Tôi đụ chị kế của tôi trong phòng khách của bố mẹ tôi và xuất tinh vào âm hộ của cô ấy.

It was Friday afternoon and my parents had to go shopping in the city. My half sister and I stayed to wash the dishes. We couldn't stand it and I fucked her in the living room while they didn't come back. It was very exciting.
