You succeed in forcing the invader out your body.

With the remaining strength you push the boy out of your body. He struggles to stay inside of you. The struggle for control of your body continues for a almost ten minutes neither side gaining any ground then suddenly you started to regain full control of your body.After a minute or two after you thought the worst was over,you started to tidy yourself up again by first putting your bra back on and buttoning your still damp shirt (both of which were much tighter)up again. But before you could finish straightening up,you could feel something moving around inside of your body and its slowly working its way to your vagina. After a few minutes whatever is moving inside you reaches your vagina and then suddenly the boy's body shoots out from your vagina like a missile which causes you to orgasm and fall to to your knees on the floor in ectasty. A few moments later after you gathered the strengh to stand up again, you finished pulling your skirt and panties back up(which are still damp), the tome rematerializes and falls into your open right hand. With the boys ejection from your body,you can no longer sense nor feel any more foreign presences within you and you have full control of your body again.You realize that your breasts have not returned to their normal size and wonder why. As though sensing your question the tome tells you"It is a permanent side effect from being possessed the way you were for the first time.If i am stolen from you again and they once more possess you by forcing open your nipples and entering your body that way,your breasts wont increase in size again."After giving a nod in confirmation,you quickly check the boys pulse to see if he is still alive,because you would feel horrible if the boy died,even though did he try to in essence 'explore' you using your own body . You quickly cast the spell incantation and became a spirit. You then took this chance to escape into the mall by phasing though the walls. You were now unsure whether or not to go find somewhere to return to normal or if you should go possess someone and use their body either to go somewhere else or be on the other side of 'exploring' someone's body while possessing them.
