In the morning, Haruka wakes up, notices the morning wood, and with a tired sigh, gets up to do some exercises. After a while, it subsides. Haruka has grown accustomed to this new aspect of herself but grapples with unfamiliar urges. Heading to the kitchen, she pauses by her sister's room upon hearing some noise. She hears erotic moans coming from the room and curiosity soon gets the better of her and she takes a peak. That's when looking through a small crack from the door she sees Setsuna moving her dick vigorously up and down with a expression of pleasure. Haruka could not believe what she was seeing if front of her, Setsuna was pleasuring herself with her hand. The erotic act was too much for her but could not look away. Soon Haruka's own member was starting to react that's when she stepped away as soon as possible and ran back to her room and exercised again.
Later, Haruka went off to school, but during class, she couldn't get that morning scene out of her head. The fact that Setsuna engages in such acts was surprising, yet it got her thinking. Perhaps it could help her deal with her issue and get through the day, but she doesn't know exactly how to go about it. This is new territory for Haruka, and, not to mention, she never engaged in such activities even before she got the scroll. However, seeing that this could be a potential solution, she figured it's worth a shot.
Soon, school comes to an end, and Haruka heads off to the bookstore to do some research on the subject at hand. Sneaking around without causing suspicion, she walks through the not-too-busy store. Soon, she comes across a biology book on the body and takes a look inside. She studies the male body and finds interesting information but nothing exactly helpful. She continues to look around and comes across another book, more erotic in nature. With a quick hand, she opens it and looks, but it contains way too many R18 scenes for her to handle. As she becomes absorbed, a female clerk comes in from behind and asks if she needs any help. Startled, Haruka says no and runs off, embarrassed by the situation, having learned nothing.
Back, Haruka returned without learning much on the subject and was tired from the whole ordeal. That's when the thought came to mind, and she considered asking Setsuna for help. It would be embarrassing, but considering Setsuna was more accustomed to being a futanari, it seemed like the logical option. Reluctantly, Haruka heads to talk to Setsuna. In the living room, they find her older sister sitting down, playing games on the TV, lounging around as usual. "Hey, Setsuna, playing games, I see," Haruka says to lighten the mood. Setsuna notices and pauses to talk to Haruka, asking what's up. Haruka picks up her courage and tells her that lately, she has had problems dealing with her new appendage and was looking for advice. Setsuna then bluntly says, "Is it the boner?" Haruka turns red after hearing that. Setsuna then chuckles and says it's pretty normal, and she should just ring it out, but Haruka doesn't know how to. Puzzled, Setsuna thinks about it for a bit and decides the best way is just to show. So, Setsuna takes Haruka to the room, and there we see the older sister on the bed with Haruka.
Then Setsuna, without warning, strips Haruka's skirt, revealing her appendage. Completely confused, she asks why Setsuna is doing this. That's when she turns her around and says the best way is a hands-on demonstration, and with an eager look, she gently massages her penis. The sensation was unbelievable, and Haruka could not fathom what Setsuna was thinking but could not do anything about it since it felt unreal. The motions that she was doing to her made her tense up with pleasure. It feels great, doesn't it?" whispered Setsuna into Haruka's ear. She nodded in agreement, and then Setsuna turned it up a notch and increased the rhythm of her hand movements, and Haruka began to feel even better with her penis. Soon, the pressure within her began to close, and Setsuna said it was fine to let it all out. With a sultry voice, Haruka was coming close, as her penis was dripping with sperm. All this time, Haruka could have relieved herself from her erect penis the thoughts in her said. And finally, with a few more strokes, Haruka released her pent-up sperm from her penis, and it all landed on the bed.Haruka, now laying on the bed, panting from this, was in a state of ecstasy from this. "And with that, we are done. I hope that helps," says Setsuna as she walks out of Haruka's room. And so, with this new experience, Haruka has now solved her problem. But new ones have raised.
