She makes you hers

"My oh my pink striped panties huh, well it doesn't look like anything else has changed so that must mean that you have always been this much of a sissy. In the spirit of the university lets have you give an oral presentation." lost in a sea of lust you don't respond to busy breathing in every detail of her.

"Did i not make myself clear, Suck my dick now." you reacted to that and leaned forward to take her majestic member in your mouth. This is the closest you have been to a real cock and the smell of it is driving you wild. You take the tip of the shaft in your mouth and make out with it flicking your tongue up and down the underside of her dick. The taste is mind blowing as your 5" member is hard as steel in your panties and you can't help but want to please it more so your commit yourself to take it as deep as you can. The practice with your 7" dildo has helped as you take most of the monster down your throat but it wasn't enough to practice this deep. You come off her dick gasping for air and go to lean in again when she stops you.

"I've seen enough of that and am disappointed that you couldn't go all the way. Let's see if your any better with your ass." You get up from your knees and bend over to present your ass to mistress. She appreciates the presentation and pulls down your panties only to see your gemmed buttplug.

"I see that you are all warmed up for me, no need for me to go easy on you then." She teases you at first by pushing the buttplug in causing a slight moan from you at which she chuckles only to grab the gem and pull the butt plug out and put it on the floor. She grabs your hips and turns you around and pushes your shoulders into the wall of the stall. She grabs your legs and puts your feet above her hear as you are now supported only by her hips and the wall. You looks down and see her 12" cock lined up next to your sad 5" and the humiliation makes you dick twitch. Slowly her dick starts to disappear as her hips are pulled back so that she can line her cock up with your asshole. Instead of thrusting into you she drops you onto her dick making you take her all the way. The sensations are too much and you cum at her insertion spraying yourself with your cum. The cum on your skin feels electric and makes you feel so good that you zone out.

"hmm i need to check something." she grabs some of your cum and tastes it.

"mmmh perfect, just as i was hoping your ever so slightly infected. Time to make you change that." She pulls her cock out and pounds back into your prostate forcing another load to spurt out your cock. This load feels even better and you can't help but moan at the sensations of her fucking you and the cum covering you.

"oh my god i am fucking your dick off of you this is so fucking hot." you look down to see what she means and you see that you previous 5" has disappeared and is now down to 2". The thought of her fucking the masculinity out of you makes you cum again with a high pitched moan.

"Wow i can't believe my brother was such a slut this whole time." She continues to fuck your ass as hard and fast as she can. Lost in the sea of sensations you brush your blonde hair out of your face before realising when did you hair become this long and when did it become blonde.

"Now you are starting to look like a true sissy, but you are still missing one more thing..." you feel her thrusting even faster now as you now just have a constant stream of cummies leaking out of your clitty.

"... A full ass of cum" You feel her massive loads of cum filling your ass as your clitty spurts like a fountain even more cummies out of you. She pulls her cock out and her load starts to leak out her cum as she bends down and picks up your butt plug and puts it back into your ass. She sets you on your feet and you can't hold your self up and slump to the ground as you are still leaking cum. as you look down you notice that your once androgynous body is now much more feminine and your clothes have changes aswell to match your new form.
