Momoka Ogawa, a teacher of Shimakuri, gave new soap girl Nozomi Mirina a lesson on how to become a top-notch soap girl! They practiced how to please men using each other's G-cup breasts! First, they had a bubble bath in the bath with Momoka's G-cup breasts pressed against Mirina's front and back. After a full-body slippery double lotion massage, Momoka got excited and led them to a threesome in bed. Momoka straddled the customer's rock-hard penis and shook her hips violently, screaming. Mirina inserted the penis, which was covered in Momoka's love juice, and shook her hips just as wildly as Momoka. Mirina became more and more horny under the teacher's influence and finished with an internal ejaculation! Seeing the large amount of thick semen flowing out of her vagina, Momoka was convinced that Mirina would grow into a fine soap girl.
