You wake up soon afterward, aching slightly, but in a good way. You recall what it was like to have Stacy penetrate you and just the memory is enough to send a thrill of pleasure though your diminished cock. You gently stroke your miniscule manhood with one hand while using the other to play with your plump nipples. Fun as it all was, you decide that maybe it's time to start changing things back to normal, starting with yourself.
The flashlight is on the night table exactly where you left it and you turn it on to the blue setting you know will change you back to normal, only to hesitate. You like the way Stacy has become so much more confident and sexual and you don't want to lose that. Maybe it might be better to take things slowly you decide, making small adjustments until you find the right set of changes to keep Stacy's new attitude. Still, you do want to start with yourself, more specifically, your cock.
You put the light to one of its lower blue settings and shine it on your tiny cock, watching as it grows until it reaches three inches long, flaccid. You're tempted to put the light to a higher setting to bring it closer to its previous size, but you hear Stacy stirring next to you so you put the light down, out of her sight.
She looks at you sitting there and smiles, "Playing with yourself are you?"
You shrug and she reaches out to give your nipples a tweak, "You want me to suck you off like you did for me?"
Yes, this was exactly what you were hoping for, "You know I'd love it!"
"Okay," she says with a sly smirk, "I suppose I owe it to you for letting me fuck you up the ass."
Normally hearing your girlfriend say something like that would make your stomach churn, but hearing her talk like that so bluntly strikes you as being kind of hot.
"There's just one thing I want to ask you," her smile grows, "What made you decide to play along with us like that yesterday? Even with your big, beautiful breasts you always acted like just another guy, albeit one who had to wear bras that gave plenty of support."
To emphasize this she cups your breasts in her hands and gropes them.
"Ooh," you gasp and squirm as she gives a particularly hard squeeze, "Gentle."
She laughs, not a nervous giggle, but a throaty, sexy chuckle, "Why? I think you like this."
You follow her gaze downwards and see that your cock is getting hard, "Alright, maybe a little."
Stacy squeezed harder, "I don't know, the way you were squirming and crying 'harder, harder!' when I fucked you makes me think you like it rough. So tell me, have you finally discovered your feminine side?"
"Maybe," you start to say more, but before you can Stacy bends forward and takes one of your nipples in her mouth, teasing it with her tongue and sucking on it.
"Mmmm," you moan, pre starting to bead on the tip of your cock, "That feels so good."
She gives your free nipple a good hard pinch before she takes her mouth away.
"Glad you liked it, I'll do more if you answer my question," she licks her lips seductively at you and you start thinking fast to come up with an answer to her question.
"I don't know," you shrug helplessly, "I guess I just wanted to see what it was like."
"And what was it like?" Stacy urged, a hungry look in her eyes.
You think back to the pool party with the girls, getting to see them running around topless and acting like there was nothing strange about you being there with them, "I guess it's fun."
Stacy's eyes light up, "Wow, really? You like being one of the girls?"
You wouldn't have put it quite that way, but you don't see the point in getting bogged down with details, "Yeah, that's one way of looking at it."
"So that's why you let me fuck you like that after holding out all this time, you just needed a little push in the right direction," she rubs her hands together excitedly, "This is so awesome! Let's keep it up, alright? We'll do a little role reversal type thing."
"Sure, that's cool," you say, not sure of what she means, but eager to have her mouth on your cock, "I answered your question so shouldn't you start now?"
You gesture at your cock, which is painfully hard, practically begging for attention.
"Okay, but only if you ask me to suck on your clit."
You stare at her dumbfounded, "Wait, my what?"
"Your clit," she laughed, "If we're going to pretend that you're a girl you need to act the part."
