Hehh, you've caught onto my secret about why I like distracting you with my filthy mouth so much~ Iwa-chan makes a lot of hot expressions when he can't think straight.

[Purring the words and arching his back slightly now to buck up to that bonus of friction, Oikawa digs his teeth into place again and groans softly. Iwaizumi wants to see him without being distracted by his touch, that's why his hands were tied. He wants to see him, watch him, look at him as he starts falling apart and all the way through falling apart and Oikawa thinks that's just as hot as all the things he's doing to him now.

He does like being watched, after all.]
