Remember what Sarah's mouth can do

You remember how Sarah’s easy, dirty way of speaking shocked and awed you from the very first night you met her.

Sarah was laying face down on a yoga mat under the pavilion a few hours after you had fucked her laboring pussy. She was coaching Rachel through giving birth to your baby.

“Hah, hah, hoo,” the girls breathed steadily. Rachel was facing you and Sarah, sitting on the mat with her legs spread wide, leaning back on her hands. Her round baby bump dominated her small body, forcing her to pant and cry out with each strong contraction.

You were holding yourself over Sarah, reading the word “INSTRUCTOR” printed on the back of her uniform. You fucked her pussy from behind as she watched Rachel labor, your hips bouncing on Sarah’s soft ass with every thrust.

“You did this to me,” Rachel said, as she panted with effort like you, both absorbed in your own tasks. Rachel’s small frame clarified her statement with another contraction. She noisily breathed through it in time with Sarah.

“Yeah, I did,” you agreed, staring at Rachel’s pregnant body as you fuck Sarah harder, deeper, squishing her ass against your much narrower hips. Her pussy seemed to squeeze your cock inside her every time you tried to pull out, like her body wanted you deeper. Sarah chimed in:

“Yeah, he put a fucking baby inside you, where it belongs. How does it feel to give birth to this boy’s baby, slut?”

“Hah, you know what it’s like, bitch. Like a warm fuzzy feeling, but really hard work, too. Hah, I couldn’t imagine - haaaah - wanting to get fucked while this is happening.” Rachel cried out, her laboring pussy starting to spread open.

“It feels so good though! I can’t wait to feel Eric fuck me when I’m pushing out his baby. My body really likes him. I can feel my tits and my belly aching for it. I always know when a man’s baby will feel good inside. Oh! Keep going, you’re doing great!” The head of your baby was poking out of Rachel’s stretched pussy. Your cock was getting even harder at Sarah’s words. You weren’t sure which one of you she was talking to.

“Fuck, Sarah, I can’t hold on when you say that stuff!” You panted. You were getting close unreasonably fast, and you wanted to last longer this time than you had been that night.

“You’re not supposed to hold on, you’re supposed to dump hot cum inside me and knock me up!” Sarah replied. She purposefully squeezed you with her cunt muscles while laying on the mat like she was just letting you use her. In front of you, Rachel screamed, her belly visibly shrinking inward as her contracting womb finally pushed your baby’s body out between her legs.

Rachel picked up your baby, instinct guiding her to cradle it, hunched over and panting, her pussy gaping wide. Watching Rachel hold your baby, you felt the joy of becoming a daddy combined with the sheer pleasure of Sarah’s greedy cunt milking your cum into her baby room. It was the first time your genes mixed with hers.

Since then, you've kept seeding her and it's still just as rewarding for you as it was then, if not more. She's taught you so many things. You just wish you could have full ownership of her womb. Sarah wipes her flushed face with her towel, her cunt still visibly aroused from your tongue. At least for tonight, she's all yours.
