Sex ni Zecchou wa Tsukimono!? - Donkan na Osananajimi ni Oshie Konde Mitara...

"You want to know about love, don't you? Tell me what makes you feel good." Yui is reunited with her childhood friend at university. She aspires to be an artist, so she makes a request, "I want to make a good manga, so teach me about love!" It's an unreasonable request, and I'm trying to ignore it, but I end up kissing her with the intention of making her a little surprised. After that, Yui asks me for more than a kiss!? Yui's sensitive body is getting sweaty, and her face is starting to get hot... She's enchanted by her first pleasure, and when I see her, I can't control myself anymore... "Even if she asks me to wait now, I can no longer stop!"
