The throbbing stiffness of his cock was evidence enough of his own excitement at what he'd done. He climbed on Marilyn's slender back, his hands spreading her quaking thighs apart.
"Now stick your big dick up my asshole! Ram it up my ass!"
Lining the pulsing head of his prick up with Marilyn's puckered asshole, he held himself up with his hands on her lower back. He gritted his teeth and slammed his hips forward, his thick cock jamming halfway into her slick rectum. Again he pushed forward, this time his long prick disappearing the rest of the way into Marilyn's throbbing asshole.
"I can probably come like this if you screw my ass hard enough!" She gasped when Derek started sliding his prick in and out. "Oh, it feels delicious! Ream my asshole out until it's raw! Ohhhhhh! Fuck my butt harder! Harder and faster!"
Pressing his broad chest into Marilyn's back, Derek held her naked hips down with both hands while he pounded his twitching cock up her ass.
Marilyn could feel his hot breath on the back of her neck, every thrust of his long prick sending shivers tracing down her spine. She worked her hips with a jerky, pumping motion, pushing her firm ass back into his crotch each time he thrust forward.
"When you pump your ass like that, your asshole grabs at my cock!" He shuddered, his fingers digging into the soft flesh of her churning hips. "Even the cheeks of your ass grab at me when they close up!"
Still clutching at the edge of the mattress, Marilyn groaned non-stop and squirmed around. She kept tightening the still-stinging cheeks of her ass together, her action making the slick passageway of her asshole clench around Derek's pistoning cock. Her tight rectum sucked noisily at his prick, gripping it tighter and tighter.
With her firm tits pressed flat to the bed, she could feel her swollen nipples throbbing.
"I'm so close to coming I can taste it!" Marilyn sobbed with the lewd pleasure racing through her entire body. "Uhhh! Uhhhh! Fuck my asshole good and hard! I'm going to come any second now!"
Her skin shone with sweat, her supple body jerking and writhing. She pumped her naked ass with a passion, her hot asshole encasing and sucking at the hard cock within it.
Derek slid his hands down from where he gripped her squirming hips. With the fingers of both hands, he dug into the juicy crack of her cunt, his fingertips sliding up into her cunt-hole eagerly. He squeezed her hairy pussy until her oily juices dripped between his fingers.
Gasping for breath, Marilyn started coming. Her slick asshole contracted tightly around Derek's cock, squeezing it wetly until his cum began shooting up her wriggling ass.
"Squirt all your cum up my butt!" the girl moaned homely, feeling the sticky liquid pour into her trembling bowels. She tensed until she was shaking violently. "I'm coming, too! Keep fucking with my pussy! Squeeze it! Squeeze the hell out of my pussy! Uhhh! Ohhh! God!"
Derek pumped his pearly cum into Marilyn's wetly-gripping asshole with cock-thrust after ramming cock-thrust.
"Hump my little ass off!" Marilyn kept groaning. "Hump my ass till it hurts! Ohhhhhh! It's so good! Fill my asshole with cum! Ohhhhh! Damn, it feels so good!"
CHAPTER SEVEN
Two evening later, Marilyn was once again showing a prospective buyer through the vacant Sutton mansion.
Her client this time was Andrea McAllister, a strikingly pretty young woman of about twenty who had inherited a fortune from her father. With sleek black hair, finely chiseled features, and huge blue eyes, Andrea wore tight ragged jeans and a skimpy halter top that seemed barely capable of restraining her delightfully jiggling tits. She carried a denim bag slung casually over one shoulder.
"This place could be beautiful with the right furniture," the young heiress commented as the two walked down the long upstairs hallway. Andrea poked her head into a carpeted and draped room, flipped the light on and then off, then moved to the next one. "It's really quite impressive."
In contrast to the almost sloppy way she was dressed, Andrea had driven up to the house in a low sports car that Marilyn would have guessed cost even more than George Rankin's limousine. Such were the privileges of the very wealthy, Marilyn couldn't help thinking to herself, actually feeling somewhat overdressed in her pleated skirt and frilly blouse.
"There're eight bedrooms in all," Marilyn volunteered helpfully, following the girl. "And twelve bathrooms."
The bathroom at the end of the hall was right before them, and Andrea said, "Speaking of bathrooms, I could use one right now."
Leaving the door open, the shapely young woman stepped into the large bathroom and quickly pushed down her tight jeans. Unconcerned that Marilyn stood before her, Andrea sat on the toilet and kept right on talking while she pissed.
"It's a lovely house," the girl perched on the toilet seat her jeans down around her slim legs. Marilyn had not been particularly surprised to discover that Andrea was not wearing underwear. "I might just buy it."
Looking away uncomfortably, Marilyn said, "The Suttons want to sell it in a hurry so the price is very reasonable."
"Damn!" she heard Andrea curse. "I'm sitting here with a dripping pussy, and there's no toilet paper. I hope I have some tissues."
Marilyn turned to see the slender-hipped girl rummaging through her denim bag. Andrea's bare legs were tanned and smooth, her firm ass as round as could be, and from where Marilyn stood she could glimpse just a hint of the curly cunt-hair that covered Andrea snatch.
Slightly aroused at the sight in spite of herself, Marilyn let her eyes take in the half-naked girl without being overly obvious about it. The thought of her last encounter with another girl – Gail Sutton – made Marilyn's breath quicken almost imperceptibly.
"I guess I'll just have to drip dry," Andrea sighed finally, unable to find any tissue.
And when she set her denim bag on the tiled floor, it tipped over, spilling its contents. Keys, makeup, hairpins, math books and other small items poured out in a jumble.
Most intriguing to Marilyn, however, was a huge cordless vibrator in the shape of a man's stiff cock. At least twelve inches long, it was made of smoothly polished plastic and – to Marilyn's amazement – had tiny, delicate daisies painted all over it.
"That's my pacifier." Andrea giggled when she noticed Marilyn staring at the vibrator. "I get a better tinge out of it than any man's cock could give me."
"Really?" Marilyn asked with genuine curiosity. "I've never even seen one – except in some of my husband's girly magazines."
Picking up the huge plastic cock, Andrea flipped it on and held it out for Marilyn to see. The vibrator hummed in her hand.
"You can look at it if you want," she offered, handing it to Marilyn.
While Andrea scooped everything back into her denim purse, Marilyn examined the faintly buzzing plastic prick. As big around as it was, she could only imagine that it would stretch her tight cunt to the bursting point if she ever tried to use it on herself.
"It really vibrates!" Marilyn said in almost a whisper. "It's getting me horny just holding it in my hand."
Giggling, Andrea told her, "It'll make your clit stand right up! Here, let me see it and I'll show you how it works."
"Okay." Marilyn nodded eagerly, giving the humming vibrator back to the girl.
Squatting in front of the toilet, Marilyn watched with ever-quickening breath as Andrea kicked her shoes and jeans away and scooted her bare ass forward on the toilet seat. The pretty heiress stretched her long legs out in front of herself and spread her knees wide, the lush slash of her pink cunt gaping lewdly when she did so.
Marilyn found herself staring up into Andrea's glistening pussy, her eyes widening at the lust-inspiring sight.
The dark-haired girl's swollen cunt-lips were so large they protruded wetly, their pink surfaces slick with oily wetness and trembling faintly.
