[Luxury Lingerie x Dynamite H-Cup Body!] I was invited on a family trip with my girlfriend. While I was resting in the room, her older sister flashed me her cleavage with a devilish smile, saying, "You're always looking at my boobs, aren't you?" I'd always been curious about sexy bodies, and the softness of her breasts pressed against me got me rock hard! "This is crazy! What is this?" she exclaimed, and when she found out, she hid from her younger sister and seduced me with a secret blowjob, until I exploded. Then she called me back to her room, saying, "My younger sister wouldn't do this to me," and when she took off her yukata, she revealed herself in obscene, seductive lingerie! I was instantly turned on, and she gave me a French kiss and a pounding fuck! She then followed up with a continuous cumshot in the shower room, and we drowned in a frenzy of sex until the morning came, seeking excitement!
