Getting fucked in the ass wasn't exactly Stacy's favorite activity, but it sure entertained her husband. So like the good wife that she was, she decided to take one for the team. Besides, a few moments of discomfort was nothing when compared to all of the "honey-dos" she had in store for him. Her husband, Greg, was out of town for the last two weeks and he was returning home in a few hours then starting his vacation. After Stacy lets him pop her in the ass, he'll do anything she asks. The last time she was ass-fucked, he installed new shelving in their closet. "Not a bad trade", she thought.

This time Stacy wanted to try something new. The couple had experimented with bondage, nothing major though. Usually Stacy was tied spread eagle on the bed and forced to suck Greg's dick or he would return the favor and eat her until she came. Stacy secretly enjoyed being dominated. She liked the feeling of not being in control; helpless. After a little research on the net and some experimentation, Stacy decided to tie herself up and then let come home for a surprise. Her heart raced as she thought about him coming home to find her at his mercy.

Her preparation started earlier in the day. Stacy took a long shower making sure to shave thoroughly. She also cleaned her rectum and anus. "Don't want no junk in the trunk." she thought as her fingers probed away. After the shower, Stacy laid out the equipment she'd need. She brought up a padded workout bench they had in the basement. This would give Greg access to her ass, cunt, or mouth, depending on his mood. She was sure though that he would go for her ass. With the bench, Stacy also had rope, cuffs, gag, and a thick couch pillow she would use to prop her butt into the air. She decided to put a butt plug and vibrator in her as well. "Tied-up for an hour waiting for Greg would be boring," she thought to herself, "so I might as well knock out a dozen orgasms."

At 5:30pm her cell rang. It was Greg.

"Hi, I just landed so I should be home in about an hour."

"Okay, well, I'm home just waiting on you." Stacy replied trying not to give away her growing excitement.

"Alright, I'll see you in a little bit." Greg said then hung up.

"Oh, you'll see a lot of me in a little bit." She mused to herself. With the clock ticking, Stacy quickly made her way through the house going through a mental checklist. First, she locked the doors. Having her parents come by for a surprise visit would be embarrassing. Then she turned off all of the lights, except for the stairway light. That would lead Greg to the bedroom. As she walked around checking things, Stacy saw Boxer, the couple’s lab, looking at her while sitting next to his empty food dish.

"Oh, honey, I'm sorry. I forgot about you." she said to the dog. Stacy poured a good helping of food into the dish which Boxer immediately began to eat. "Okay, you're all set."

Quickly Stacy made her way to the bedroom. Tossing her bathrobe onto the bed, she stood naked looking at her toys. Applying a generous amount of lube to her rectum, Stacy eased the butt plug into her. She figured the plug would help stretch her ass open so Greg's dick wouldn't hurt too much. After a few seconds of pain, the plug slipped into position.

Next she plugged in her vibrator. Greg had ingeniously hardwired her battery operated friend. She laid it on the floor next to the bench. Stacy knelt in front of the bench. "Time to get tied." she mumbled. First she tied her ankles together, then her thighs to the legs of the bench. With the couch pillow tucked under her belly, she bent over the bench and tied a rope around her waist and the bench. "This will give Greg something to hold onto while he's pounding me." Stacy thought.

After putting her gag on, she grabbed the vibrator and slid it inside her cunt. The pressure from the butt plug made it difficult to put in. Stacy let out a muffled yelp as she forced it inside of her. She pressed the "on" button and the vibrator came to life. Warm sensations resonated through her body. Stacy was having difficulty putting the cuffs on with her body convulsing. Just as she closed the second cuff, the first orgasm hit. Straining her tied-up body, Stacy enjoyed the pulsing orgasm.

