"Hey...you've been staring at my breasts, haven't you?" During a family trip where my girlfriend's sister was having a good time, I was invited to a room in a reverse NTR situation. My lust was running wild because of her lewd teasing of high-end lingerie. (Shirahama Kaho MIKR-075)

[High-end lingerie x bombshell H-cup figure!] I was invited on a family trip with my girlfriend. While resting in the room, my girlfriend's older sister, with a mischievous smile, revealed her cleavage and said, "You've been staring at my breasts, haven't you?" Having always been fascinated by her sexy figure, I got a hard-on from the softness of her breasts pressed against me! "Oh no! What is this?!" After being discovered, I hid behind my sister and secretly gave her oral sex until I ejaculated. Later, I was called to my sister's room, where she took off her bathrobe, revealing a lewd and deadly lingerie underneath! Instantly excited, I was French kissed and fucked! Then, I was chased and repeatedly ejaculated in the shower, continuing my frenzied, thrill-seeking sexual encounters until the morning!
