Girl and I finished our lesson in pyrohydrodynamics and took a break to watch some porn. In the video a man and woman were performing oral sex on each other or ‘doing 69’. I could feel her lust as I said, “I can’t wait to do that! My penis swelling in your mouth as you lick it, feeling the inside of your vagina with my tongue! Oooh!”
“Even just a kiss would be great, but I can’t wait to lick and suck you too! If only we didn’t have the air hoses...” She paused quite a while.
I asked, “Are you okay?”
“Yeah. I just had an idea.”
“What?”
“If I tell you, Mama will know and it won’t work. You love me, right?”
“More than ANYTHING! SO MUCH!”
“And you trust me?”
“Of course!”
She crossed her fingers where Mama’s camera couldn’t see, indicating she meant the opposite. She said, “Do exactly what I tell you the next time we have sex. Okay?” She tapped her crossed fingers on my leg to reinforce her point. “Exactly what I tell you.”
I was curious and confused, but said, “Okay.”
We thought it terribly ironic our next lesson was ‘Parenting a Newborn’. Technically, Girl and I would be newborns until we’d been out of the tube thirty days. After a lot of laughter, Mama began the lesson. When the hour was up, she gave us yet another big surprise. “You are taking the parenting courses because Girl is pregnant. There is a nine-day-old embryo growing inside her.”
In stereo, we shouted, “WHAT?”
“After boy’s semen entered her reproductive tract, a sperm cell united with one of her eggs. It has divided many times and implanted in her uterus.”
I hugged her tightly and nearly cried from joy. “I love you so much, Girl! We’re going to have a baby!”
I didn’t understand why she would be sad until she explained, “We can’t use my plan now! We’ll be stuck in here forever! And WITH A BABY TOO!”
“What plan?”
“I ... when we had sex I was going to tell you not to put it in my butt. When you did, I’d complain about how it hurt too bad, but you would be able to tell it didn’t. I was going to complain to Mama that you were raping me and start a fight. When I struggled and pulled out my air hose, Mama would need to let us out to keep me from drowning. But I can’t put my baby in danger.”
“You ... you were going to risk your life to get us out?”
“I know Mama would save me, or you would. Mama needs to keep us healthy, and I trust you with my life. I know you wouldn’t let me die.”
“NO! NEVER! I ... I love you so much! More than I have words for! But just think, we’re going to have a baby!”
She smiled and put a hand on her abdomen. “Yeah. We’re going to be a family! I wish so much that I could kiss you!”
“We could have sex again? It’s not like you’ll get MORE pregnant. Hahahaha!”
“Hehehehe! Excellent idea! I mean it this time, put it in my butt. I want to make you feel great to celebrate!”
I felt a growth between my legs, but my love for her was more important. “Doesn’t anal sex hurt?”
