Use Your Sisters Instead: EP8

After dinner, Mary got caught up in a show and stayed up far too late. She snuck upstairs, but saw a light escaping under the door to Michael's bedroom. Mary knocked - she hoped her son wasn't up late, troubled with something. She needn't have bothered. Instead, she found Michael laying back on the bed. Hope firmly planted on her brother's cock. Her body hung over him. He was holding her tiny breasts in his hands while she slowly rode up and down on his member. Chastity was sitting next to them on the bed, naked as well. Watching intently.

"Lord, don't you ever stop?" Mary asked, "It's two in the morning!"

"Shhhhh, Mom," Chastity said, "You'll wake Tabitha."

If their mother's presence bothered them, the siblings didn't let it show. Hope continued to ride her brother, moving almost sensuously - snake-like, Mary thought. Michael's head rested against the pillows, eyes slammed shut. "Michael couldn't sleep," Chastity said, "And my pussy. I mean my vagi..."

"It's fine," Mary said, "Pussy is fine."

"Right," Chastity said, as if adding it to her ledger, "Well it was really sore from earlier today. So Michael agreed to suffer with second-best."

"Shut up!" Hope said, trying to slap at her sister, but she missed. Mary noticed it didn't slow Hope's humping one bit.

"You're saying that I shouldn't put down Tabitha so easily?" Chastity asked.

"You're not... second best, Hope" Michael said. "You're practically perfect."

"Oh, I know, baby," Hope said. She rubbed Michael's head affectionately.

"I don't know, bro. Hope is nice and all, but don't you wish those tits were a bit more of a handful? And that little clit. I'm surprised you can even find it most times."

"Oh, he can find it all right," Hope said, then she shuddered as her brother did just that.

The three of them all kept going, as if they'd forgotten Mary was in the room. She cleared her throat and finally the siblings froze.

"It's just all these positions," Mary said, "What's wrong with lying back and letting your brother give you his cum?"

"Michael was really tired, Mom," Hope said, "I told him he needed release before he could sleep, but he wouldn't do it unless I helped him. You know Michael. He can be very stubborn."

Mary stood there, in a bit of shock. The siblings took her silence as permission and Hope, once again, began riding her brother. She leaned forward, letting her tiny breasts drag over her brother's chest and the two started to move more erratically. Urgently.

"Going to cum!" Michael cried. His sister straightened like she'd been shot. Her whole body trembled and her chest turned red. Then she fell forward and rested her head on Michael's shoulder. She reached up and petted her brother, lovingly.

"Thanks for my midnight treat," she said, then kissed him on the forehead. It all felt very matronly, to Mary. Sweet in a strange sort of way.
