Oyasumi Sex

When their parents are no longer in the picture, a brother decides that he is going to care for his younger sister. Soon enough his intentions turn sour and lewd thoughts enter his brain…he starts touching her at nighttime while he thinks she is sleeping, little does he know that she is only pretending to be asleep…
My brother’s chapter starts to go to my sister’s room at night because of a small lie.
It was a physical relationship only when my sister was sleeping, but as the number of times increased, the feelings of the two people overlapped, and even when they were awake, they were connected.
Chapter left it to the momentum and repeated vaginal ejaculation, but after seeing Yui becoming an adult body, I came to think that I should not get pregnant.
I went to buy a contraceptive immediately, but I couldn’t because of the embarrassment of being known to the people around me.
Chapters that did not have contraceptives began to avoid Yui’s H, and Yui was having a frustrating day.
And one morning, Yui sneaks into her sleeping brother’s room.
