For one thing, harpies could open their mouths fairly wide, so taking his entire cock down her throat was no problem. Also, Besla had learned a thing or two about the delights of oral sex, and was quite addicted to it. And she could do something that no human female could. With Robbie's dick completely immersed in her mouth, she wrapped her nimble tongue around his shaft and started to stroke it.
Robbie's brain was ringing like a winning pinball game. She was basically giving him a tug-job AND a blowjob at the same time! It was the most incredible thing he had ever experienced. Her strong slimy tongue was easily as talented as any hand, and her mouth was so warm and so inviting. He didn't know what he would be able to do to match that. So he just started licking her pussy with as much speed and ferocity as he could muster.
Besla was pleased. Normally those she mated with blew their loads before thinking of providing her pleasure. This lycanthrope's oral attentions were quite vigorous and pleasing. Then, she felt his tongue tease her rectum, and her eyes shot open. So many earth men were somewhat squeamish about performing such an action, but she had an affinity for it. Of course, she had been informed that she was a bit overly amorous or, in human terms, a total horn-dog. But Robbie seemed to have to qualms about teasing both her opening with his slick tongue. She had chosen her lover well this time. She clawed the ground on either side of his hips as her mouth and tongue continued their work.
Robbie was trying hard to keep up. He sometimes had to push Besla's tail tentacles out of the way so he could stimulate her asshole, then decided to concentrate on her vaginal opening. So he thrust two fingers into her ass, noticing the pleasurable moan it caused, then started licking her slot. Harpies had very tight outer labia, but their inner labia were almost non-existent. Their clits were hidden a little deeper than he was used to, but he managed to find it and attacked it directly.
But try as he might, he couldn't hold out against her attack. Her tongue was stroking his meat in her mouth, and he erupted with little warning. But she took it in stride, swallowing pulse after pulse of jizz at it flowed into her mouth. She drained him dry, at least for the moment.
“Most satisfactory," she mumbled, letting his softening member fall to his belly.
Robbie kept going, licking, poking and ravishing anything he could find that brought Besla pleasure. She pushed back against his face, driving his tongue deeper into her willing sex while he shoved his fingers deeper into her asshole.
He learned something that night. When a harpy female is about to reach orgasm, her tail entraps her partner by coiling around him (or her) and keeping them in place until their moment of rapture passes.
So Besla's tail tentacles wrapped around his head and wrist, securing them where they were and ensuring her release.
Robbie was feeling a Little claustrophobic, but stopping never crossed his mind. When she came, her tentacles constricted and he was afraid he might drown. Luckily, harpies didn't have overly Liquid orgasms, and mostly he just got an up-close-and-personal look of her powerful pussy contracted and quivering.
"You are . . . most talented," Besla purred, licking his cock. She wanted it hard again. She wanted more.
“You are not done, are you?" she asked.
“Are you capable of more, or do you need a nap first?"
While she hadn't meant it to, Besla's comment had tweaked Robbie. His manhood had been challenged, and he had to rise to the occasion. So to speak. He pushed her off of him and got on top of her, kissing her deeply. Unfortunately, he didn't know that Besla HATED being on bottom, so she rolled the pairing over, but kept the kissing.
One of Robbie's hands found his lover's breasts, while the air was latched onto her ass. He continued the roll until he was on top again. He didn't know what game she was playing, but he was determined to win this time. Then he felt her rolling and found himself on bottom again. But his time, it was only briefly, as the two lovers-turned-sparring-partners had encountered a small problem.
It was called the edge of the hill.
The two managed to hold onto each other as they tumbled about twenty feet over rocks and small bushes until crashing into a boulder.
Luckily, both of them were basically unharmed, barring a number of scratches and bruises.
Besla had become incredibly aroused. Her hormonal levels were at an all time high, as both her sexual and combat-related systems were in full swing now. She stood up, pulling him with her and shoved Robbie against the boulder, kissing him more as she ground her body against his.
Robbie was hard as the rock he was getting shoved against. This harpy was a total freak! He grabbed her by the hips, lifted her up and shoved her down on his rigid cock. He took a step forward and allowed her legs to wrap around him. He was roughly groping her ass as he started to pound her. He even started to tap into his animal side. He felt his hair grow a little coarser and his muscles swell with adrenalin. He wasn't going turn into his wolf form. He just wanted to fuck Besla like an animal.
Besla heard her mate growl and noticed with some glee his now inhuman tempo and power. She smelled both the human and the animal in him, and found the scent intoxicating.
"Harder!" she cried.
Robbie obeyed, but only because he was headed that direction anyway.
In the background, a coyote howled as if in appreciating for the fact that his lupine brother was representing in a big way. The slapping of skin seemed to carry out across the desert.
