You lay the girl down on your bed and snuggle up to her making sure to be close enough for merger to occur. Your little sister bangs on your door but luckily you locked it. You ignore her the shift will happen any moment now.

Suddenly you feel your body shift on it's own, it must your two bodies becoming one.
Once the feeling stops you get up and admire your new look in the mirror. You are an even hotter girl than before. Wait before ? Must be some of her memories... At least now you know how to piss and wear a bra.
