The guy is lucky with his sister - she is a nipple. She's ready to open her mouth for him to stick it in her. Apparently she serves him regularly, because he no longer feels affection for her, but fucks her like a street whore - rough and bold. However, she seems to like this treatment.
Yes, the Japanese woman herself enjoys that so many males are watching her. Being a bitch in the eyes of men is even cooler than being a geisha. Everyone can come in her mouth, on her face and breasts. She's covered in cum and she's all smiles. Stallions go crazy for chicks like that!