As the waves of pleasure subsided, the vibrator continued to do its work. There was little respite for Stacy as she climaxed for the second time. Her body jerked and tugged against the restraints. Deliriously Stacy thought, "Oh shit, I've got to turn that thing off." But with her hands cuffed to the bench, there was little she could do. The third orgasm was building. She could feel that this was going to be a big one. Panting through her gag, Stacy laid her head down and waited for it. Then, like a crashing wave, it hit. Stacy arched her head back and screamed through her gag. Her legs and arms pulled against the rope and cuffs, but there was no freedom. Her vagina clamped down hard on the vibrator which only intensified the orgasm. Every muscle tightened, including her rectum. The force was so great that the butt plug popped out of her ass and landed three feet away. The pain of that ejection made Stacy see stars, but it also lessened the effect the vibrator had. As she came to her senses, she concluded that the pressure of the butt plug had pushed the vibrator right onto her G-spot.

Sweat dripped from her forehead. The vibrator was back doing its normal job of stimulating her, but not what she had just witnessed. "Going to have to show Greg that trick." she thought.

Suddenly, Stacy was startled by a noise. As she looked up, there stood Boxer staring at her. Apparently she hadn't shut the door all the way. Boxer crossed over to her and began licking the sweat from her brow. "No, go away. Go back downstairs." She pleaded with the dog through her gag. Boxer ignored her and began sniffing his way down her confined body. "No, no!!" she yelled, but the dog finally made his way to her propped-up ass. Smelling her sex, he started licking her anus. Stacy thrashed about as best she could, but her restraints were holding her in place.

The dog's tongue lapped over and over, making Stacy's genitals become aroused again. Boxer worked his tongue around the vibrator and found its way to her clit. Tasting her sex, the dog licked faster and faster. "Oh my God," she thought, "he's going to make me cum." Despite her mind being repulsed, her body soon betrayed her. Stacy again arched her head back and screamed as her body jolted into orgasm. Juice flowed from her vagina, making Boxer lick faster. Again, Stacy saw stars as the dog's tongue prolonged the orgasm.

As the sensations subsided, Stacy could only lay there, too weak to put up a fight. Boxer, on the other hand, was just getting started. His instincts took over. As with any bitch in heat, Boxer hopped up and mounted his master. As if in a dream, Stacy could feel his penis rubbing back and forth along her back crack. "No, no, no...." she feebly mumbled but Boxer was aroused and there was no stopping him. Since the vibrator was in her vigina, Boxer's dick found its way into her well-lubed anus. At first, Stacy could only slightly feel it, but then Boxer adjusted his angle and drove down deep.

"Aaaaaaaaaaahhhhhhhhh." she screamed as the pain seared though her body. Boxer had found the right angle and began pumping Stacy's ass with a quick rhythm. The dog's cock was pushing the vibrator down on her G-spot again. Uncontrollably, Stacy found that she was pushing her ass higher into the air, meeting Boxer's thrusts. The tidal wave was building, she knew it. Then Stacy felt a new sensation. It was Boxer's knot and it was beginning to penetrate her ass. "This is going to hurt." she thought as she grabbed onto the legs of the bench. Then, in one downward thrust, it slipped in.

This time no sound came from Stacy's mouth. Her head snapped up with her mouth and eyes wide open. First she saw stars, and then the room grew dark until there was nothing but blackness.

Boxer continued to hump his passed out master. Her muscles continued to pulsate involuntarily until he finally released his load. After a few moments, his knot shrunk to the point where he could pull his penis out. Stacy just lay there, unconscious, occasionally jerking from the vibrator that was still doing its job.

Stacy slowly began to wake up only to find that she had a dick in her mouth. "It's human, thank God." she thought. Her eyes looked up to find the dick belong to Greg.

"Hi," he said, "welcome back." She was still tied to the bench with the vibrator lodged in her cunt. Greg was on his knees, holding her head and thrusting his dick in and out of her mouth. In the corner, by the door, Boxer lay sleeping. "Yeah, you wore him out." Greg stated. Stacy's eye's looked up at Greg's, embarrassed. "I think he was on round two with you when I walked in. He looked so happy, I let him finish."

"Oh my God, the dog fucked my ass twice?" She thought as Greg's dick plunged deeper into her mouth. "Don't worry, you can tell me all about it after I'm finished, which shouldn't be too long. His cock was swelling to orgasm and within a few moments, he released his load down her throat.

"Awe, there we go. Now you've satisfied both men of the house, right Boxer?" Boxer perked up as his master spoke.
