A breeze rustles the leaves of a nearby copse and I suddenly look around. I’m nervous at first but now I hope someone is up in that thicket of silver birch, spying on us. I hope they have their dick out, or their fingers in their pussy, using us as their wanking material… maybe even videoing us to put on Redtube later… before sowing their seed in the long grass.

With that thought, the sweet feeling in my loins begins. I pump harder till it builds, holding back from cumming all the time. Now I’m there! One last powerful thrust and I feel the cum travelling up towards the open vent of my volcanic cock. Whipping it out at the last moment, I push my dick between her arse cheeks and fuck them so that my cum projects in a long arc across her back. The first rope hits her shoulder blade, some lands in her hair… the next few spurts have progressively less energy, splash on the small of her back. I squeeze my balls gently and the last drops dribble down my shaft. I use the lubrication to slide my cock across her arsehole, then smear my cum all over her with my hands, like soap. I reach round to massage and cover her tits with it… she loves that. She’s heaving and moaning like she’s about to cum too.

‘Push it in my arse, quick, while it’s hard enough… fuck my arse, make me cum… I’m nearly there…oh, oh…’

I do as I’m told, though I’m only just hard enough to penetrate her. Once the tip is inside I feel her reach down and touch herself and that, despite having just emptied my load onto her, gets me growing again. Up her delicious arse I go and she is coming too… shaking, bucking, crying out, pushing herself back into me as she rubs her clit. I pierce her backside to my full length and she’s pulling and twisting her nipples in turn, sobbing with every cycle of her blossoming orgasm. Now, she too is spent and doubles over, touches her toes, breathes deeply, noisily, still impaled on my stiff manhood. We stay like that till her sighs and my erection subside.

Suddenly she pulls away.

‘Quick! Into the water… right under.’ Again I follow orders. First we stand together, then she takes my hand and beckons me to crouch. It’s unbelievably, heart-stoppingly cold, but when I finally break the surface and clamber up onto the hot, flat rock once again, I feel more alive than ever before. Every single cell of my body feels renewed, regenerated, energised, full of power and life.

‘Next year… every year. We’ll do this every year and never grow old.’ She too is overflowing with life and enthusiasm. We hug and kiss. Wet and naked on our own rock, beside our waterfall we make our pact, repeating the words in unison. Then she kneels before me.

‘Piss on me.’ This is something we’ve never done, not even talked about.

‘I… I’m not sure…’ But she nods her reassurance:

‘Many cultures believe that fresh piss is cleansing, healing, life giving…’ she says, and it suddenly feels perfect, natural. I relax, release my bladder and feel it rise up and warm my now shrivelled appendage… it spurts onto her neck and tits, splashes down her belly,
