Three months ago, my dad suddenly got married. I was taken aback by the cohabitation with his remarried partner, Ms. Aoi, who is around my age. At that time, I found out that my old man and Ms. Aoi were having trouble conceiving. If there was any way to change things, I thought I'd like to have sex with Ms. Aoi... And then, Ms. Aoi suddenly came into my room and started jerking me off! It seems that Ms. Aoi, who had been building up sexual frustration, decided to use my dick for her conception efforts instead of my useless old man.
