PFES-040 Seven days of sneaking up with your girlfriend's slutty sister.

One day living with a girlfriend, my sister's sister and sister have come to live in our house for seven days, a tall, long, mature sister and a girlfriend as a sister is nothing like... It's the seven days when there's something amazing going on, when there's a body entanglement, and there's a feeling of guilt, and there's a burning of sex that's drying up, and it's not discovered by the girlfriend, but it's slowly continuing to be bold and greedy.
