A Christmas Invitation

A Christmas Invitation is one of two episodes to follow With Great Reluctance, the other being The Price of Betrayal.

Plot
The episode starts with Sekai and Taisuke in bed, having just had sex, with the former maintaining an unenthusiastic attitude. When Taisuke asks her what she wants for Christmas, she responds "nothing in particular", prompting him to ask for Makoto's help later.

At school, Makoto and Kotonoha are having lunch when Makoto is completely tuned out. Kotonoha deduces that he's thinking about Sekai and how depressed she's been lately now that Setsuna's transferred away. Kotonoha gives Makoto a blowjob. On their way back to class, they see Sekai run out a room crying, with half her clothes open and sperm dripping from her vagina. Makoto asks Taisuke what happened and the latter replies that it felt too good to pull out, completely oblivious as to what could happen. That evening, Makoto masturbates to seeing Sekai like that.

Alternatively, Makoto can refuse Kotonoha's blowjob, in which case he'll encounter Taisuke sexually assaulting Sekai. Taisuke will then coerce Sekai to give Makoto a blowjob herself, and later that night, Makoto will masturbate at the memory of having Sekai's mouth and tongue on him. Taisuke then calls Makoto to talk about their Christmas plans and asks Makoto (along with Kotonoha) to come with him and Sekai to figure out what Sekai wants for Christmas.

That Saturday, the four meet up at Sakakino-cho Station. Taisuke arrives late and as punishment, lunch is on him. At Jo-Q Hands, Taisuke goes off with Kotonoha to give Makoto a chance to figure out what Sekai wants. Sekai buys a photo stand because Makoto liked it and before he can stop her. Later, Makoto tries to find out what she wants, but she doesn't want anything else from the store. Meanwhile, Kotonoha has gone shopping, using Taisuke as a pack mule. They later decide to call it a day and go home when Makoto subtly asks Kotonoha to go on her own so that he can find out what Sekai wants. Sekai and Makoto take the train and Makoto asks her if there's anything she wants. Sekai answers she can't have what she wants. Makoto wonders if it's something expensive but Sekai says it's not something you can put a price on. After some prying, Sekai reveals that she wants Makoto. Makoto then watches as she leaves on the train.

That evening, Makoto and Taisuke talk on the phone and Makoto tells him that Sekai wanted an antique-looking photo stand, but she bought it right there already. Kotonoha then calls him to ask about the present. Makoto tells her that he failed and then mentions maybe Sekai wants something that can't be bought with money. Kotonoha then says she will ask her herself.

At lunchtime the next school day, Kotonoha meets Sekai on the rooftop. She asks Sekai if she wants anything at the moment. Sekai doesn't understand fully and answers what she wants for lunch. Kotonoha asks if she wants anything important and Sekai replies she wants a dad, but also mentions that her mother described her father as a hopeless good-for-nothing. Kotonoha then asks Sekai's advice. She tells her that she's been having sex with Makoto because he wanted it but now she's the one who wants to do it and Makoto's not interested. She then reveals that she plans to get a hotel room in Sakakino Hills through her father's connections and become one with Makoto. She reveals it would cost 400,000 yen and asks if Makoto would refuse. Sekai says she doesn't think he would refuse. Kotonoha is relieved and asks Sekai to lend her her support.
