My girlfriend isn't interested in sex at all. I thought I could stay over at her place this weekend, but... looks like we'll just watch movies or play games... Then there's her sister who just got home, completely opposite of her with huge tits. I can't help but stare at Yuka as she leans forward and uses the fan to blow air inside her blouse. She catches me taking a full-frontal photo of her boobs, and ever since then, I've been fucking around with my sister who betrayed her...
