[SONE-011] I lost my sense of reason due to my girlfriend's younger sister's unconscious glance at her summer clothes... Riri Nanatsumori (Censored)

<p>Her younger sister, Riri, is cuter, more innocent, and super dope than her. However, there is one thing that I have noticed since I met her...that is the summer fashion of modern girls that exposes a lot of skin. Furthermore, while relaxing at home, her pussy muscles are clearly visible through her skirt. Moreover, when she bends over without a bra on, you can&#39;t help but notice her lucky lewd body, where you can see her breasts and even her nipples. Even though she knows it&#39;s no good, she loses her reason due to the defenseless temptation, and before she knows it, she&#39;s massaging her breasts and goes wild. Even though she&#39;s nearby...I&#39;m swallowed up by the immoral pleasure and overheat violently until I get heatstroke. Memories of a summer of people who couldn&#39;t stop their sexual desire and went crazy...</p>
