Sure does

Angie blinks for a second and when her eyes open again rather than looking into the previous icy blue river of her eyes you look into a sea of dark green. It seems the collar can not only make people do stuff, it can also change physical traits... You shudder at the thought of what might have happened to you if Emely did not take if off of you this soon.

"Oh myhh", Emely exhales sharply, "that color fits you very well my dear. Say dear, have you ever wanted to have bigger breasts?"

"Nah, I like to do lots of sports, so these are fine. Big ones would only get in the way with my exercising.", says the blonde with a confident smile on her lips, and you have to admit, that body looks nicely toned.

"Oh... That's too bad Angie", Emely says with faked sadness in her voice, "cause I wish you had big double D knockers, they'd really fit your blonde hair I think."

And before your eyes Angies shirt slowly baloons outward. She does not seem to be wearing a bra, which probably was not necassary with those about A sized tits anyway - otherwise this might have been painfull. Emily gasps in anticipation and you watch Angies breasts closly while they reach their specified size. That slimfit shirt she is wearing is stretched to the upmost and thanks to that the shape of her puffy nipples can be seen clearly. You can not help but feel your cock stir in your pants.

"Oh my god Angie! Your breasts! They are huge!"

Angie looks down to inspect her new rack, "Guess they just grew..". "And you don't find that strange in the least?", Emily mischifly asks. "Nah, seems pretty standard too me, although I guess I have to go shopping for some new bras. I just hope they have some supportive sport bras so I can still do my excercise."

"I see, so this is all pritty normal to you. I guess you do not have a problem with me doing this then either, am I right Angie?", Emily asks while standing up from the couch, almost jumping over to Angie and taking a hold of her Double D sized boobs. "Sure why not. Do as you please."
"Nice! Hey you, why not come over and cop a feel yourself?", Emeily directs at you.
