You figured Kelsi must have been exaggerating or trying to prank you when she was telling you about Alexis. You were currently the only one awake so you decided to rest on the couch while you waited. You closed your eyes for a minute, you finished moving in so you could take a quick break. Suddenly you felt something on your chest, something heavy, you opened your eyes to see a big bubble butt in grey yoga pants on your chest.
"Good morning Gabe, you and I are the only ones up so I figured I could show you your place in the world. I was going to do it last night but I didn't want to make the other girls jealous," Alexis said.
You angrily replied with "Get off of me Alexis."
"Not until I think you've learned your place," she said as she slowly pulled off her yoga pants revealing that she was only wearing a pink g-string.
"Get off of me you bitch," you replied, now pissed off.
"Did you just call me a bitch? I was just going to have you kiss my ass but now I need to punish you. What could I do... oh I know," and with that she quickly moved her ass from your chest to your face. You were unable to talk or see, you were fighting to get her off of you but she was on top of your arms, keeping them at your side. Then she farted, it smelled terrible, but something else was wrong. You were now surrounded by warmth. "What the hell? Where did you go?" You heard Alexis' muffled voice say. You began to try and feel around, trying to figure out where you were and what saved you from Alexis' mighty backside. "What the... Is... Is that you?"

As you looked around it quickly became clear that you were shrunken by something.

Alexis held you in front of her face as she looked at you, still surprised by what just happened. "Did my... did my gas shrink you?" She asked, and before you could talk she moved you back to her ass and farted on you again. This time she could feel you shrink in her hand and said "Well, it looks like we found your place in the world," she said with glee as she moved her g-string aside and forced you against her anus before moving her g-string back and giving herself a wedgie. You tried to get yourself free but the g-string stopped you from moving. You and her sphincter were now about the same size.

"Ok Gabe, your going to be my new toy, and if you don't do as I tell you to I am going to make you even smaller. Now, the first thing I want you to do is..."
