Kyōko and Konata 69ed each other until they were both ready to start the main event. They did a few minutes of doggy style before going missionary for the rest of their quickie. Konata didn't mind not having an orgasm, because she would feel weak and tired. Instead, Konata let Kyōko ejaculate on her chest. Kyōko thrusted until he was just about to climax, then he took his penis out and moved himself on top of her chest before using his hand to finish the job.
They say that with each twitch, the amount of semen ejaculated gradually decreases until it stops. Kyōko ejaculated onto her chest, around both of her nipples. He then asked Konata, "Would you like me to take a photo of my handiwork?"
Konata replied, "No thanks!"
"Would you like to rub it in?"
Konata did so. She looked at her husband, chuckling. "You're making me all sticky up here and down there!"
Right after that, Konata and Kyōko went to take a bath together. They didn't have sex, but Konata gave Kyōko a soapy handjob, even if he couldn't cum, because it was the sentiment that counted.
As for Yutaka, who knows if she will have a boyfriend who can teach her all about sex? I'll leave that to you to see what happens.
