My Little Sibling Family's New Shrink Ray chapter 10 by copier · original author: tpdbeech

Steve looks deeply at the gasping Lisa. It’s clear she won’t last what he had planned, especially when there’s fresh meat upstairs. “Fine. Do be careful, I’ll have to unshrink her tomorrow.” He dumps the tiny into his eager son’s hand. Derek clutches his new toy and strides past his father on the stairs.
“Wow! Thanks Dad!” He whispers as he turns a corner to his room; locking the door gently.

Derek’s room is typical of a male teen; messy and with a stench of unwashed clothes and dried spunk. At Lisa’s tiny size these smells were much more potent. She convulses in Derek’s giant fist, holding back vomit. Derek pays no heed as he pulls down his lounge pants exposing a semi-erection in his briefs.

He wafts his new toy in front of his bulge, dragging his helpless sister across his hardening member. Lisa screams in protest as her hair is knotted and soaked from the musty brief sweat. Derek lets out a throaty laugh. “Hah, don’t think that’s all you’re getting! You’ve been a real bitch to me. Now it’s payback.”

Derek tosses the tiny onto his bed. He watches with glee as Lisa tumbles ungraciously in the creased folds of the bedsheet. Her naked form twisting and tumbling. Derek takes the opportunity to slip off his boxer briefs and stand proud ad his member sticks out to attention. The colossal mass casts a shadow on Lisa as she looks up at the sadistic brother.

Derek smirks as he grips his cock and pumps it gently, trying to get it hard. “Hmm it seems that the ‘big guy’ isn’t ready yet. Oh well I’ve got a fun idea to start the games!”

With that Derek turns; his ass looks like an incoming meteor over Lisa. She quickly gets the message and makes a run for it. Spluttering as she goes, “oh Jesus, oh fuck! Nonono!”

Her efforts are in vain though as Derek plops on the bed his ass impacts the tiny; engulfing her in his hairy anus. Lisa’s world is plunged into a smelly pit of despair.

Derek meanwhile plucks his meat vigorously as he feels the tingling sensation in his ass cavity. The absolute dominance of his older sister gives him such bliss as he bounces on the bed harder; grinding Lisa further.

Just as things seem to be the end for Lisa; suddenly, she is released from below Derek. He stands above her, his cock standing to attention and ready for action.

“Now then sis. What shall we do together?”
