My dad's remarriage partner is a famous beauty on the streets. Plus, she has huge breasts. My dad, busy with work and smoking, isn't exactly on bad terms with Yumi... It's such a waste to have someone so beautiful nearby. I had long since passed my limit of endurance and ended up pushing Yumi down. Since then, whenever my dad is having a smoke, I've been days of internal ejaculation with Yumi...
