He decides to include Ichigo.

After a moment of thought, and consideration, Kon decided his best option was to employ Ichigo... He got to go to the school after all, and as a Substitute Soul Reaper, Kon imagined that Ichigo would be able to get access to all the sexy Soul Reaper girls...

He pumped his hips into Orihime's mouth as he considered it for a moment, he COULD just use the Note to keep Ichigo's body full time... But he wasn't going to be a dick to the guy. Besides, he knew he would attract way too much attention... And it still wouldn't give him access to the Soul Reaper girls.

He made his choice as Orihime fondled his balls and got more frantic. So he took the Note, and wrote, "Ichigo Kurosaki will become just as perverted as Kon, but retain his demeanor and be good at hiding it. He will partner with Kon, who will share the Sex Note with him. In exchange, Ichigo will use the Note to help him get girls he wouldn't otherwise have access to, and they will share fairly, with maybe a slant in Kon's favor.

"Ichigo will also be unable to see this entry." That last part was just to ensure Ichigo never realized Kon used the Note on him like that, he didn't know if it could be resisted, but he couldn't afford to risk that... Kon then groaned as Orihime brought him off. She moaned as his seed filled her mouth and gulped it down, before she pulled off.
