I pounded myself into her with a few orgasmic thrusts, feeling the last few jets of my cum go deep inside her, filling her pussy and her womb. Eventually we both relaxed and I collapsed on top of her. My head was resting in the crook of her neck and her limp legs were still loosely wrapped around my waist. I could feel my cock starting to go flaccid inside her tight pussy. I looked up at Jen and we kissed each other softly and gently. She tasted magnificent and felt just as good in my arms.
We caught our breath again, eventually. We looked at each other as Jen said “Oh. My. God. Where did that come from? That was the last thing I was expecting tonight.”
“Me too.” I replied “But you are so beautiful. And I love you.”
Jen smiled the biggest smile I had ever seen her have on her lips. “Awww, brother. I love you too…”
We kissed again, softly feeling how much the love was true.
Jen looked at me again, pausing. “…Bum-face.” She said with a giggle. “I do love having your cock inside me still. It just feels right. Doesn’t it? Is that weird?”
I looked at her straight in her beautiful hazel eyes. “It is a bit weird. You’re my sister. Of course, it feels a bit weird. My cock is still inside my little sister’s perfect, wet, gorgeous little pussy. But it still feels right. So very, very right.”
Jen and I kissed again. Softly, passionately and with love. I was the luckiest guy alive.
