One day, out of the blue, my brother's wife showed up at my house! Apparently, she had a fight with him and ran away from home. But anyway, my sister-in-law is really beautiful and has a great figure. I've been secretly admiring her since the first time we met… 'Come on~ Forget about that jerk today and let's drink to our heart's content!' Ugh... I woke up with a killer headache... Hangover... Then my sister-in-law came out of her room, 'Hmm, I drank a lot yesterday. Hey? Hangover? In times like these... Taking a bath is the best! Let's go together!' My sister-in-law still treats me like a kid now that I'm in college! I'm still a virgin and... When she forcibly takes me to the bathroom, my sister-in-law is naked... Her breasts are bigger than I imagined! First-time paizuri! It feels too good! Then, first-time fellatio makes me explode inside her mouth! The next day, to make up, my sister-in-law teaches me sex. My sister-in-law's insides are so warm and tight... First-time sex with raw ejaculation inside!
