Denise was determined to break up Paul's marriage. She hated her sister-in-law more than ever. She thought about it by the hour and then made a decision.
She waited for a day she and Marilyn would be home alone. She pretended to have a problem and asked Marilyn to listen for a while. Marilyn seemed pleased by the approach. "Have some coffee, Sis," she said to the blonde in the kitchen.
Denise bristled at the term, but smiled. "Let's go into the living room," she said. "It's more comfortable in there. I always did love that room."
Marilyn smiled to herself. It was obvious what Denise meant. Denise had picked out this house and every piece of furniture in it. The living room sofa had been her choice and Marilyn hated it. She decided long ago that the moment Denise moved out she would buy a new one.
Denise padded into the living room, wearing only a sheer, pink, short nightgown. Marilyn followed her, thinking it was strange that the blonde was almost naked. She didn't even have slippers on.
Denise sat down in the middle of the sofa, placing her coffee cup on the table in front of her. "It's nice of you to take the time to talk to me," she said, her eyes down on the floor and her checks flushing. "But I just know you'll know what to do. Paul says you're very wise."
Marilyn stared at Denise. The blonde tucked her legs up under her. Why is she flattering me like that? Marilyn thought. Something's up. I'll just stay cool and find out.
"I don't know how wise I am," she said out loud, "but I'll do my best."
"That's all anyone can do," Denise said, a strange glint in her eyes.
Marilyn sat down at the end of the sofa and pulled the belt of her robe tighter. There was something eerie about Denise. She didn't know what it was, but something was wrong.
Suddenly Denise giggled. "Don't be afraid to sit closer to me," she said, patting the cushion. "We're sisters, aren't we? Come here and let's get nice and cozy."
Marilyn stared at her. Denise's eyes darkened and Marilyn's heart pounded. There was something strange going, on and she was almost afraid to find out what.
She shifted around on the seat and moved closer to the blonde. "What did you want to talk to me about?" she said.
"Talk to you about?" Denise had a blank expression on her face.
"Yes, you said you had a problem," Marilyn said.
"A problem?" Denise stared across the room, her eyes unblinking.
Marilyn wondered if the older woman was having a fit of some kind. Paul had never mentioned that his sister had a neurological problem. Still, anything was possible.
A few minutes passed. Denise stared into space and Marilyn said nothing. She decided to wait for the blonde to start talking. If she was haying a fit of some kind, Marilyn didn't want to get involved in it.
Another five minutes passed. "Are you okay?" Marilyn said. She was beginning to feel nervous.
Denise finally blinked. She smiled. "I'm fine. Just fine."
She sat back on the sofa and hummed while Marilyn fidgeted. "Well, I guess I'll go upstairs and dress," she said, rising up.
Denise sprang up too. "I'll go with you." She ran in front of her sister-in-law. "Don't you just love this living room?" Denise said, her voice shrill and hysterical.
"Yes, it's nice," Marilyn said. She couldn't be totally hypocritical, but what could she say? She couldn't tell Denise it was the ugliest room she'd ever seen.
"Paul just loves my taste," Denise said as they walked upstairs. "Oh, but he's just used it." Her eyes narrowed. "Same day he'll like your taste too."
Marilyn went into the bathroom and ran the water in the tub. Denise came into the room after a moment and rummaged around the vanity. "I used to keep some lotion in here," she said.
Now Marilyn knew her sister-in-law was just killing time. She had something planned, and it wasn't something that would reflect well on Marilyn.
But the younger woman knew how to take care of herself. All the years she'd spent taking care of her parents had taught her something. She sat down on the toilet seat and waited for Denise to leave before she dropped her robe to get into the tub.
"Well, I'll leave you alone now," Denise finally said. Her eyes flickered over Marilyn's body. "Don't tell me you're modest?" she sneered.
"Not really," Marilyn said, pulling her belt tighter around her waist.
"Well, I'll leave you alone now," Denise repeated.
As soon as Denise was gone, Marilyn slipped her robe off and stepped into the tub. She poured some bath oil into the water and turned the hot water on all the way.
She lay back and let the hot oily water slosh aver her. Denise was acting very peculiar. More peculiar than usual. And Marilyn couldn't figure out why.
She soaped up her tits and the swamp between her legs and thought about her sister-in-law. She knew Denise hated her. The woman was plotting something. What could it be?
She used a washcloth to rub her crotch. It felt good and with a tiny sigh she began masturbating. She fingered her pussy and stopped thinking about Denise. Then suddenly the door opened and the blonde walked in.
