After We Did Something Naughty, It Got Messy

Demon girl Ibuki is pregnant before her first period. When natural labor is insufficient, she has intense sex with her teacher to induce contractions, lactates, and goes into labor. In a nap room her cervix dilates to about 8 cm, her water breaks, and the baby's head gets stuck, so the teacher widens the birth canal with his fingers while she pushes through a difficult delivery. Pregnant demon girl Ibuki grips Teacher's hand and pushes through labor. Teacher checks dilation and the crowning head, coaches her pushes, and the baby's head then full body are delivered. Teacher lifts the newborn; Ibuki holds the infant to her breast and says she has become a mother.
