Use Your Sisters Instead: EP7

"Michael is this true?"

Mary heard footsteps echoing down the hallway.

"No way," Chastity said. She stood behind her mother, staring in wonder at her brother and sister on the bed.

"I'm sorry, Mom," Michael said, "I was in my room and feeling, you know. I was going to start rubbing but I know that's wrong. And then I thought, well, doesn't this solve the problem completely?"

"Well..." Mary said, starting to feel herself pulled towards saying yes. I mean, I guess I should be proud of the boy in some way.

"M... Mom?" Hope asked.

"He's not hurting you now is he?" Mary asked.

"Oh GOD no," Hope said, "Though he is... uhn... neglecting his lubrication duties."

"Sorry, sis," Michael said. He let go of her hips and started massaging her breasts.

"Oh, that feels great, Michael," Hope said, "But I'd like it if you touched a little lower, too."

Michael obliged. He took one hand and started rubbing between his sister's legs. She moaned appreciatively.

"Well as long as you're not hurting her I guess it can continue, for now," Mary said, "Just don't do it every time."

Given permission, Michael and Hope seemed to speed up. Their movements became more frantic. The sounds of their sex grew louder and less restrained. Instead of just lying back, Hope moved her butt up and down to match her brother's rhythm. Her sex hungrily stretched around his cock.

"But Mom," Chastity said, "It's not fair that Hope gets to fuck Michael and we don't."

"Yes," Tabitha said, "It seems like something we should each get to experience."

"I don't know..."

"It's OK," Hope said, her body bouncing, "OH! So good! Michael c... clearly knows how to treat his ssssssiiiiiisters."

"Fine. It's agreed," Mary said, "Now let's give them some privacy." She herded the two girls into the hallway and carefully closed the door behind her.

As she walked down the hall, she heard the telltale sounds of the siblings' shared crescendo.
