She grabs a condom, you're going in there

By: Cheeze111

You looked up to your gigantic sister as she seemed lost in thought. She aimlessly sways you around, making you dizzy, whilst contemplating her next step. Suddenly her smile doubles in size as she was struck with an idea. She held you up to her face and gave you the good news.

"I think I know how to hit two birds with one stone here. I'll be able to keep you safe and punish you at the same time. Though you don't have to worry too much about it, little Willy. I'll go easy on you." She cooed, her tone eerily gleeful about the whole thing.

Unsurprisingly you weren't put at ease by this announcement at all. The last little bit of fun she had with you saw you exploring the inside of her dick. What fresh horrors would await this time? She walked over to the nightstand next to her bed and opened the drawer. From it she grabbed something that filled you with dread. It was a condom, you could recognize that shape easily. You had a package just like that in your wallet, in case you and your girlfriend Becky ever wanted to go all the way. But this one looked like it was part of some prop comedy act, almost hilariously oversized.

"Heh, you wouldn't believe how hard it is to find them in my size. Even the biggest offerings at the **** store are far too tight for someone like us. Thankfully mom found a supplier on the internet that could handle our girth." She chuckled a little at her own joke. You were just bemused by the whole story. Your concerns were still lingering on the punishment she mentioned before. Only when she removed the wrapper and brought you close did it dawn on you what she was planning.

"You're gonna give Big Willy a big hug while I take care of some things. And when I let you out you're gonna apologize to him for being rude, understood?"

Your slack-jawed silence was taken as agreement and she placed you on the rubbery surface of the condom. Soon your view was filled with the fleshy column that devoured you earlier, her cock coming closer at speeds. With a small squelch you are pressed firmly against the tip. It stood semi-erect, rigid enough for Kim to easily unfurl the condom around it. Your prison tightened, leaving you plastered against the bulbous cockhead. At least you were pinned tightly enough that there was no chance of slipping inside. But if she came, there'd be nowhere for her climax to go except your little prison. Hopefully her earlier release would keep such scenarios at bay, but it wouldn't shock you if she's already got another shot in the chamber, ready to go.

Suddenly things went dark as Kim slid her panties back up. She huffed and struggled a bit to stuff her cock back in, the little toy stuck to the tip providing such good stimulation. Thankfully her massive cock wasn't at full mast or it'd be nearly impossible to work it back into her panties without tearing them.

You tried to get comfortable as best you could in the oppressive environment. The damp surface of her dick was uncomfortably warm and the heavy scent of sex hung in the air. The tight rubber prison was unyielding and the constant motion was dizzying. Kim was on the move, but you had no idea what she was up to. She hummed a little to herself, occasionally moaning if you tried to struggle. It quickly dawned on you that your token resistance was turning her on. And not wanting to share the tight confines of the condom with a flood of cum you resigned yourself to holding still. Mercifully Kim didn't seem to mind. After what felt like an eternity of being stuck to her dick she finally lowered her panties again to show you the results of her labors.

"I can't have you walking around the house freely. One of us might accidentally step on you." She sounded sincere in her concern, but you didn't like her solution. "So you can live in here for now."
