In this story, "I taught my first girlfriend, who is now my virgin, to have sex with my older sister who lives nearby," the male protagonist has just gotten his first girlfriend. However, being a virgin, he has absolutely no sexual experience and doesn't know how to develop the relationship with his girlfriend in this area. At this time, his childhood friend, an older sister figure, moves back home after many years, and the protagonist talks to her, confiding his troubles!
"You haven't done it yet? So you're a virgin!"
Kana Kusakabe, just like always, treated the male protagonist like a little kid. Hearing that he was a virgin, she couldn't help but pat his head and play with him!
"Don't treat me like a child!" The male protagonist's initial amusement turned to anger. This woman didn't treat him like a man at all. In a moment of impulse, he pounced on her and frantically grabbed her breasts!
"Huh!? Wait... I'm sorry..."
Kana Kusakabe was startled. She tried to calm the male protagonist down but found it was too late; things had already come to this...
"So eager to do it? Then let me help you practice!"
The male protagonist finally lost his virginity, and his first time was with such a great, busty older woman! But virgins have one flaw: they don't know how to control themselves...
"No... not inside..."
Unable to control himself, the male protagonist ejaculated inside her!
"Why did you ejaculate inside?!"
Kana Kusakabe was at a loss with this virgin brother. Naturally, after one time, a virgin would become addicted and want to do it many more times. So, the male protagonist quickly begged Kana Kusakabe to do it with him again!
"More than once, I want to do it with you again..."
Kana Kusakabe, being a sexually active mature woman, decided to give the male protagonist a good lesson!
"Yes, touch slowly... like that, it feels so good there!"
"Amazing!"
Under Kana Kusakabe's constant sexual training, the male protagonist's skills became increasingly refined. One day, as Kana Kusakabe was about to go to his house for a "lesson," she stumbled upon him and his girlfriend in the middle of a passionate encounter, and it turned out his girlfriend was going to move in with him!
"Well, then, there's no need to practice anymore..."
Kana Kusakabe watched the male protagonist successfully reach climax with his girlfriend, feeling a mix of emotions. After all, she had finally managed to cultivate a decent penis? So, in the end, she used a milk cannon to say goodbye to the male protagonist!
However, it's obvious that the male protagonist's girlfriend is several levels below him in terms of appearance and bust size, not to mention her skills and sex appeal. The pleasure they get from sex is completely different. Yes, the male protagonist can't forget the older woman's body and goes back to her for love!
"Isn't it unnecessary to practice anymore?"
"This isn't practice!"
As expected, when it comes to sex, Kusakabe-neechan is the best match. She has big breasts to rub, oral sex, and unprotected ejaculation isn't a problem either. The difference is obvious! Kusakabe Kana also showed a blissful expression!
"You've become a man!"
