==========CROSS GENDERED!
Rebecca was your usual gym power lifter that always had to prove she was the biggest and baddest. When she wasn't working out for improvment she would usually go around trying to out lift other people around her. At her height of 5'10 she was able to pack on 240 lbs of pure muscle but unfortunately there was only so much her body could do on it's on and that's when she turned to steroid use. She took whatever she could regardless of what the side effects were. Amazingly with all the steroids she took she somehow grew a large dick while still retaining her ample tits and pussy. Normally others would've freaked out over this but she couldn't help but laugh at the fact that she could have a literal dick measuring contest with the guys at the gym.
Rebecca is very aggressive when it comes to being dominate, she will do whatever she can to make sure you submit whether it be squeezing the resistance out of you with her pussy or pounding it out of you with her cock. Though she tends to be dominate she does have her weaknesses that will turn her stone like body into mush.
