Since my company's training will be held in Tokyo, I have come from the countryside to stay at my sister's house for about a week. Even though it's been 12 years since we met, I'm so excited because we feel like we're lovers! Even though I haven't seen her for a while, her tits and butt have become so erotic that I can't contain my excitement, even though I don't really want to! When I ran into the bathroom to try to control my lower body, my older sister followed me and found out that I had an erection. "Hey, why are you getting erect? Maybe you got erect when you saw your sister's breasts? I was imagining something naughty lol" With this as an opportunity, we started making out all morning, noon and night. Titty blowjob, brush stroke sex, slimy play etc... Huh? Isn't your technique amazing? Actually, my older sister was a prostitute working at a soap. But that doesn't matter! Because my sister is the best prostitute in this world who is warm and soft and envelops my entire dick!
