Jen lay there, her back against the door, her new body laying on the floor. It's massive hair and muscular frame struck her with awe and fear, she had just lost her dad, but he was still here, attached to her for all time. She looked over the monstrous body she now possessed, lust pressing against her mind as her gaze fell upon her massive cock, the head of which was laying against her perky breasts.
She took a deep breath but was startled by the fact that her lower half's chest was the only one that took the breath in, she swallowed and felt it go through her body and down into her lower body's chest.
"I'm... just an extension?" Jen said nervously. "I guess that makes sense, my waist is at his... my body's neck. I guess everything up from there is like my throat and head."
Her thoughts fell upon her new sex, and she finally got the courage to touch her new cock's head. Upon her slight caress it stiffened a little more, bringing it's tip just inches away from her mouth.
"Woah.... huh this thing is hu.. huge. I'd better not um..." Jen stopped as her lower body moved, her new hands touched the base of her cock.
"Oh... no no no... no you don't Jen." She stammered, but the lust was uncontrollable, and she soon found her strong and muscular arms were wrapped around her cock, rubbing, its head pressed against her lips. It was as if she couldn't control her lower body for a moment, her instincts taking over, finally giving up she opened her mouth and took in as much of her tip as she could, her feminine hands rubbing the the rest of the head. After several minutes she gasped in a deep breath and cam, the sensation like no other she ever felt, she swallowed her semen for what felt like hours. Finally coming to an end her cock finally relaxed, softening and shrinking, settling down to a flaccid two and a half feet.
"Shit, it's still huge, how the hell am I gonna wear.... oh, yeah, I can't wear pants." Jen said, "Well, I better try to stand."
Jen moved her legs, and tried sitting up, finding it absolutely natural, her sitting height seemed to be her original standing height of five feet. She got up, her head nearly brushed the ceiling, looking down she got a light sense of vertigo.
"I better look at myself." Jen said, she started walking, the weight of her body causing her to stomp even walking lightly, she heard every step she made going up the stairs and into her father's bedroom. When she entered she found that it had completely changed, it was her's now, and looking over her surroundings she found that she now worked out a lot, weight sets filled the far half of the room. A massive bed, braced with steel for her weight sat in the middle of the room, she looked to her left and was a full body mirror, and gasped at the enormity of her body she could now see.
"God... I'm huge!" Jen started to cry. "I don't want to be huge like this!"
Just standing there her body looked like it was flexing, she did a classic flex and started crying harder, her massive pecs pushed themselves outward proudly, as if to gloat in the fact that she now owned them. She sat on the bed and just stared at her monstrous body, every thought turned on her, either about how she needed to work out now, or how hot she was in her own eyes. Lust flooded her mind once more and her cock stiffened to it's full length of four feet, she couldn't bring herself to rub it. Her nightmare had just begun and she already felt it was like an eternity. She didn't look down for the rest of the day, trying to to acknowledge her new form.
