You were about to get into another session of furious pounding when the doorbell rang. You huffed in frustration, a sound that matched up perfectly with your horse ears, but your boyfriend reluctantly puts a shirt on to hide you as he goes to answer the door.
You couldn't see who it was through your boyfriend's shirt, but it did little to dampen the sound of the ensuing conversation.
"M-Maddy? What are you doing here?" Your eyes shot open with fear. Maddy was your older sister, and you didn't want her knowing about any of this.
"Who are you?" Maddy asked. "And where are Chris and Allison?"
You held your breath, trying not to be noticed as Maddy pushed past your stammering boyfriend, who used to be Allison.
"Umm, well you see..." He filibustered, trying to think of an excuse to make Maddy go away. There was a fumbling sound, before he asked "Hey, why are you taking your clothes off?"
"I haven't been in control of my own body in 2 days!" Maddy cried. "I drove over here from the next state completely out of my own control."
That was when Allison's shirt began to come off.
You whispered, "Babe! What are you doing?" to which he explained that he seemingly lost control as well. Maddy became incredulous when she saw you.
"Who the fuck is that? Was she under there the whole time?"
"Hold on, I can explain," you said, swinging your leg over to face her. You were seemingly the only one in control of yourself as both Maddy and Allison were unable to stop themselves from disrobing. Maddy finally stood up straight when her socks came off, and that's when you realized "Wait, did you get shorter?"
That's when Allison's dick started getting bigger. He quickly pulled your nightgown off of you, exposing your private areas, before pushing you as far down as he could. His dick was prodding deeper than it was before, but you somehow took all of it. You realized too late that your insides were adjusting around his dick. Soon enough, Allison was poking at the inside of your chest with his dick, but that wasn't enough.
Maddy watched in horror, completely unable to escape the situation, as a hole began to form in between your boobs. First, the spot tenderized itself, until eventually it began to form a hole, kind of like the donut hole that was your ass. Once it was just big enough, Allison's dick pushed through.
This was the first time you had actually seen his behemoth of a dick, and you saw what was keeping you from detaching from him. It looked like a napkin ring had formed underneath his skin. Although you couldn't physically see it, the ring had softened.
The final step was here. Allison began to approach Maddy. He had been at a loss for words this whole time. Maddy turned away from Allison, still unable to escape. She might have gathered what was about to happen, but it was such an absurd situation that she couldn't possibly believe what was coming. You had to admit though, Maddy had a nice back and an appealing booty.
If you still had your own dick, you would've also wanted to impale her ass on it like Allison did. She raised her arms up while panting fearfully, and he lifted her up by her thighs, separating her legs. He raised her high above you, aligned her asshole with his dick, and placed her on top of it. The softened ring on Allison's dick slid through Maddy's asshole before quickly hardening again, preventing any exit. Maddy cried out in pain as she became a part of the situation you and Allison had lived for the past two days. Your head rested on her butt as she slid down and came to rest on your tits.
