You were Rosalind Potter, Harry Potter' older sister and you were 17 years old like your boyfriend Fred Weasley, George's twin. You and the Twins were bestfriend since first year but you kissed Fred in sixth year in a kayak at night off curfew, sine that day you both were together.
For long now you had a baby fever, you were young, 17 years old, still in Hogwarts so you never told Fred you had a baby fever because you didn't want him to think you were crazy for wanting a baby but one day you finally decided to tell Fred and he told you that you both could try... He wasn't against that.
So now you and Fred were feeling hot and in the mood so you both go in his dorm, Fred locked the door and start to take off his pants, revealing his boxers while you took off your sweater and pants, staying in underwear.
"Boom, magic."
You said and Fred took off his shirt, throwing it on the floor as he walk toward you while saying:
"Oh the real magic is about to happen."
Fred said and kissed you as you giggle against his lips, kissing him back with your hand in his hair as he start to back you up to the bed, it was gonna get serious.
