Tell her the truth

"You know that little clamshell with the little pills in it?"

"Yeah... thats my birth control... why?" she says between bounces.

"I replaced it with a fertility ****" you say as a grin slides across your face.

"Oh god..." she moans and a gush of fluid runs out of her coating your groin with her sticky mess. "You wanted me to get knocked up..."

You nod.

Her hands squeeze at her tits, "You wanted my tits to fill up with milk..."

You grin and nod some more.

"You dont care if your little sailors find their way inside of my secret place... find my poor little egg... cover it and rub against it over and over until it invites one inside..."

You groan loudly as your balls contract shooting your seed straight up into her thirsty womb. Spurt after spurt hammering away at her cervix. Lizzie screams loudly as you breed her "against her will".