"Sorry to bother you, dear," Denise said, plopping down on the toilet seat.
"Oh, that's okay," Marilyn said, taking her hand away from her cunt. She wondered if Denise had seen what she was doing. "I'm spending too much time in here anyway."
"So I see," Denise said. "But then you were having such a good time, weren't you?"
They stared into each other's eyes. Denise glared wickedly and Marilyn smiled. "I wasn't even aware of what I was doing," she said.
"Fat chance," Denise smirked. Her eyes bore into Marilyn's tits. "You certainly have big breasts, don't you?"
"Yes, I do," Marilyn said.
"Paul never liked big breasts," Denise said, her voice suddenly warm and sweet. She glanced down at her own chest. She was still wearing the sheer pink nightgown and her tits jutted out.
"The Green women all have nice firm boobies," she said. "Paul was raised on them. I can't imagine what he saw in yours. They're so big. They'll be down to your knees by the time you're forty."
"Yours are almost as big as mine," Marilyn said. She was beginning to get angry.
"But they don't hang," Denise said triumphantly.
Marilyn didn't answer. She knew Denise was jealous. "I think I'd better finish up in here," she said.
Denise leaned forward and her hands almost touched the tub. "I guess you want me to get out of here."
Marilyn stared at her sister-in-law's tits. She could see through the sheerness of her night gown that her nipples were taut and big. She felt a rush in her cunt and picked up the soap.
"I don't care!" Marilyn said. What were those strange sensations in her crotch?
Now Denise sank dawn to the floor next to the tub. She let one hand drop into the hot water and she closely scrutinized Marilyn's body. "You're quite curvy, aren't you?"
Marilyn giggled. "Yes, I'm guilty of that too."
"What do you mean by that?" Her hand touched Marilyn's thigh.
"I mean I'm guilty of that too."
Denise moved her hand up and splashed some water over Marilyn's tits. "It's not a matter of being guilty," she said. She cupped Marilyn's right tit under the water. "Do you have a lot of feeling in your boobs?"
Marilyn held her breath and leaned her head back against the tub. "Yes. Do you?"
"What a question!" Denise said shrilly.
Denise's gown slipped up and Marilyn sighed when the alder women reached over and massaged the back of her neck. It felt good and the brunette closed her eyes and let her head fall forward.
"I'll give you a body massage, if you want," Denise hissed. She caressed the small of Marilyn's back and her shoulder blades. "Get out of there. I'm very good at giving massages."
Without a word, and in a trance-like state, Marilyn rose up and stepped out of the tub.
She let the older woman wrap her in a towel.
Denise dried her off, murmuring about what a lovely massage she would give her.
The naked woman blushed. She suddenly realized what was happening. She took the towel from Denise and covered her nakedness. "I think you better go," she said.
Denise took Marilyn into her arms and hugged her. "Let's be friends," she trilled. "For Paul's sake." Suddenly Denise crouched down and slid her hand between Marilyn's legs. "You were playing with yourself before, weren't you? I know you were. I saw you."
"I think you better leave, Denise," Marilyn said weakly.
Marilyn found herself leaning against the wall while Denise rubbed the flat of her hand up and down her wide-open slit. A tingle of hot pleasure raged through her.
"Let's be friends for Paul's sake," Denise chanted. Her eyes sparkled wildly.
Marilyn felt weak with desire. Jolts of sensation shot through her hairy cunt. Denise's fingers toyed with the curly tendrils of hair and teased her cunt-folds.
"What are you doing?" Marilyn murmured. She held her breath and let the lovely sensations engulf her.
"I'm doing it for you," she said.
The blanket fell to the floor and Marilyn's tits heaved as her sister-in-law frigged her. "Why are you doing this to me?" Marilyn sighed. She humped her ass and thrust herself at Denise's fingers.
"I just want you to feel good," Denise snickered nastily.
A shudder of erotic pleasure coursed through Marilyn's body. "You won't tell Paul, will you?"
"Of course not!" Denise said. "What do you think I am?"
"Oh, God, you're going to make me come!" Marilyn gasped.
"You slut! Let's go into the bedroom," Denise snapped. She stopped fingering Marilyn's cunt and the two women walked down the hall to Denise's bedroom.
Marilyn climbed onto the bed and Denise whipped her nightgown off and joined her.
"Lay down and spread your legs," the blonde hissed. Her eyes were wild and lust filled. Her lips glistened wetly. "Get in your usual position, slut!" she snarled.
