"No, Harry, I won't… and you can just turn right back around and get the hell out of here!"
Good for you, Susan! Lynn sighed inwardly as she heard her er sister tell Harry to get out. The last thing Lynn needed was Harry!
But Harry had other ideas.
Susan cried out loudly as Harry grabbed her wrist and twisted hard, yanking the key from her fingers. He threw the teen backward, slamming her into Julie.
"Hey!" Julie cried as Susan's elbow caught her right in her tit.
"Now, you girls just shut up! And sit down! I'll get to you later… right now I have something I want to give good old Lynn, here."
Harry pushed the door shut and locked it. He turned back to Lynn and walked over to where she lay on her back, breathing hard, her legs stretched out straight, her arms over her belly.
Harry gave her ribs a light kick with the toe of his shoe.
Lynn moaned and jerked away as he pressed the shoe harder into her side.
"Hello, Lynn. Remember your promise… last weekend?"
Lynn sighed and nodded. There was no use fighting it now, and no way she could if she wanted to, still bound like this.
"Good. Because I'm holding you to it… now! And if you give me a hard time of it… well… just keep in mind that your sister is right here… and she has a very pretty littie girl friend with her, too. Susan will take your place if you fuck up… understand?"
Lynn nodded again.
"Roll over, Rover!" Harry laughed, nudging Lynn's ribs with his toe again.
Lynn struggled to roll over onto her belly.
"Lift your ass up, bitch!"
Lynn crawled up into a dog-fucking pose, her ass high in the air, and she lowered her head to the rug.
Damn you, Harry! Lynn shouted at him in her mind. At least let the girls leave, so they don't have to watch you fuck my asshole!
"Now you girls watch real close… and you might learn something."
Harry laughed loudly. He unzipped the front of his pants and yanked his prick out, letting it wave merrily in front of the two girls, who simply stared back. Harry would have come right then and there if he'd even suspected what Julie and Susan had already been through today.
Harry got down onto his knees behind Lynn and pulled the rear hem of her white uniform up over her tight asscheeks, exposing her tight panties, pulled taut across the crack of her ass.
Harry stroked and petted Lynn's butt for several minutes before he slowly worked the waistband down over the firm hard globes of her stark white cheeks, pushed the material down to her knees.
He gulped at the vision before him – Lynn's ass, so white and unblemished, smooth like silk, tight.
And the sexy straps from the garterbelt riding up either side of her butt, framing her ass between the garterbelt, the straps, and the tops of her stockings – baring her perfectly!
He reached down and spread those sweet smooth cheeks open, kneading them in his palms as he looked at her puckered asshole – tiny and brown and buried deep between her butt-muscles.
"Beautiful! Either of you girls want to take a look at the most perfect asshole in the world?" He grinned over at them.
He had expected the two girls to make awful faces and shake theirs heads wildly – disgusted with his suggestion – but instead, they looked at each other for a moment, then shrugged and hopped off the couch. They came quickly over beside Harry and bent forward to take a look!
"Nice!" Julie said.
"Wow! Lynn, you've got a pretty rear end!" Susan said with a whistle.
Lynn cringed under this unexpected inspection – by her own sister! How could Susan stand there, looking at her shitter, knowing that in a minute Harry was going to shove his cock into her?
But there was nothing at all she could do about it.
"You girls want to touch this ass?"
Julie nodded and reached out, lightly stroking one firm cheek. She raised her eyebrows and smiled.
"So smooth," she whispered to Susan.
Susan hesitated, but finally she, too, reached out to her sister's ass and touched, with the tip of one finger, the brown pucker of her hole.
Lynn jerked and tried to squeeze her cheeks together, but Harry held them wide apart, astonished at the way these two pretty girls were playing with the bound woman.
Susan was licking her lips, frowning a little as she got an idea. Then she began twisting her pointed finger, working it through the tight ring of muscle guarding Lynn's bumhole.
Lynn groaned.
And Harry groaned, too, as Julie reached down while he wasn't looking and grasped his cock. She wrapped her hot hand around the thick prick and gave it a nice tight squeeze.
Harry gasped and grabbed the girl's wrist, afraid she was going to pull some kind of evil trick – hurt him – but he slowly relaxed his grip as he felt her lightly fingering his nuts, curling his hair around her fingertip, stroking the underside of his prick with her sharp fingernails.
"Let me suck it," Julie said, suddenly inspired by the image of Susan on her knees in front of Dr. Johnson, sucking his cock for him as he stroked her beautiful hair. She wanted to know what it was like, what a man's fuck-juices tasted like.
"You… want to suck my cock?"
Harry couldn't believe his luck!
"Yes, sir," Julie said, licking her lips sexily for him.
Harry let her draw him onto the rug, felt her get herself into position, scooting her knees up between his thighs as she got comfortable. She bent over and opened her mouth wide, and without hesitating at all, dove her throat down the pole of cock.
Susan took the opportunity to dim her finger all the way up Lynn's shithole. She began wiggling it all around inside her sister's hot tight ass.
Lynn began squirming all over the place, trying to pull her hole off the invading finger. But she began to feel so nice and warm, so horny again, after her long session of pain, that she let it happen – even though she knew it was her own sister who was doing it to her.
Susan was astounded at the tightness of her sister's shiner. She had never done such a thing to herself, and never even thought of doing it until Harry offered to show the girls this wonderful thing. And then, it all seemed so natural.
Susan bent her head down and pressed her wet lips to the incredibly smooth silken skin of Lynn's asscheek, licking the sweaty meat, purring, beginning to drool over the smooth globe. She felt Lynn twitch and move under her lips.
Lynn, her hands finally free, wiggled her ass backward against Susan's mouth, urging the girl to replace her finger with her tongue. Susan quickly got the idea. She pulled her finger from Lynn's hole with a loud sucking pop and clutched her sister's asscheeks, spread them wide, and dipped her pursed lips between the full firm globes, thrusting her hot wet tongue out as far as she could, curling it slightly, poking the tip against Lynn's asshole.
Lynn cried out into her gag.
Harry was crying out, too, biting his forearm to muffle the sounds of his panting pleasure.
Julie was bobbing her head wildly on his prick, slobbering all over it, drooling into his cockhair.
She was one of the best Harry had ever had suck his cock!
Her lips sucked and kissed all around the cylinder of his throbbing prick, making him arch his hips off the floor and jerk his cockhead against the back of Julie's gulping gagging throat, forcing little cries of pain and delight from the girl.
Julie loved sucking cock. She loved it more than getting raped, being tied to a table and fucked. She knew from the first touch of her tongue to Harry's prick that she was a born cocksucker.
She dove her head between his thighs and licked at his pants while her fingers fumbled open the front of his tight jeans, yanked them awkwardly down his legs and off his feet, then went back for his underpants, working his fat long cock back inside them before ripping them in a lusty frenzy down his legs and throwing them over her shoulder.
