My stepmother was doing housework when she noticed a blinking anus, which was bad! I couldn't stand my stepmother's big butt because my dad remarried, so I grabbed my own butt and thrust it from behind, then ejaculated into her vagina! It was a strange habit that made me feel like I was pulling my own asshole! Ah, if my body wanted it so much, I had no choice but to ejaculate into her vagina again!
