During our trip to the hot springs, my girlfriend insisted that she wouldn't sleep with me unless I created a romantic atmosphere. To make her more comfortable, I invited her along with her younger sister, thinking she would help lighten the mood. However, little did I know that the innocent-looking Reika was secretly a pervert who took advantage of the situation by seducing me. Despite feeling guilty about cheating on my girlfriend, I couldn't resist Reika's devilish charm, cute face, whispered dirty talk, and skilled handjob techniques. As a result, I completely fell under her spell during our three-night stay, getting constantly pleasured by her irresistible hands.
