Mother May I update

Cass lifted her dress to her waist, watching her ‘mother’ to see if she would stop her. But Selina didn’t move except to crane her head for a better look. Her green eyes seemed to sparkle as she took in Cass’s panties, pale blue with white lace. When Cass turned around, smiling to herself, the panties ran between the cheeks of her succulent young ass, showing off almost all of it.

“That looks uncomfortable,” Selina mewled to Tim. “Maybe you should take them off her.”

Tim looked at his adopted mother. Despite her sultry words, she was ignoring him to stare at the sweetness of Cass’s small, svelte ass. He couldn’t believe this, but after an entire day of Selina teasing him and goading him with her tantalizing voice, her perfect body, and her overt sexuality—clearly Cass had seen how hot he’d gotten and now she was taking steps to attend to him, as directly as she did everything else.

“Go on, Tim,” Selina taunted him. “No one’s going to mistake her for really being your sister. Maybe a transfer student from the kind of Japanese school where they all dress in sailor outfits…”

Tim set his jaw. He’d show her. He knelt on the floor behind Cass. He couldn’t bring himself to remove Cass’s panties, but he didn’t have to. As she giggled with delicious wickedness, she parted the cheeks of her ass with her small hands. Then Cass looked behind herself at Tim.

“Do to me… what you wanted to do to her…”

Selina squeezed her thighs together tightly, watching as Tim kissed Cass’s small ass. She saw his tongue come out and slide over the toned flesh that made up all of Cass’s trim, slender body. Cass gasped a little and wiggled her ass in his face. Tim moaned with pleasure himself, planting one hand on Cass’s firm buttock and with the other, rubbing at the bulge in his pants. 

Selina dropped down beside them, wrestling Tim’s prick out into the open, then pumping it as she watched Tim tickle his tongue into the valley of Cass’s quivering ass. 

“Does it taste good, Tim?” she whispered. “Does Cass’s tight little ass taste as sweet as she is?”

“If it doesn’t…” Cass interrupted, her sporadic speech even slower as it was broken up by Tim’s tongue going between her thighs, sliding along the crotch of her panties, then rolling over the curve of her buttocks again.. “I’d like to see him… with an ass… that does taste good!”

“Mmmm… so would I!” Selina smirked, hooking a finger into Cass’s panties and pulling them to one side, showing off the tight pucker of Cass’s pink asshole. “Go on, Tim. If you want to fuck it, first you have to lick it. Even if she is family.”

Resolutely ignoring Selina, Tim nevertheless tongued Cass’s asshole.

Cass whimpered softly, her tight ass jutting back into Tim’s face. Her hands tightened on her asscheeks, holding them apart, and her eyes glazed over with warming pleasure. She was still aware of Selina holding Tim’s manhood in her hand. Cass forced herself to look at it, enjoying the sight as well as the wet heat of Tim’s tongue inside her anus. The combination brought a low cry out of her, while her pussy tensed in ways she never could’ve imagined.

“Ooooh… yes!” she sighed, pressing her silken ass into Tim’s face.

Selina crouched beside the two of them, one hand squeezing Tim’s cock, the other holding Cass’s panties out of the way so Tim could eat her ass. Her breasts heaved with excitement as she watched Tim lick up and down on Cass’s asshole. She didn’t resent Tim for choosing a younger model over her. Now that he’d given in and started fucking, she doubted she would be left out.

“You’re… turned on… like he is!” Cass gasped,

“Uh-huh,” Selina nodded, gripping Tim’s manhood tightly. “I like watching you with a tongue in your pretty ass. You look like you’re having fun.”

“I am!”

Tim lapped wetly at Cass’s anus, swirling his tongue around its wrinkled rim. Until finally, he couldn’t take it anymore. He grabbed hold of her panties and ripped them in half, now able to shove his face between Cass’s buttocks and kiss her asshole with all his tongue.

With her hand free, Selina ran it down her body, cupping her pussy, squeezing, then fucking two fingers into her juicy slit.

“You!” Cass panted as she watched. “Are doing… wet things… making wet sounds…”

“So are you,” Selina purred, opening her legs, letting her dress ride up so that her pussy was exposed. She stroked herself at the same time that she rubbed her thumb into Tim’s pulsing shaft. He still hadn’t done anything about her fondling him. “I guess Tim does like your taste. I wonder if he’d be willing to share…”

Cass wiggled her ass in pleasure, as much at Selina’s words as Tim’s licking. Both her male and female lovers could see the sparsely-haired slit of Cass’s sex, her lovely ass and the little pink hole between her splayed buttocks. Tim’s prick throbbed with need inside Selina’s fist, his balls so full they seemed desperate to drain themselves. 

Selina gasped softly as she curled and twisted her finger inside herself. With glazed eyes, Cass looked at Selina’s pleasure, then turned her eyes to Tim’s cock as it bulged from Selina’s squeezing hand. She bent over as if to touch her toes, reaching between her legs to touch Tim’s open fly and pull out his balls. She squeezed them as Selina squeezed his member.

Tim could only circle his tongue around Cass’s hole, then drop his mouth between her thighs, whipping his tongue at her exquisitely tight sex and the tender folds inside.

“Tim! Give! Give, Tim!” Cass cried out, desperate but unable to say more than that Tim should give her what she needed.

Selina knew what she wanted. “Lick her pretty little cunt,” she mewled. “Eat your sister’s pussy.”

Bringing his arms around Cass’s slender thighs, Tim pulled her open to make room for his head and then worked his mouth against her soft pussy. His tongue he pressed into the boiling tightness of her pussy.

“Tim!” Cass cried out again, the heat of his tongue and what it was doing to her pussy feeling like it was branding her.

Selina desperately fingered herself, kissing Cass’s smooth thigh as she fucked her cunt on her hand. The muscles of Cass’s legs tensed and corded; Selina ran her moist lips over them, her tongue licking over Tim’s arm where he held Cass tightly. Then she lapped it over Cass’s slim ass, licking down the slope of her buttock until she was cheek to cheek with Tim. 

She took her hand away from her pussy with some regret and ran it along the curve of the bent-over Cassandra, feeling her out with her fingers as she’d done with her tongue, until she found the top of Cass’s slit as Tim had found the bottom. There, she slicked her fingertips against Cass’s clit, twirling the pads of her fingers around it, rubbing firmly at its hood while Tim licked the rest of Cass’s needing sex.

Cass was almost out of her mind with desire as she gripped Tim’s balls. She needed more. She shoved her other hand between Selina’s thighs and rubbed at her adopted mother’s pussy. While the two felt her up, fondled her, fed on her, she pumped Tim’s balls and massaged Selina’s cunt. 

Selina kissed Cass’s buttock, then Tim’s cheek, leaving her dark lipstick on both before she fell back on her elbows and pushed her sex into Cass’s hand. Cass released a tight, moaning squeal at Selina’s absence, but Tim soon made up for that, drawing his tongue from her slit down to her asshole and back again.

“Look at us!” Selina moaned. “We’re really bonding!”
