I could feel her body tense, and her pussy tightened around my dick. I held out all too briefly and as her body tremble and she began to scream. I felt myself beginning to cum. I came hard inside of her, never stopping as a I continued to smack her ass and pump harder. She collapsed forward on the bed, her body covered with sweat. I collapsed behind her. She sighed heavily and I pulled slowly out of her savoring the sweet release. I rolled over and reached for a towel and after letting some of my cum dribble out of her, I carefully dried her off. I pulled the plug out of her and pulled her close to me.I kissed her gently on her forehead, letting her know that she had my approval.
