My Unexpected Affair

I recently got divorced after 30 years of marriage and started seeing a younger guy named Jack. We met through a dating app, and the chemistry was instant. Last night, we finally had sex at my place, I hadn't been with anyone but my ex-husband for decades. The sensation of his thick, hard cock inside me felt both thrillingly forbidden and incredibly natural. His fingers dug into my hips as he thrust deeply, grunting with each push. I loved the way he looked at me like I was something precious and untouchable. Afterwards, we lay tangled together, hearts racing. Was this normal? Am I just a foolish old woman who needs to grow up?
