>Pinkie Pie stayed there, stunned, for a second.
>Her brain was surely processing your words.
>She didn't react, when you pushed your cock inside of her for the first time.
>But as your words finally hit her, she left out a loud, deep, exalted moan, arching her back just a tiny bit and staring up at you with lust and love.
>Her hips starting to roll up against yours, on their own, beaconing you to do what you knew you had to.
>And you did. Slowly, with love and passion, you started to thrust, to massage your mother's inner walls with your rock-solid shaft.
>And she was, herself, massaging your shaft with her inner walls, clenching teasingly around you, then letting go, giving playful giggles.
>She obviously had a lot of practice.
>She gently pulled you down and locked her lips with yours, moaning into the kiss as her tongue began to softly dance with yours, coiling and poking, leading you into a deep French-Kiss.
>You knew the French Tongue was the Tongue of love, but only your mother could make it the Tongue of Your love.
>You both began to pant into each-other's lips.
>Your hips began to thrust a little faster, a little stronger.
>You were but a virgin just a few minutes ago, but you somehow managed to find Pinkie's G-spot, and started to press your cock's tip against it, gently, yet strongly, every few other thrusts.
>It was driving her crazy, making her clench around you only when you'd press over this magic button.
>You had no idea how you could know it was there, the remainings of your 9-months stay within her, perhaps?
>But as you broke the kiss, the whispered in between moans.
>"N-Nonny...~! I-I'm glad... To be your m-mommy..."
>You held her close, kissing her neck and starting to thrust harder, as her legs wrapped around your waist, locking you into her so you'd not pull out at any cost.
>You didn't want to pull out anyway.
"I'm... I'm happy to be your son, Mommy...!"
