Start off gently

"They look amazing," Kazuma exclaimed. This was the first time he had seen a girl's breasts, that weren't from a picture. And now, he would get to touch some. Kazuma reached out for her breasts slowly. He placed a hand around each one, and gently pressed into her soft flesh with his fingers. They felt so soft and warm, like giant marshmallows. His fingers almost felt like they were going to melt into her.

As he was feeling her boobs, Satsuki was moaning in pleasure. "Do you... do you like them?" she asked between moans. "They're incredible!" Kazuma said. “They are better than I ever dreamed of.”

“You…dreamed…about me?”

“Of course, I have,” Kazuma said as he moved his middle fingers over Satsuki’s nipples. After playing with them for a bit, Kazuma moved first face towards her left breast, put his lips around her nipple, and began sucking on it.

Satsuki continued to moan as Kazuma suckled on her. "I thought I was the one who was going to feed."
