You were very mad, and hungry after the other people at the party stole your food, but you also felt a mix of horniness as you were still wearing the costume. As you remain in the pool, the other six tentacles wrapped around you were still flat, but you feel the tentacles your feet were inside begin to fuse together.
Not only that, but you feel your own genitals shift, as the penis get sucked into your body, while your face becomes feminine, and your eyebrows, nose, and voice become smaller, while your arms get thinner. Body hair sheds off of your body, and onto the pool as well, while your hips shrink, but two round lumps only stop growing, until they reached A-Cup sized. The hair on your head extends, until it reached the bottom of your back, meaning you were getting ready to eat, or shove something up you, as your penis was now gone, and replaced with a slit.
