[HMN-298] During my parents' absence, my sister-in-law, who is too knowledgeable about sex, removed the contraceptive condom and used it as a practice table for raw vaginal shot sex. Lara Kudo

"Huh, why are you wearing rubber?" Your brother is my 'servant', so Nama is absolute!" The days of youth when I was treated by my sister-in-law who was too knowledgeable about sex that I looked up on the net! I have knowledge, but the contents are still a brat down! Lara, who is tall and mature, is too cute ... Being used as a practice table for raw vaginal shots, being blamed for freshly learned nipples, being pranked with a large number of toys that were bought ... Little Lara's curiosity never stops!! "I've always been Lara-sama's servant...!"
