Iwaizumi and you started dating in high school, and got married right after college. A lot of the times, he wasn't home. Due to being the athletic trainer for Japan's pro volleyball team. Most often, you didn't mind. But, when he missed your anniversary for work, after he promised he'd be there, you couldn't help but argue and fight with him when he eventually returned home.
It was a couple hours after your argument, and you were sitting in bed, reading a book. Iwa walked in, and didn't say anything. He just crawled under the covers, right up to you, and began going down on you. He always did this. Ever since your first time together, this is how he'd apologize after every argument and fight.
"I'm sorry Baby." He whispered against you. "Please, forgive me." He whispered, as his tongue swirled around a sensitive spot.
