It was the beginning of the fourth week on the island, Lucy and I went for a walk along the beach.

“Paula has run out of pills.” Lucy told me abruptly. 

“Controception?”

“Yes. She wants to know what to do.”

“..and she asked you?”

“She asked me to ask you.”

“Why me?”

“You knew how to build the shelter, catch fish, and stop us from eating poisonous plants. You're our leader.”

“I thought it was you.”

“It's you. So what will we do when contraception runs out?”

“You don't know?”

“You want to fuck Paula, keep fucking her. Don't you?”

“I do.” 

“More because she could get pregnant. What about John?”

“We have two options, we go back to our own partners, what about Lily who has no man? We continue as we are and don't know who is the father of your child.”

“My child?”

“Your contraception will run out.”

“So if we continue as we are…” Lucy stopped and looked at me. ”..I could have anyone's child.”

“You could.”

“That doesn't bother you?”

“Does it bother you?”

“Who would look after it?”

The mother would breastfeed it, everyone would look after it.”

“You have had this planned.”

“I knew that if we stayed, contraception would run out.”

We walked on.

“It could be a problem.” Lucy mused. “They may have a different idea.”

“You tell John you have no contraception and fuck him.”

“If he fucks me he can't object to Paula.”

“...and Paula wants to continue to have us all.”

“How do you know?”

“She asked you if I could father her child.” 

She stopped again and held my hand.

“Fuck her, keep fucking her.”

“Take Paula to clean the spring. I will meet you there.”

I made the climb to the little spring and found them cleaning it.

“Hello.” I said as I approached. 

“Tony, we have been talking.” Lucy said, laying on a blanket sweeping leaves out of the spring.

I sat on the end of the blanket with a hard cock.

It was Lucy who broke the silence.  “Paula has stopped taking the pill. When you fuck her you will stop when you cum, no working it out by trying to cum again and I'm not going to lick his cum out of you. Keep his seed in you, where we all want it, if he wants more he can have me.I can't eat you after, but I can eat you before he gets his cock in you”

I knew it would be weeks before Paula would become fertile but I played the game and watched the two women munching.

My cock was hard when I arrived just thinking about fucking a fertile woman, now Lucy was giving her blessing to me and Paula. I knew it was a deal, she would be taking spunk from everyone into herself,  every little swimmer would soon have a chance of finding her eggs and growing into a child. 

There were moans from both of them. I did not know who was the most excited about making babies. 

As Lucy moved away, I took her place and kissed Paula.

“Do you want to have my babies?” I asked Paula. 

“Yes, yes I do.”

“Give her babies.” Lucy encouraged us both.

My fingers played with her wet, hot cunt.

“Fuck me, give me your seed.”

How could I refuse her? I slid my desperate cock into her and began to move. I knew that when I came I had to leave, leaving my seed safe and deep in her to swim where they may.

“Oh fuck me, please fuck me.” She sighed in my ear.

“I am , I will again.”

“Oh please forever.”

That made me feel even harder. Paula was cumming constantly, her body lifting us both. I jetted into her and she held me to her. 

“Don't pump it out.” Lucy warned me.

“Leave it there.” Paula asked.

I was laying on top of her supporting myself on my arms, I could feel the heat of her body and breathe even those few inches from her. We were both breathing heavily. I was reluctant to move off her, and forbidden to move in her.

Eventually I moved.

“Thank you darling.” Lucy kissed me, then more passionately kissed Paula. “Come back for more whenever you wish.”

I turned to Lucy and took her. I raked her cunt. I pounded her. I filled her. It was like the first time she had a gangbang. I was thoughtless, but she did cum.

“I think you enjoyed baby fucking Paula.” Lucy whispered softly in my ear.

“I did.”

Paula was laying on her back with her knees up and together,  her feet on the blanket. 

“That was heaven.” Paula claimed.  “You really are OK with this.”

“As long as you are OK with me having John's babies.”

“How will we know?”

“Why should you know?” I contributed. 

“There is no reason here. This is paradise.” Lucy claimed. 

“There are no rules, just our own.” I added.
