Kim wants to stuff you two in her panties

By: Cheese111

"Quit screwing around and help us!" Becky shouted up, but Kim wasn't responding to her anger at all. Instead she walked over with her hardening cock in hand and a smile on her face. She hovered the huge column close to the house's entrance and spoke with a voice full of glee.

"What's this? Little Willy's ex has come to vie for his love? She better be able to compete with Big Willy."

"Ex?! What the fuck are you talking about?" Becky spat back, but Kim was too absorbed in her little game to care. She swung her cock forwards, the heavy bulbous tip slamming into your girlfriend and knocking her over. Before you could jump in to assist the huge mass came down on her chest, smothering her completely underneath warm, throbbing cockflesh. Your sister lazily swayed back and forth, dragging the smelly head over your girlfriend and rubbing her scent into her.

"Kim! Stop! You'll hurt her." You cry out, pushing against the immovable mass, but Big Willy only moves as Kim wants it to. With a bit of a huff she chides you.

"Oh don't worry so much. I'm not gonna hurt her. Big Willy is not a jealous lover. He'll even let her live in our house. But she's gonna act a little nicer or he will have to make clear who's in charge around here." She put a finger on the tip and pressed it down a little before finally lifting her cock off of your girlfriend. Becky was sputtering and gasping a little, straining to get back on her feet. But Kim wasn't quite done with her yet.

"Now kiss and make up." She stated with a smirk as she hovered the tip close to the two tiny people again. When Becky seemed confused she leaned in just a little closer. "Don't keep Big Willy waiting... He might get... hungry..." She said with far too happy a voice for such a threat. Becky spat and cursed under her voice, but much like yourself had caught on that the only way forward is placating your sister and her cock. Reluctantly she grabbed the bulbous head, shivering as she felt the slimy film coating it cling to her hands. Becky planted a small kiss just to the side of the gaping slit, the opening rewarding her by gushing a glob of pre onto her. You could see your girlfriend's temper fray, but she held herself together.

"Yay, now let's watch some TV." Kim cheered, opening up the living room panel to let her dick inside. You give Becky a hand and together you walk into the room. But as you were walking you heard your sister reach into the room and do something. Upon entering it was immediately clear. There used to be two large chairs alongside the couch for you to sit on, but now those were gone. Instead only the couch remained and it was turned to have its back towards the open panel. And resting right in the middle of the couch, filling it almost completely, was Big Willy.

"Come on, don't be shy. One of each side, I'm sure you can squeeze in." She crowed, watching the two tinies approach her shaft. There was barely enough space for you two, but refusing isn't an option. You slide yourself onto the couch, the fat cockhead spilling over into your lap and pressing down on your leg. Becky's situation was roughly similar. Neither of you could see eachother with the huge mass in the way. Kim smirked, seeing Big Willy provide a very literal cock block between her brother and his girlfriend.

You pretend watched TV together, Big Willy frequently slipping onto your lap and not moving until you'd given it a hug or a kiss. You could practically hear your girlfriend seething on the other side. Eventually dusk turned to night and Kim let out a big yawn. "I reckon we should get some sleep. You must be tired too." She mused, looking down at the two tiny people. She'd never dreamt of this even being possible and now she had two playthings for herself. Not to mention the ability to shrink anyone she could tempt into having a drink. With a gleeful smile she got up, an idea springing to mind. She wrote in her day planner to distill some more of her cum tomorrow. But right now it was time to sleep. She looked around for some panties to make sure her cock wouldn't be flopping about too much when she stopped and looked over to the dollhouse.

"Oh little Willy. I hope you and your ex are ready." She said in an ominously cheery tone. You and Becky just sat in eachother's arms for a little, whispering encouragement. Kim's hand came in and grabbed the two of you, holding you tightly together. The lack of clothes on you made it all the more awkward as you felt you manhood pressed against her thigh.

"Big Willy has invited you over to his place for the night, it's nice and snug and warm." Kim crowed, sitting down on her bed. She lifted her cock with her free hand and placed you on her balls. "There, two nice big pillows for you. Get comfy, here comes the blanket." She began lowering her dick, gently laying it down on you and Becky before either of you could escape. Pinned between her shaft and balls, it was an eerie reminder of how you got Kim's attention this morning. Becky let out a muffled cry of frustration before giving up and accepting that she would be spending the night here. Kim slipped on a pair of panties to hold everything in place and laid down on her bed. With a sharp click everything went dark and you resigned yourself to a night in this smelly, oppressive hell. Hopefully tomorrow would be better.
