"Don't stop," Sayuri begged, gripping on him tightly as she endured the sudden, sharp pain.
Kyle felt intense regret.
Why didn't he consider the possibility that this was her first time?
She had been so pro-active and confident, every action giving him the impression that she was more than skilled in this area.
Kyle's first time had been him basically leaving everything to his spouse, and he had been so embarrassed exposing himself in front of his spouse that he was basically a statute.
No, not a statute, but a puppet. Being controlled under the act of his spouse.
Even if Sayuri did learn all of this as a ninja, the natural way she acted made him believe that it wasn't her first time.
He felt regret because he would have been gentler so that the penetration wouldn't have hurt so much.
Kyle kissed her deeply as he allowed her to adjust to his size and the sudden invasion at her core.
