"Dad...I'm fertile."

"Dad...I'm fertile."

You turn your head and stare at her, you were sure you heard that wrong. You MUST have heard that wrong! She looks back at you, her face a mask of passionate bliss as she rode you to an impending and fast approaching climax.

You were nearing the end yourself. You gasp. "What did you say?"

She whispers once more in your ear. "That box I brought home...it was the pill...I took it...I took it for us Daddy..."

Your eyes widen in shock and horror. That little blue and white box, you'd forgotten about it. 'The Pill' didn't mean what it meant when you were younger. Because 'The Shot' now stopped all accidental pregnancy with one hundred percent effectiveness the birth control pill was a thing of the past. When a woman did want to become fertile she had to take what was now colloquially known as 'the pill'. Not only did it nullify the effects of the shot, it induced ovulation in very short order. The chances of a successful pregnancy after it was taken was very high!

Her breathing was picking up, her hot breath against your ear. "I'm fertile Daddy. I made myself fertile for you." She whispers as she rides you with ever increasing urgency. "I'm gonna have your baby Daddy."

Your mind which had been lost to passion, was now trying to fight it back. You whisper back, struggling to keep your voice quiet enough so Elsie can't hear you. "Penny...no! What have you done? Penny, stop, get off...get off of me..."

You begin pushing against her tight sculpted abs and kicking your legs. You push your head and shoulders back against the headboard. You had to escape. "Penny! Penny!"

In response she wraps her feet in under your legs and bore down with greater power. She grabs your wrists in her hands and slowly but surely powers them down to pin them against the pillows at your sides. As she holds you down she continues her relentless riding. "Don't fight me Daddy...ohhhh god...you're gonna make me cum...you're close too...I can feel it...come on Daddy, let it go!"

You struggle against her but she was stronger and had the top position. She continues to ride you, her tight pussy gripping your manhood as she bore down on top of you in her writhing pleasure.

You fight it, you fight that inexorable feeling, you fight it back with every fiber of your being...

...

...

...

BOOM!

"UGHHH!" Your body betrays your mind and lets loose. You buck and grunt and let out a long mournful groan. "Nooooo..."

Penny shudders on top of you as she is rocked by her own powerful climax. She throws her arms around your body and neck as you both share your simultaneous bliss. Through erratic shallow breaths she gasps. "That's it! I feel youuuuu! OHHHH GOD! Fill me up baby!"

You are uber-conscious of every virile burst you are blasting up into your daughter's fertile young womb. The struggle to fight against each mind blowing pulse intensifying the sensation that much more. She grinds against you as she wanted you as deep as possible as her spasming honey pot milked your every last drop from you.

It seemed like but a moment...it seemed like an eternity.

It is all over and as you begin to relax you see the smiling face of your daughter in front of you, her blue eyes twinkle. "Ohhhh thank you Daddy!" She grabs you by the face and kisses you on the lips. You gaze upon her in disbelief. Your mind reeling at all that had happened.

Keeping you nestled inside of her she rests her body down against yours. Her head coming to rest on your shoulder. She hugs you like a big teddy bear as she just hums to herself in total satisfaction. You put one arm around her. You didn't know what to say or what to do. You were numb.

You look beside you to see Elsie lying there, still watching with those dark eyes. She smiles an exhausted smile at you as you look at her. She looked so alone right now, curled up beside you and Penny as the pair of you embraced. Disheveled, cum stained, used and discarded. You reach over and take her hand. She grasps onto with both of hers and kisses it. She holds your hand to herself like a treasured object. As if she was afraid of losing you. She mouths the words. "I love you."

As you look at her you realize it was 19 years ago that this had happened to you before. That time was an accident...not this time.

Penny sighs as she kisses your chest and says once more in a soft happy voice. "Thank you Daddy."
