Chapter 1

According to the law, Mommy and Grandpa had sexually abused my fraternal twin sister Molly and me since we were toddlers. Grandpa passed away when we were four. We missed him but didn’t fully understand death, so his loss was less traumatic than it would have been if we were older.

To celebrate our sixth birthday, Mommy taught us to sexually abuse each other too. We were glad Mommy took special pills so she could still breastfeed us. We wouldn’t learn ‘abuse’ usually meant something bad until we were 17. We had always loved it.

After Molly and I blew out the candles on our 14th birthday, we ate cake and drank milk fresh from Mommy’s nipples. When we finished, she masturbated us as we watched our first porn movie to celebrate. We were inspired to lick, kiss, and fondle every bit of Mommy and each other several times. When the movie was over, Mommy put on a robe and reminded us, “I need to do my exercises with Charlie and Robert. I’ll see you in bed in an hour or so.”

After a sexy shower with my twin, she took my hand and led me to the bedroom. It felt great when Molly would lick and suck my penis, and I made her very happy by licking her slit and sucking on the edges, especially the little bump at the top. She was still a virgin, so I couldn’t get my tongue or fingers in her very far.

Neither of us was developed enough to climax, but we were quite happy. I was getting sleepy and decided I’d had enough. I moved my penis and lower body away from Molly’s face, but she wanted me to keep going. I kept licking her little pussy, since we loved each other very much and she always made me feel great. Not long after, she had enough too. “Oh, Michael, I love you so much!”

“I love you too, Molly!” I moved around so our faces were close together. She kissed my lips and hugged me tightly. I played with her long blonde hair and rested my cheek on hers. I told her, “I know you like to wait until Mommy climbs in with us before you sleep, but I’m so tired!” I yawned, reinforcing my point. “Let’s just go to sleep.”

“Okay, brother. Good night.” She rolled over with her back to me, and I spooned behind her like always. I rested my dick between her thighs and put my hand on her chest. I was looking forward to her having boobs like Mommy. Mommy’s big ones felt so comfortable and nice.

One morning I went to the bathroom nude and peed like always. I was a little disappointed Molly wasn’t there to aim for me. The times she did that were fun. Molly met me in the bedroom when I returned. She had a tummy ache and didn’t want to do our usual wake-up loving. I was concerned for her and rubbed her belly where she wanted me to. I dozed off again fondling her tiny breast bumps. I woke up alone in bed again.

When I got up I walked to the dining room and saw Mommy eating an omelet and toast. “Is Molly okay? Where is she?”

“Today is a big day! Molly’s having her first period!”

I smiled. It was one of the most important days of my life. I could finally start to prove my love for Molly, and I could prove my love for Mommy when she had her next period too! And they would prove their love for me as soon as I could ejaculate!

Mommy home-schooled us, and one of the first things we learned were the essentials of life. A person needs air to breathe, water or other liquid to drink, and food to eat. Also critically important, humans need exercise, sleep, and companionship.

Good sleep is one of the hardest needs to fulfill. You need a safe, quiet, comfortable place, and you need to fall asleep happy. People that love each other make each other’s bodies happy, so they can sleep well.

Kids run around and play, usually getting plenty of exercise, but it’s harder for adults. Adults are a lot more likely to get enough exercise if it’s something fun, so Mommy did her push-ups, sit-ups, and hip thrusts on top of our butler Robert or gardener Charlie. I couldn’t wait! With Molly being old enough now, I’d get to help her and Mommy exercise soon!

Having friends to talk to is enough for companionship, but love is SO MUCH better! We’d be able to finally prove our love! The next time Molly needed to go to the bathroom, Mommy taught me to prove my love for her by taking care of her during her period. Since Molly was still a virgin she couldn’t use tampons. Mommy had taught us about periods before, and I knew about girls getting rid of small bits of womb tissue and old blood through their pussies, but I was still disturbed to see the pad in Molly’s underwear had blood in it.

I got a little queasy seeing the blood, but Mommy explained it was the old, worn-out blood that Molly didn’t need any more. She showed me how to wash Molly clean and replace the pads for her. She had told me earlier it was very important that I not complain about it being dirty or unappealing, because that would make Molly feel bad. I was glad I could help my sister, and instead of complaining I tried to cheer her up.

I helped Molly in the bathroom each time she needed to change pads, pee, or poop for five whole days. I felt erections form in my pants each time, which was another reason for me to be happy. I thought it was exciting to see urine or feces come out the openings I would have my penis in soon.

Molly didn’t want to lick or suck me during her period, and I had no appetite for her pussy when blood kept coming out of it. We cuddled and relaxed before sleep, and that was enough.

We returned to our usual kissing and oral sex at night when her period was over and were very happy. When it was time, I proved my love for Mommy by taking care of her period too. It thought it was a lot more convenient that Mommy could use tampons. It felt sexy to put the new ones in her, imagining what it would feel like when I could finally do the same with my penis.

The three of us started going to the bathroom together when one of us needed to pee or poop, so we could wipe each other clean. A person who can see the area is a lot better at getting things clean, and we liked to see and play with each other’s bodies very much. We started taking enemas before showering every night, so we could kiss and play with each other’s butts and poop holes in bed. I greatly enjoyed showing how much I loved them by licking their naughtiest parts, and having a tongue in my butt felt wonderful!

It was another great day when I discovered Molly’s boobs were starting to grow. Molly and I both liked it when I licked and sucked her little nipples, and Mommy was happy to watch. Mommy switched to exercising earlier in the day, so she could spend more time being happy with Molly and I before bed. Watching Mommy and Molly lick my penis at the same time was one of the best things ever! I was happy to have two pussies to lick and suck too. Sucking milk out of Mommy’s big boobs was even better when I could share her milk with my sister.

A few weeks later Mommy was sucking me and I suddenly felt AMAZING! I felt my penis pulsating, along with something inside me. I delivered my first load of semen to Mommy’s mouth. When it finished, I saw her swallow. She sat up with a look of supreme joy on her face. “My daughter’s almost a WOMAN, and now my son’s a MAN! It’s a great day! I’ve been waiting since you were born for this! YES! We need to make Molly a woman and celebrate!” That night Mommy had me lay on my back on a large towel and helped Molly squat above me.

She said, “Molly, you know it will hurt the first time, but after that sex will make you feel SO GOOD! I’ll help you aim. When you’re ready, just sit down on him quick. If you go slow it’ll hurt a lot more. Once you’re sitting on him, just rock your hips to make him move in and out of you. Okay?”
