She wants to find some product.

“But first!” She said, as you began to notice a rising sensation, an uncomfortable feeling coming from your feet.

You watched in shock as your latex covered feet started rising, a pair of stiletto like heels pushing down onto the floor from your heel. One Inch... Two Inches... Three inches as the slim heel stopped moving, she lifted one foot up to and let you look at it directly, the latex seamlessly molding into it, also most as if it were part of the outfit, or you even.

“There we go, certainly fitting of a hot seductress, now what about the face?” She said, bringing your eyes back to the mirror, “A little mannish, but not too much, some good product can really bring out your femininity!”

“No” You shouted, indignant of her assessment, trying once more to free yourself. A tight grip suddenly squeezed around your cock, causing you to grit your teeth, as you also felt a teasing bite on your nipples. The sensation felt off, not like it came from your normally flat chest, but also not from the expanded latex flesh.

“Hush honey, don't want to gag you yet!” She said, stepping away from the mirror and towards your door, horrified at the prospect of being seen you are unable to resist as she opens the door and peeks out. While not yet night, the darkening sky outside and the lack of lightning cast the hallway in a gloom, not bothering your captor as she stepped into the hallway and ignored the light switch.

“Well before I waste energy trying to conjure something, lets see what your mom or sis might be holding onto,” She said as she began to walk down the hallway. To your shock, the feeling of a pair of hands kneading your ass began to spread, while a sensation of warm breathe spread along the nape of your neck, your feet, and upon your nipples.

She ignored the first door, a small closet, but came to a stop at the next one. Your sisters door stood before you, the latex succubus reaching a hand over and opening the door.

“I see she keeps makeup in the bathroom from peeking at your mind, but don't you wonder what she might have behind her closed door?” She teased you, slipping the door open and stepping in, “Why she might have some fun toys as well, or maybe another delectable outfit I could call another friend into. I know this kinkiest imp that would...”

“Stop it!” You say in a loud whisper, “I'll find you another body or something, just please go back to my room before someone sees us!”

“Mhm. To late for that I am afraid. With the effort I put into this body already, I want at least some fun with it. Besides, if someone sees you... well, the more the merrier!” She had an almost jolly note in her voice as she began to look around your sisters room. Ignoring the closet you had rummaged through earlier for the latex outfit, she glanced through your sisters drawers, sighing a bit in disappointment as she failed to find anything more then panties or, ew, a simple silver vibrator.

She brought you over to the mattress, lifting it up a bit to see if anything lay hidden, before dropping it back down and looking under the bed. You yelped as the sensation of your rear jiggled, hoping that it was just the latex, and a quick wet sensation licked at your rosebud. It was followed almost immediately by a sucking sensation on your toes as your cock felt a grip again, a sensation of a soft hand beginning to run it up and down.

“Oh ho! What do we have here!” She said, grabbing hold of a cardboard box, “Let's see what your sis stashed under the bed.”
