She crawls up between his legs and leans over him. She presses her torso to his and looks into his eyes. She can feel his hardening cock pressing into her stomach. He is tired and weak, but he meets her gaze and holds it. She brings her face close to his, until his beard tickles her chin. She takes a deep breath in and tastes his essence. His chest rises underneath hers as he breathes her in in return.
She plants a sweet kiss on his lips and reaches under herself and firmly grabs his cock. His lips lightly press back against hers. She sits up between his legs once more, taking a good look at him. It looks like this man has lived through a few rough winters. She runs her free hand over his muscled torso which is knotted and pocked by scars. She can't help but to tangle her fingers in the thick reddish brown hair on his chest and give it a little tug. He bares his teeth and a hiss of breath escapes his lips. His whole body is covered with hair, almost deer coloured. It grows thick on his chest, running in a line down between his legs. His stomach and thighs are dusted with it and it thickens again on his forearms and calves. Even his fingers and toes have visible hair growing on them! She has never seen anyone with this much hair, let alone such an odd colour, and finds herself fascinated. The hair on his head is thick and long and his beard is red as flame. It is very strange to her, but she's intrigued. His hair is reddest at the base of his penis, which she finds most intriguing of all...
All the while she has been stroking his cock and it is fully hard and hot with blood now. His eyes are closed and he is breathing steadily. His skin is all a healthy pink colour, but she decides she will take it easy on him tonight, for she has a feeling the snowstorm will last for a few days. She had stocked her cave so she would have provisions for weeks. A little less with a man to feed, but he could find a way to make it up to her. Of course, he could probably use something to eat right now...
She got up and climbed over him, straddling his chest so her pussy hovered over his face. She started stroking his cock and his hairy inner thighs. She took his large balls in her hands and fondled them, lightly squeezing them. He quietly moaned. His cock is staring her right in the face now, and she can only resist it for so long! She grasps it at the base with one hand and places her other hand on his inner thigh, applying some pressure on his perineum. That gets another moan out of him! Finally she takes his cock into her mouth and moves her lips up and down the shaft, letting some drool run down to the base. She spreads her saliva up and down his penis with her hand, making a gentle twisting motion. She circles around the head with her tongue, running it over the slit in the tip. Another moan!
To her surprise and relief he raises his hands to her waist. He begins to rub her all over her thighs and her hips. He squeezes her ass, spreading her cheeks and baring her cunt to him. She pushes her hips back into his hands, wiggling her ass in his face. At long last, he pulls her hips down so she is sitting on his face. With him now enthusiastically licking her pussy, she begins to suck him in earnest. She takes as much of him into her mouth as she can and he begins to thrust up to meet her. As he thrusts deeper and harder into her mouth, she feels herself losing control. She is grinding herself on his face with vigour. The stars begin to rise in her vision and she starts to shake. He wraps his arms around her trembling hips and holds her tight to his face as she comes. She has to release his cock from her mouth so she can breathe. Her orgasm seems to last forever. Eventually she rolls off of him, panting and exhausted. He rises to his knees above her and strokes his cock. He gently lifts her head and she willingly opens her mouth for him. He shoves his cock as deep into her mouth as it would go and pumps his seed deep into her throat. She swallows it all and smiles at him. He smiles back.
They lie down by the fire, warm and safe and satisfied. This really is as good as life gets for a cavewoman.
