Sara went to answer the ring at the bell dressed in black high heels, high cut black panties, and push up cups under her breasts. She had on a see through wrap around robe that ended in the middle of her thighs. She carried a thin flexible shaft in her right hand, which she whipped experimentally against the air, thrilling to its vibrations as it quivered against her palm. She knew it would be Mark at the door. Josie had sent him with specific instructions.
She opened the door, seeing him standing there grinning. She reached inside his shirt to find the leather collar Josie had promised. She inserted a finger into the loop at the front and jerked him inside. He fell with a crash onto the carpet at her feet. "Stay there," she ordered, placing a foot on his shoulder as he struggled to rise. The position gave him an excellent view up her long legs to her panty covered crotch. "Give me your leash," Sara ordered, and Mark obediently produced a long, thin leather leash, which Sara immediately fastened into the collar around his neck.
Sara led Mark up the stairs, taking her time, flashing her long legs and exposing her black panties to his view with every step up. She sat on the edge of the bed and pushed him down on the floor, twirling the leash in her hand. She placed a foot on either shoulder and swung the whip-like shaft experimentally. A feeling of power was rising in her loins and she toyed with how to exercise it, how to get him to do all her bidding, making her cum while forcing him to wait. "Have you learned your lessons well?" she asked, testing him.
"Yes," he said.
"Yes, mistress," she corrected, lashing him lightly on the butt, thrilling to the sound of the leather shaft across his jeans-covered ass. She smacked him again, harder this time. He winced slightly, but made no move to escape the punishment. "Now, take those jeans off. I want to see your naked ass pushing air."
"Yes, mistress," he said and hurriedly stripped. When he started to take off his shirt, Sara stopped him.
"Did I tell you to take off your shirt?"
"No, mistress. I'm sorry."
"You bet your little ass you're sorry. Now, get back down on your knees and clean my feet." Mark began licking at Sara's feet, running his tongue sensuously between her toes, sucking each individual toe into his mouth, then working his way down the sole. When he hit a sensitive spot, Sara jerked her foot back a little. "Don't tickle," she said, smacking his ass for emphasis. The sound of the leather paddle on his bare ass had a different sound, a different feel, and Sara drank in the sound, watching Mark squirm with pain as his butt cheeks turned a crimson red.
"Would you like to eat my ass?" she asked.
"Oh, yes, mistress. I'd love to suck your ass. Delicious." He licked his lips in anticipation.
"I thought so, but you'll have to earn that right. First, let me see you jack off. I want to see you get hard." Mark immediately began stroking up and down on his cock, feeling it rise to erection as he remained on his knees, working his cock with one hand and supporting himself with the other. Sara watched the cock grow before her eyes, then stopped him, ordering him to lie belly down on the bed with his legs hanging over. "And don't move till I get back," she said, going to her dresser drawer for more toys to tease him with.
She returned with a thick electric dildo with rotating beads buried in its shaft and a realistic looking strap-on model. She fastened the strap-on around her waist and smeared some lubricant on the tip. As she approached the bed she saw Mark had worked one hand under him and was rubbing at his crotch. She brought the whip down hard across both his ass cheeks, smiling as she heard him scream with the jolt, and then she swatted him a few softer blows, raining them down around the red welt she saw growing diagonally across his plump, tight ass. Mark whimpered in pain, then sobbed softly with the gentler proddings.
Sara stood by Mark's face, flexing her artificial man shaft. "Do you like my dick? If you're real good while I fuck you, I just might let you suck it. Do you think you can do that?"
"Oh, yes mistress. I'll be good. I'll suck your dick for you, just like you want it."
"That's better," she purred, feeling the exhilaration growing as he followed her degrading commands perfectly. Josie had trained him well. She moved back toward his upthrust ass, moving between his outstretched legs. "Spread those ass cheeks for me, so Momma can get up your ass and fuck you good." Mark reached both his hands back and spread his ass cheeks wide, feeling his rectum dilate with the pressure.
She moved the strap on smoothly between his cheeks, feeling the slippery smoothness of it caressing him. She poised at the tight entrance to his bung hole, then stabbed into him, plunging the tip into his ass with a grunt. He shook a little, feeling the entrance like a sharp stab, but she held his hips steady and wouldn't let him get away. Slowly she started moving the dildo in and out of his asshole, feeling it press against the sphincter, then suddenly she shoved hard past that barrier, and the dick slid home, deep into Mark's ass. He cried out with a mixture of pain and pleasure, the line between the two having long since obscured for him.
She held still for a moment as his ass expanded to accept the hard rubber cock deep inside it. Then she began pumping, grinding her hips like a man, fucking Mark slowly and sensuously. Just the way she liked it. As he responded by wriggling his ass back at her, she speeded up her movements, fucking hard into him, finally pounding him furiously, feeling the strap on bounce against his rubbery ass with an obscene slurping sound as she drove it home time after time.
"Do you like that? Do you like getting fucked up the ass?" she yelled as the lust filled her ears.
"Umm." Mark groaned into the bed, gasping for breath as the cock slid in and out of his tight asshole. "I love to get fucked," he mumbled.
