The two little ones looked at themselves and Harry looked down and patted "his" crotch and then said with a lisp "Mommy why i'm a girl?"
Karen said "Well Erin-"
Harry said "I'm Harry." she looked to her side and saw a baby and said "I think that he's Erin."
Karen said "note to self... regression ray changes gender... also regression affects people differently... I'll see what I can do. You may be young but i'll see what I can do about you two genders... and I also have to watch over you two. May be mentally mature but physically... Also may need some formula for Erin... or maybe find some way to make myself start lactating..." After some thought she brought a lot of pillows and blankets along with the T.V. in the basement as she started tinkering with the ray. After a bit of tinkering she had managed to change it to what she thought was a gender changing ray. Probably a bit better of a prank than the regression ray in some circumstances, and may be fun in bed. However who should she test it on?
