lives up to its name.
