あるOLの休日　An office worker's day off (Pixiv Fanbox)

定点イラスト　fixed-point illustration （Lines in the illustration） I've decided to take the day off from work with pay... And then my brother, who was out of college, started jerking me around. It's been a long time since I've had sex in the morning because I've been feeling kind of sexual. Ever since my brother and I got into this relationship, sometimes we have sex without our parents finding out. That... why?　His sex techniques are getting better... Lunch.... I don't cook much, but I made a quick lunch. We had a strenuous workout in the morning and he ate it all up, which he said was delicious. I'm impressed. And then we'll make love to each other until Mom comes home from work. I hadn't realized it had been so long, but he was all grown up. I feel like I'm going to fit in with him.
