It was your own plan, you wanted to become Kim for a day, break up with her boyfriend, leave a bunch of subliminal messages to call you at her place, and jump back to your body.
The spell worked wonderfully. one minute you were at your place, and the next you were at Kim's home, looking thriugh her eyes. You were so excited, you couldn't stop oigling your own body. When you walked down the stairs, all this excitement made you lose your balance. You fell down the stairs and hit your head on thenlast step.
When you came back to your senses, you were resting on your living room couch. A man sitting besides you. "Are you ok?" he asked. You couldn't remember who he was, or who you were. "Kim, you are scaring me!" he said. That's when you realized you were a girl. Weird, because you felt like a guy. "Sorry, I just feel weird. You say I fell down the stairs?" you ask. "Yes, I found you lying on the floor, and carry you here" he responded.
Suddenly, you remembered his name, "thanks Alex" you said. "Wait, I am starting to remember, you are... my boyfriend" you said. "And today is our 2 year anniversary as a couple" he added. And kissed you. It felt weird, like you had never kissed a man. But it was probably because of the bump in your head that you were thinking that. You kissed him back.
You unzipped his pants and gave him a hand job. That felt familiar, but like you had done that to yourself. He ripped your bluse open and kissed your breasts. Right then any random thoughts went away. You started to enjoy the whole ordeal. You ended up having sex with him right there. You still remember how good it felt when his thing rubbed your clit, and it felt a lot better when he came and filled you up.
As you both cuddle, your memories came back. "oh shit" you whispered as you realized who you used to be. But it didn't matter, you didn't want to go back, being Kim was too good to be true. You kissed Alex once again.
