Umbre whined, bucking in response to each and every thrust. The constant pinching as he tightly gripped her breasts and nipples left her writhing, as if the pounding wasn't enough. The sensations... they were intense, overwhelming. But as she looked down, seeing her sister below her, she grew self-conscious, reddening beneath her fur. She had chosen this of her own free will, choosing submission over resistance... why did her sister's opinion of it matter in the least?<br/><br/>Even as she told herself that, she couldn't get Valeria out of her head. The pleasure was tempered by her mind's inability to let go. Adrian grabbing her, pulling her to her feet, her toes, was what finally broke that train of thought. Her mind was entirely focused on Adrian once again.<br/><br/>She squirmed out of shock, letting out a gasped "Ahh!" as his grasp tightened around her. Her breasts were subject to even more abuse at his hands, pressed, squished, tugged. She was light, light enough that Adrian could lift her without difficulty, and some of his thrusts were strong enough to actually lift her off the ground, her weight pressing her down onto his shaft and taking him even deeper.<br/><br/>Valeria was gone; she may as well have never existed at all. All that was left was the moment. Thickness inside her. The kneading of her breasts. That hot, hot breath on her shoulder. At first, it felt alien, shameful, but there was no way she could deny the pleasure now.<br/><br/>Neither could Valeria. With Valeria's weight off her, she thought she could manage to wriggle out from beneath the pair and come to her feet, but she hardly had the energy for it - and, she mused, Umbre's terrible massage hadn't helped either. She didn't want to think about what was going on above her, and finding little things to latch on to, even criticisms, seemed to help that. Still, as hard as she tried to, there was no way to shut out the sounds of Umbre's pleasure. Her thoughts turned to self-pity now, dozens of "if only" scenarios filling her mind. If only I was stronger. If only I was more clever, more intelligent, faster, tougher. Her hands balled into fists, tightening around tufts of grass, nearly ripping them out of the ground. She would give anything to stop this horror, anything, but she was helpless. Weak, frail, tired, sore.<br/><br/>Umbre could feel something changing with Adrian, subtle changes in his body, the way he moved, his breathing and heart rate, even those faint smells of sex that drifted past her nose. She reddened, realizing full well that those scents weren't only his, that her body was reacting just as much. Could he tell, though? She kind of hoped he couldn't.<br/><br/>One of his hands moved, and she certainly didn't need to spend a lot of time wondering what he was doing with it. The sudden pinch in her most sensitive area triggered a loud wail, part surprise, part pleasure. At the same time, she felt his shaft leaving her, then the spatters of his seed. She was breathless after her wail, her body still tense, begging for more, begging for a climax of her own.<br/><br/>At Adrian's command, she looked down at Valeria, at the creamy semen across her lower back, butt, and tail. Seeing her sister like this send her mind into lock-down again, embarrassment and humiliation filling her head. "I..." she sputtered, as she knelt down. "Lick it...?" She touched the sticky mess with a finger, lifting it to her nose to smell it. So this was his... it didn't seem like it would have an objectionable taste, but....<br/><br/>"A reward, but, I, please..." Her speech was just a jumbled mess now, much like her mind. Valeria insisting that she refuse, Adrian urging her forward. Her own desires... to not get hurt, to protect her sister. And that reward... that reward burned at the back of her mind. It could be something frivolous, but knowing him....<br/><br/>"I can't, not like this, please understand..." Umbre finally said, turning around and embracing Adrian around the waist, pressing her head against him, letting his cock rest between her breasts. "Please, I just... forgive me..." Shame had won out. She couldn't do it, reward or not. She couldn't lick his sexual fluids off her sister's butt. Her brain was seizing up, refusing to allow her to even if she wanted.
