Sora was in a real hard spot here. He really didn't want to expose himself to Selphie. That would give her yet another thing to hold against him...
"I'm waiting!" Selphie said, scrunching her toes over Sora's erection, "Or would you rather me just go talk to Kairi?"
Sora surely didn't want that What would she think of him after he went to Selphie and things got this far instead of going to her? One thing was certain, it wouldn't be a very positive reaction.

Reluctantly, Sora pulled his pants and underwear down to his knees, revealing his erect cock to Selphie.
"Good, now just relax while I show you why I'm better than Kairi to go to for this.
With that said, Selphie placed her soft feet on Sora's hard member, making him flinch and gasp in surprise.
"Ah... S-selphie... don't!"
"Just relax, Sora." Selphie repeated. Then, she started rubbing her luscious feet up and down Sora's erect shaft, giving him guilty pleasure like none he'd ever felt before.

Sora couldn't believe this was happening. He wanted oh-so-badly that this was Kairi doing this, and knowing it was Selphie made him feel guilty and wrong about it all. He almost regretted choosing Selphie instead of Kairi to address his dream. Almost. But it felt so good...

Lost in his thoughts, Sora didn't notice his precum was flowing quite constantly now.
"See? Weather you know it or not, you really like this." Selphie said, taking notice of the amount of precum coming from Sora's cock. All Sora could do in response was groan in pleasure as his breathing sped up.
Selpie started moving her feet faster and faster, anxious to bring Sora to a climax. And she was succeeding too, because he was getting close to coming. As much as Sora hated to admit it, Selphie's feet were making him more and more aroused, and he knew he was a mere seconds away from cumming already.

"S- Selpie! I'm about to- I'm gonna.... I'M GOING TO CUM!" Sora shouted between moans, trying to hold it back a little longer.
Selpie responded by moving her feet even faster. "Does it feel good, Sora? I bet Kairi could never make you feel this way! Come on, cum for me!" Selpie ordered with a lustful grin, "Cum all over my..."

Where did Selphie want Sora to cum?
