Derek returned home and could smell pussy even before he saw it.
"OOoohhH fuck!" The soft feminine moan came from his roommate Alex's bedroom. Derek's cock grew hard and he crept in for a better look. Not that much creeping was required. Alex's bedroom door was open, and on his bed was a woman with her eyes clothed frantically fucking herself with a dildo.
"Oh god! YES! That's- fuck! Oh fuck, right there!" Derek was halfway to opening his mouth and offering to join in when: "Oh fuck! Oh FUCK! OOOHH FFUUUUC-" the woman spasmed and screamed as she came.
Slowly her eyes fluttered open and she saw Derek looking at her. "Oh shit! Sorry! I thought I closed the door." It wasn't the first time Derek had caught her like this, so she wasn't too mortified.
"You're certainly enjoying yourself." Derek smirked, "You're just masturbating everywhere, aren't you? The whole apartment reeks of you're pussy dude!"
"Yeah, I might be getting a little carried away here." She chuckled, "It just feels so good! Thanks so much for springing for this bodysuit for me man!" Alex smiled.
"You know, I kind of figured you'd take to it like you did. I also figured you'd love cock in you, and you clearly do. Plastic cock anyways. You ready for the real thing yet?" Derek grinned, but inside he was getting frustrated. He had the worst blue balls from days of hearing, seeing, and smelling Alex's smoking hot new body pleasuring itself. He'd been kind of counting on Alex getting so horny as a woman she'd fuck him, but so far nothing.
"Come on man, we talked about this." Alex sighed. "I totally get how hot I am now and how much you want to fuck me, but that's just going to be too fucking weird man! How am I supposed to look you in the eye after you stick your dick in me? Besides there's all those stories about people getting stuck in these bodysuits when they have sex and- what're you doing?" Alex asked as Derek pulled out his phone in the middle of her talking and started fiddling.
"You think I shelled out all that money for that bodysuit just to watch you fuck yourself? Nuh-uh, I've been patient enough. That suits got some extra features I bought that I think I've earned the right to try out now."
"What's-" Alex gasped as she suddenly started to feel stiff, his arms and legs settling into positions that felt comfortable even though they really shouldn't have been. "I feel really stra-nge." Alex's words became very soft as her skin tingled and she found it more difficult to speak. Looking down she saw the color and texture of her skin changing...
"Something about this mode causes a drop in life-like fidelity of the bodysuit." Derek said as he stripped in front of Alex. "At least that's true externally. They say internally everything still is going to feel very natural."
Alex tried to protest, but found she could no longer speak. Staring up at the ceiling, she realized what she'd become as Derek repositioned her legs. Oh fuck! Alex thought, trying to say the words but failing, I'm a sex doll!
Derek moved between Alex's legs, and Alex felt an aching emptiness there that dwarfed what she'd felt when she'd been masturbating moments ago. She was as horny as if she hadn't cum at all - ever!
I should've just fucked him. Alex thought as Derek pressed in to her immobile form.
OH HOLY FUCK SHIT BALLS MNNGDHHFGf! Alex struggled to string a cogent thought together as a pleasure unlike anything washed over her.
Alex came more or less continuously as Derek fucked her. When Derek pulled out and finished all over Alex's face, as much as Alex missed the pleasure she was almost relieved. She felt like she could breathe - even though she didn't need to anymore.
"MMm, was that so weird?" Derek asked as he looked down on Alex's plastic, spooge covered face. Yes. Alex thought, but she had enjoyed it anyways. "I think I'll let you think that over for a bit while I go get dinner. Then maybe another round or two tonight, then I'll leave you to sleep like that. Do you sleep when you're like that? I guess you'll find out. Then I'm thinking one more round tomorrow morning, then I'll turn this mode off and you can be a normal guy-in-a-woman's-bodysuit again."
Alex wanted to shout as Derek left him there alone, frozen in place as a woman and a sex doll covered in his semen, but what he wanted to shout wasn't a plea for leniency.
COME BACK AND FUCK ME MORE! Alex's thoughts roiled, horny as he'd ever been.
