YSN-492 My brother won't let me go, Fuyuai Kotone

Due to his excessive love for his sister, the brother frequently engages in incest. On this day, as soon as their parents left for a trip, he immediately started molesting his sister. He made her perform fellatio in the kitchen, cleaned her genitals with his tongue after she urinated in the toilet, and drank her urine as it sprayed from her crotch in the bathroom. The brother, whose lust was still not satisfied, thrust his rock-hard penis into his sister's tight vagina, making a 'thump thump' sound as he impregnated her, enjoying the act of incestuous intercourse.
