Without a word I sat up and threw my leg over him until I was straddling his hips. He gulped as he watched me guide his cock home. Home to where he came from. Where he was born from.
The head of his cock pierced my lips and slid in with ease. God he was big! My mouth had not prepared me for how big it felt inside.
I moaned a sigh of content as he bottomed out. His head nuzzling against my cervix. We fit together perfectly. Like it was destined to be. And we never would have known had we not found ourselves here.
‘Let me know before you cum,’ I told him.
I rocked back and forth on him, feeling ever inch slide in and out of me. Every inch of my son’s cock. Even with how much our relationship had changed over the past few days, it still felt so dirty to think about. A mother and son locked in an intimate embrace. It went against nature. Yet nature led us here. Our urges too strong to ignore.
He reached up and grabbed my bouncing breasts, kneading and massaging them. There was no doubt in my mind that he wanted this as much as I did. He was rock hard inside me and his hands grabbed greedily at my chest.
Our fire burned low as we fucked in the growing shadows. The cave echoing with the sound of our bodies slapping together in unbridled incestuous lust.
My moaning became louder and more desperate as I grew close. Just a few weeks ago I had felt so embarrassed to think that he had heard me moaning as I masturbated in private, now I didn’t care how much of this side of me he saw.
I shuddered as my orgasm crashed over me, letting out a cry that would surely scare the birds into the night. My pussy convulsed around his cock, pulling him deep into me.
‘Oh, fuck! I’m going to cum!’ He gasped.
On shaky legs, I pulled up off him just as his cock erupted, splattering the ground around him and his stomach with gooey white ropes.
I collapsed down onto the ground beside him. My legs still felt weak. My pussy yearned for more. It had felt like I was robbed of my orgasm. I wanted his cock to stay deep inside me as I rode my waves of pleasure. But it was better to be safe than sorry. I had no birth control out here.
He sat up and looked at me. Something seemed different about it. It wasn’t like a son looking at his mother. Nor was it the stolen glances of lust from when I lost my shirt. It was more like how you would regard a lover in the afterglow.
‘That was amazing!’
I shuffled over until our body’s touched and collected the cum from his stomach with my finger.
‘It was for me too,’ I said, licking my finger; tasting his sweet cum. ‘I really needed that. You’re not the only one who gets that horny.’
His smile grew in the dim firelight. ‘So we can do that again?’
I scooped up a small bead of cum that leaked from his cock head and brought it to my mouth.
‘As often as you want.’

Our relationship certainly changed after that. We were no longer mother and son, we were lovers. To my delight, a wall seemed to fall between us. We became far more open about our sexuality, unafraid to speak in depth about our own and the other’s body.
