"Which would you choose, a girlfriend who's strong when pushed or a sister with huge tits who's weak when pushed?" I started thinking about this not long after I began dating my girlfriend. Although she's someone I'm proud of, she's really guarded when it comes to sex (cry). On the other hand, her younger sister gives off a shy and timid impression. Unable to hold back any longer, I ended up touching her big tits... Hey! She didn't resist strongly (laugh). From then on, I started secretly having intense sex with my super-sensitive sister-in-law, Nami!
