He leaned in and kissed me passionately. I could feel his throbbing cock nudging against my pregnant belly. Our tongues danced until my head spun and I couldn’t take it any longer.
We broke away and I grabbed his hand, leading him to the rocky shore. He knew. We wasted no time after climbing out before I was on my hands and knees and he was behind me.
His cock speared into my wanting lips. His hips rammed into my ass. The head of his cock nudged at the entrance to my swollen womb. My first child fucking me while I was pregnant with my second. His child.
I moaned in time with his thrusts. Each moan louder than the last. This was our island. I could be as loud as I wanted. To shout out to the world that my son was fucking me.
His hand caressed my belly as his other squeezed my breasts. So large and full. The things that had started all this. My beautiful breasts teasing the desire in him.
‘Oh fuck, mum!’ he moaned as I pushed back into his thrusts.
My giggle came out in bursts around his thrusts. ‘I told you to call me Susan.’
He grabbed my long wet hair and pushed it over one shoulder. I turned back to look at him.
‘I know. But it’s so much dirtier to call you mum.’
I moaned in agreement as he leant over my back and kissed me. I kissed him back passionately as I almost fell forward from his weight on me.
He straightened back up and grabbed my hips. His face contorting in pleasure. I was lost to my own desire, my moans far higher and quicker.
With one final thrust he erupted into me. Spurt after spurt of his thick ropes splattering against my insides. So long ago I had denied this very feeling, letting his seed spill out over the cave floor. It was where it was meant to be now.
I balled my fists and my toes curled as my own orgasm crashed over me. My legs twitched as every nerve cascaded into ecstasy. My pussy convulsed around his cock, milking every last drop into me.
Finally, his deflating cock slipped out of me, bringing a pool of cum with it. I lay back on the rocks, relishing in the afterglow. His cum leaked out of me, getting stuck in my wild tangle of pubic hair that had grown so uncontained.
He laid down beside me, his hand rubbing over my belly as we caught our breath.
‘I’ll miss this when you give birth.’
‘Miss what?’ I asked.
‘Cumming in you.’
I gave a laugh. ‘Oh sweetie, don’t you worry, that’s not going to stop any time soon.’
He lifted himself up onto his elbow.
‘You’ll get pregnant again, though.’
I took his cock in my hand and gave it a squeeze.
‘And maybe I want that. I want you to give me as many babies as you can. There’s plenty of food on this island. We could support a whole family here.’
He smiled back. ‘I’d love nothing more than to start a family with you.’
Our lips met once more. Kissing not for frenzied passion, but a lover’s embrace.
