"Whhuuhh," Ann Marie panted, her ass starting to move now. "Ohhhhh wow, you big son of a bitch!"
Gayle felt something hot trickle down the inside of her thigh. Only then did she remember that she was naked under her robe. Her poor little cunt was overflowing with sex juice. Watching Ann Marie get fucked really good was making her tingle inside. She couldn't help but wonder about Captain Marvel's abilities. Not that she'd ever dream of letting him do anything like that to her. She was just daydreaming about it. When Ann Marie lifted her feet from the dock and crossed them over the big dog's back, Gayle shivered and thrust a hand under her robe.
"No. I'm not going to let myself get worked up this time." She took the hand away. She'd just let her pussy drip if it wanted to. She had to stop letting her emotions rule her like that.
"Uhh, uhhh, uhhhh, baby, yeah…" Ann Marie was squeezing the dog's middle with her thighs. His big cock was penetrating her all the way now. And the sound it made as it slid in and pulled back was fantastic. It was a juicy, sexy, spearing sound and her aunt's juices were running out of her as her excitement grew more intense. Her body whipped around on the dock as the dog fucked her. Her ass bounced up and down against his instinctive thrusts. She was taking everything the Great Dane had to give and seemed to want more! Gayle wasn't as disturbed as she had been a few days ago by such carrying on but she was still shocked. To see her very own aunt take on a dog! It was no wonder she'd switched from men to this Great Dane. How could any guy compete with that kind of cock?
"Nhhuuh, ohhh shit, I'm gonna come… ohhhhhhh Christ!"
The dog chewed gingerly on one of Ann Marie's tits as his haunches shoved and quivered. His throbbing prick looked very raw and swollen as he pulled it all the way out of her and rammed it deep again.
"God, it's a wonder that thing doesn't split her in two!" Gayle felt her own small twat twinge. Just to imagine that huge thing stretching her immature muscles frightened her. It had hurt bad enough when Prince had fucked her.
Ann Marie was twisting and pumping, her white ass dancing erotically in the moonlight as she let the huge dog skewer her with frenzied thrusts. Gayle held her breath, leaning forward from behind the tree to see it all. The dog's whines had become crazed now and he was clawing the dock with his hind paws for added power. His cock was a blaze of slick, tumid meat as it jerked back and speared forward. Full force, it pushed Ann Marie's ass along the dock a few inches at a time and the dog held it in her as she writhed around the stiff stake.
"Ohhhh, you bastard! Ohhh here I come!"
She kicked both feet high, flailing the air, her fists banging the dock. Then she hugged the huge dog down against her as her ass pumped convulsively. Gayle could see that the Great Dane's prick was in to the hilt and that her aunt's cunt was squeezing down tightly around the base. Holding him in her like that, Ann Marie squirmed and wiggled in ways Gayle would have thought impossible. She knew she had never been able to move like that! It was a hurried frenzy of raw sex and the pleasure exploded inside Ann Marie, making her scream, then choke as her delirium grew too intense.
"Ohhhh faster… ohhh, you naughty dog! Ohhhh how you can fuck me!"
The dog's cock was curved slightly upward now as it reached its peak hardness. It looked like some strange creature and again Gayle imagined her hand around it, thought of rubbing it against her pussy. How could such things drift into her mind? She had hated herself for being so impressionable.
"Whhhaaahhh!" Ann Marie screamed, twitching as the final spasms took her up. Her heels dug against the dog's furry back. He rammed her with the full length of his prick now and Gayle heard him yelp as the white froth appeared at the edges of her aunt's pussy. The dog was still fucking as the white strings dangled and fell plopping onto the dock. The dog's balls also were shiny with the cream and it leaked off the edge of the dock as more of it was forced out of Ann Marie's tight cunt. For an instant, Gayle saw her aunt's clit. It was standing like a tiny finger. Even in the moonlight she could tell that it was red and raw and glistening with cum and cunt juice. Her aunt was coming! Coming good!
Gayle gathered her robe around her and started running back through the trees. She didn't see the exposed root. She only remembered tripping and falling forward. Her head struck the trunk of a small tree and she saw a bright light explode against her closed eyelids. Then she saw or heard nothing.
CHAPTER SEVEN
Gayle was awakened by a hot tongue. The tongue was wetting her ass. She knew instantly it was a dog's tongue, and as her aching head cleared somewhat, she knew what dog.
"Captain Marvel!" Gayle cried out in astonishment.
Shakily, Gayle pushed herself up on her hands and knees. What time was it? Where had her robe gone? Then she saw it, a few feet away in the grass. The dog had probably stripped it off her while she had lain unconscious in the grass. The moon was closer to the horizon now so she knew that two or three hours had passed. The beach was empty. Captain Marvel's hot tongue wet her ass cheeks again, spreading them so he could wet her small, tight asshole. With a small cry of fear, Gayle realized she was all alone out there with this awful dog.
"Now you be a good boy and let me get my robe on and go back to…"
Captain Marvel growled as she reached for the robe. He went back to licking her ass. The hot wipe of his tongue was extremely disturbing. Gayle tried to think. If she could just get up and run, if she could make it back to the house. But she knew that the huge animal would drag her down before she got even halfway.
Before she could make a plan, the Great Dane mounted her from behind, his huge jaws closing down on her neck just as Prince had done that first time she'd known a dog cock. But now this dog was pressing his hot, slick cock up against another hole! Panting with surprise and fear, Gayle tried crawling away. His teeth held her, made her wince with pain. Then he drove his belly up her ass, his cock nudging her asshole.
Her ass was all wet with his spit and the smooth knob pressed her muscles apart. The sensation was disgusting at first but when she found she couldn't escape, when she knew that the dog was going to have his will, her disgust turned to panic. Gayle knew that she was relatively small and that this huge canine had a cock as big as a night stick! Already her tiny asshole felt terribly stretched and only his cocktip was inside her.
But it didn't take long for her to know what an ass fuck was like. With a growl and a great lunge, Captain Marvel skewered her at least three inches. His prick surged inside her ass, stretching her hole to make it fit. Whining with fright, Gayle felt the strange tingles spreading. But a girl wasn't supposed to get excited this way, was she?
"Nhhhaaah, ohhhh God, it's so weird!"
Yes, it was weird for her, but for the Great Dane it had to be good. He was making growling sounds of satisfaction deep in his throat and his paws hugged her skinny waist as he humped his powerful back up and drove deeper.
Now the heat spread from his cock and she could hear the juicy sound of the penetration as he rubbed the tender place where he'd stabbed her. Yes, she was getting exited. She was drooling, her head hung down between her braced arms. She could feel how tight it was for the dog. When he pulled back and her sphincter muscle contracted just behind the head of his cock, he wiggled furiously as if caught in some lovely trap.
After a few minutes of this, she felt him jerk harder and something hot flowed into her ass. It came in streams until at last a little bit leaked out and she could smell the pungent aroma. Captain Marvel had taken only a few minutes to come. And her body was shaking with pent-up excitement. He'd actually aroused her to the point of wanting more stimulation. But not from any dog, that was for sure!
