Mona stayed the night. Around midnight the two of them finally fell asleep in each other's arms. Neither she nor Erica could have counted the number of times each had, came Mona had not known it was possible to come so much.
She had never gone through such a tireless marathon of fucking with a man as she went through with Erica. After the first time, they had returned to the living room for another martini.
The music and the gin and the hot forbidden fucking that was in store made Mona feel ecstatic. She got up and started dancing in front of Erica. She swayed before Erica's fascinated gaze.
"You like?" she teased.
"I like," Erica replied in a husky sensual voice. She ran her hands over her body, moaning softly.
Half-hypnotized, Erica got up and began to dance too. She caressed her own body as she danced. They teased one another as their bare excited bodies drew close, then slipped tantalizingly away.
Mona slid two fingers into her wet curd, masturbating slowly as she danced. Erica did the same.
Mona reached out for Erica.
Moaning and panting, they slumped to the rug in the center of the living room floor.
"I want to fuck with you. I'll just never get enough of you, never!" Mona murmured, sliding her lips down Erica's supple body, devouring her sister-in-law's dark nipples.
Erica arched her back, thrusting her tits at Mona's sucking mouth. "Sixty-nine, baby, sixty-nine," she panted. "Both at once, both at once!"
Within seconds they squirmed into position. Erica was flat on her back with Mona crouching over her. Mona pushed her throbbing breasts into the girl's smooth heaving belly, then dipped her tongue into Erica's cunt.
She felt Erica's arms and hands encircling her hips, clasping her ass, drawing her pussy down. Then the girl's hot slithery tongue slid into her own achy slit.
Erica's hungry lips plucked at Mona's swollen clit. Mona writhed and dug her fingers into Erica's clenching asscheeks and buried her mouth in the girl's sopping wet quim. Again, the coming took them quickly by surprise. They groaned and thrashed with bliss, their hot shuddering bodies welded together.
After that they tried to fix something to eat.
"We have to keep up our strength," Mona joked.
Erica took a couple of TV dinners out of the refrigerator and grimaced at them. "Do we really have to?"
Mona smiled. "You think we can keep this up forever?"
Erica blushed. "Yes."
"Oh baby?"
They were suddenly all over each other again, right there in the kitchen. They stroked and sucked and finger-fucked one another insatiably. The TV dinners were ignored as the two naked girls wriggled together on the cold kitchen floor.
But the hard chilly vinyl tile was too much for them.
"Let's take a bath together," Mona said.
"Good idea. This floor is killing me."
In the warm bath Mona lathered Erica's voluptuous body. Erica shut her eyes and smiled with contented pleasure as Mona's hands massaged her soap-slick breasts.
"Have you ever come just from having your titties sucked?" Erica asked dreamily.
"No," Mona whispered.
"I never felt like it either until you were doing it to me a little while ago."
Aroused by Erica's words, Mona began to work on the girl's succulent nipples with her fingers.
"Where? In the kitchen?"
Erica sighed and sniffed, as her nipples grew thick and erect in Mona's fingers.
"In the living room? In the bedroom?"
"Everywhere," Erica breathed.
Mona cupped her hands and spilled warm water on Erica's tits, washing off the soap. Erica's shiny wet body made Mona pant with desire. She kissed Erica's nipples and began sucking softly on one, then the other. "Like this?" she whispered.
"Yessssss! Oh, it feels so good!"
"They're so sensitive." Mona began to suck harder.
"I know. But I never felt this way when a man did it."
Erica's body churned and squirmed in the bathtub. She panted and gasped, clutching the side of the tub with one hand.
"Ohhh! I wish you could suck them both at once," she moaned.
Mona opened her mouth as wide as she could and sucked Erica's tit. She sucked as hard as she could.
"Uunnhhhh!" Erica grunted deliriously. She thrashed so wildly that water sloshed out of the tub onto the floor.
Mona, wondering if Erica really could come this way, turned up the heat. She mauled the girl's nipples brutally with her lips and fingers and teeth.
"Ohh!" Erica whimpered. "I am! Oh baby… now! Aannnnggghhhhh!"
More water splashed out on the floor as Erica writhed and moaned through her climax.
"Oh God, baby," she said to Mona as they climbed out of the tub finally and began mopping up the spilled water with towels. "I never knew something like that was possible!"
"Was it good?"
"Jesus. It felt like my titties were exploding."
"I was afraid I might be hurting you."
Erica smiled, toweling off Mona's ass. "It did. It hurt beautifully."
"You'll have to try it on me sometime," Mona said.
Erica stooped and pried apart Mona's moist glowing ass-cheeks. Suddenly she ran her skillful tongue up and down the crack of Mona's ass until Mona was shivering and whimpering.
At the same time Erica thrust two quick fingers into Mona's cunt from the rear. She kept licking her ass-crack, and reaching up with one hand to tweak and scissor Mona's damp excited nipples, while her fingers plunged rapidly up and down in Mona's boiling pussy.
Mona's knees grew so weak that she had to grab a towel-rack to keep from falling. "Oh! Ohhhh!" she gasped.
But she spread her feet and thighs and pressed her cheek against the tiled wall. She gyrated her hips. And within seconds she came standing up, gagging joyously on the sweet sharp sensations that gripped her trembling body.
After the bath, they went back into the bedroom and lay down on the bed. They began a long slow session of fucking and sucking that lasted until well after midnight.
Just when it seemed to Mona that neither of them would ever be able to come again, she would feel Erica's body clench, and feel the hot tremors roll through her as she climaxed. She herself would be surprised by other orgasms ass he lay on her back in a warm smoky haze, feeling Erica's lips curling into the wet tingly folds of her cunt.
In the morning it was the same thing all over again. They each climaxed twice before even getting out of the bed.
"My God, we've got to stop this," Mona sighed. Her body felt deliciously raw and achy. But she knew that if she didn't have to go to work she would stay in Erica's arms all day, lesbian-fucking until her brains melted and she went blind from repeated coming.
"I know, I know," Erica sighed. "I never knew anything like this was possible. I've never felt this way with a man."
Mona got up to dress while Erica made her a cup of coffee.
"I can't believe it," Mona said. "I still want you… I still do!"
"You could… call in sick," Erica said tentatively.
Mona shook her head. "We can't let it get control of us like this."
"No. I guess you're right." Erica went over to her and kissed her mouth. "But you have to promise me something." She slid one hand beneath Mona's skirt, pressing it against the gauzy fabric of Mona's panties, already wet again with pussy-juice.
"Ohhh!" Mona sighed. "What do you want me to promise?"
"We have to do it again. I mean, at first I was scared to death. But now I don't think I could stand it if I never got to fuck with you again."
"I know. I feel that way too. But what about Steve?"
"Screw Steve!" Erica panted into her ear. "Just let me fuck you and fuck you forever. I'll never think about Steve or any other man again."
Erica's single-mindedness made Mona uneasy. It sounded so damned… lesbian.
"I have to go," Mona said. "Oh baby, I have to go. But I'll call you, we'll do it again. Soon. I promise."
