Sibling Rivalry : Mommy’s Threesomes 61

Doris Heaney’s two children were competitive, even into adulthood.  Sally and George always tried to best each other, so when Sally catches George giving their mother a glorious climax, she’s determined to match him.  Taken aback at her casual approach to their incest, Doris agrees and soon she’s repaying her son and daughter with orgasms of their own!

Read An Excerpt

Doris was beside herself.  The shame of being discovered with her son between her legs had only just arrived, and now she was wrestling with the idea of allowing her daughter between there too.  But Doris was curious, that was for sure, and if one orgasm felt good, well then two … that would be incredible.

George watched dumbfounded as his mom let her legs be opened and Sally stared along her thighs and into her soaked crease.

“Damn, he did a number on you,” Sally said, and she could see her mother’s cum at the inside of her thigh and all around her pussy.

“He was quite good,” Doris said, and she didn’t realize that the comment was like peanut butter to a pooch.

“We’ll see about that,” said Sally, and she pressed her face right into her mother’s pussy without hesitation.

George sat up, immediately curious.  He instantly looked upon his sister differently.  Far from being a rival, now she was a colleague in sin, performing her first lesbian act on their own mother.  If George’s cock wasn’t hard enough already, suddenly it had turned into granite.

He squeezed at his cock while his sister, clad in her pristine basketball jersey, went to town on their mother.

Doris was at first tense, but soon she relaxed into Sally’s rhythm, noting that her touch was much more sensual than George’s.

Sally tasted her mother’s cum.  It was sweet and salty on her tongue all at once and much more pleasurable that she’d ever imagined it to be.

She closed her eyes and pressed her lips into the soft mound of her mother, finding her hard clit and targeting that just like George had.

George noted the curve of his sister’s back and how the basketball shorts pulled tight around her ass as she knelt on her hands and knees.  He saw her sports bra beneath her loose jersey and started to picture his sister without any clothes on at all.  It felt strange to him to think of her like that, but there were much stranger things occurring.  George let his imagination run, and soon his imagination wasn’t enough.

He got on his knees behind his sister and looked down at the bulge at the front of his sweatpants.  He pressed it between her ass, causing Sally to pull her face off her mom’s pussy and turn to look back.

Doris’s eyes opened and she watched the exchange with keen interest.

“What are you doing?” asked Sally.

“I just wanted to see what it looked like,” George said, looking down.  “I just wanted to imagine it.”

Sally seemed to think.  “Why not just do it for real?” she said, looking back at her mom.

Doris didn’t say anything.  She’d let them figure this out themselves.

“You mean …” began George.

“Put it in,” said Sally, looking back at George again.  “I always thought you had a big one.  I want to see if that’s true.”

She looked back to her mom and then put her mouth right back over her pussy, waiting for George to make his move behind her.

George was dumbstruck and catatonic.  He looked down on his sister’s ass in disbelief.  Now that he’d been granted access, he was having trouble acting on it.

“Go on,” urged Doris, sensing her son’s trepidation.  “Pull it down and look, at least.  You might like what you see.”