"Promise, you won't tell Paul," Marilyn whispered. She had last control of herself and although she knew Denise wasn't her friend, she felt compelled to lay still and let her touch her all over.
Denise lowered her face to Marilyn's cunt. Marilyn tossed her head back and forth on the pillow as the blonde tongued her gash. "I'll bet you never had another woman lick your cunt before," Denise said. "Or have you tried everything?"
"No! No! Never!" Marilyn said.
The younger woman's thighs trembled uncontrollably and Denise pushed them farther apart and ran the tip of her tongue up and down her slit from her cunt to her asshole.
"I'm told that once a woman experiences another woman's tongue on her privates, she's never happy with a man again," Denise said.
"It certainly feels good," Marilyn said in a tiny voice.
"You are a slut, aren't you?" Denise said. She thrust a finger into her sister-in-law's cunthole and licked her cunt.
"Don't say that!" Marilyn sighed.
"Why shouldn't I speak the truth?" Denise said. "Someone around here has to be realistic."
It occurred to Marilyn then what Denise was doing. She was going to blackmail her with Paul. She would tell Paul Marilyn was a lesbian. The young wife was determined not to let her get away with it.
Denise pushed her onto her belly and Marilyn shoved her ass back at the blonde. She rested her cheek on her arms and felt Denise's hands knead and squeeze her ass. A low moan escaped her throat as the older woman's fingers stroked her throbbing flesh.
Denise pushed her onto her side and began stroking her quivering tits. She pinched her nipples until they were taut and then she climbed over her and sucked one of them into her mouth.
Marilyn wasted no time in thrusting her own hand between Denise's thighs. "No! Don't touch me!" Denise rasped.
"I must," Marilyn whispered. "I want to touch you too."
She knew the only way to foil Denise's plan was to touch her and lick her too. And strangely enough, it felt right. Denise stopped arguing when Marilyn found her clit and began rubbing it back and forth. The blonde sighed deeply and thrust her cunt against Marilyn's hand.
"Stick your finger in me!" she hissed.
"Like this?" Marilyn said.
"Yes! Stick it in and out!"
"How's this?" Marilyn snaked two more fingers into Denise's twat and used them like a cock.
"More! More!" Denise cried.
"I can't fit another one in," Marilyn said. "Shall I lick it for you."
Denise flopped over onto her back and lewdly spread her legs. "Yes! Lick it!"
Marilyn took a deep breath and crouched between Denise's wide-spread thighs. She sniffed delicately and then held her breath while she flicked her tongue over the older woman's gash.
"Aaaaaahhhhhh!" Denise cried.
Marilyn tongued vigorously and then she slid up Denise's body and planted her lips on the blonde's. The two women clung together, tit against tit and tongues dueling.
They rubbed their cunts together. Marilyn held onto Denise's ass and dipped her fingertips into her asscrack.
"Stick a finger into my asshole!" Denise breathed, and Marilyn moistened a fingertip with Denise's joy-juice and thrust it into her bung.
"Beautiful!" Denise shrieked. "Deeper!"
Marilyn stroked her finger more deeply into her sister-in-law's shitter. Denise clamped her lips over one of Marilyn's big tits and nursed it.
The two women bounced around the bed in orgiastic frenzy. Hot flames of desire raged through Marilyn and when she saw Denise's face she knew the blonde was thoroughly aroused too.
"Let me suck you again!" Denise said, and Marilyn lay back and let the older women flick her tongue back and forth from one cuntflap to the other.
Denise went down Marilyn's pussy thicket and tongued her inner thighs. "I'm going to give you a climax," Denise giggled.
"Yes! I'm ready!" Marilyn said.
Denise thrust her thumb into Marilyn's cunthole and licked her cunt. "You know, I used to hate you," she said.
"Don't stop!" Marilyn cried.
"I used to hate you, but I don't anymore," Denise said.
"Oh, God, so good!" Marilyn moaned helplessly.
"Come, you slut!" Denise snarled. "Come, you filthy, cock-hungry slut!"
"So good!" Marilyn sighed as her orgasm tapered off. "So damn good!"
"Oh, my God, what have I done?" Denise cried. "Dear God in heaven, what have I done?"
Marilyn sat up and giggled. Denise lay down on her back and Marilyn hovered over her. She extended a finger and run it from the blonde's cleavage to her cunt-mound.
"Ssshhh, Denise," she whispered. "I won't tell if you won't."
