エロいもタイフーン！ ～水も滴るエロエロ妹達と湯けむり温泉ぶらり欲情旅行！～

To put it mildly, it's the best. The landlady is beautiful and has huge breasts. I ended up being persuaded by Sakura to go to a hot spring inn. To be honest, I was really worried about Sakura's high spirits, but I thought I'd be missing out if I didn't enjoy myself since I'd already come. However, while I was excited, looking forward to the delicious food and the busty landlady, what was waiting for me were my sisters, who, as usual, were overly interested in sex. Sumire, who I thought was on my side, has completely matured sexually and is now on Sakura's side. In a different setting than usual, a hot spring, my sisters are using all sorts of sexual methods to throw their sexual thrusts at me. I wonder if I'll ever get a break... right?
