Finish up an experiment

Penny finds you paralyzed with pleasure, the necklace clenched in your throat.

“Liliz zis ish not proper! You knov zat ze pill ish for ze Organization. Shpit zat out right nov!”

She draws the necklace out glaring at you and you feel so small “Sorry Dr. Von Shtupper.” You can’t even look at her. She lifts your head “Come on mein sveet little schissy. Zere is much vork to be done.” She produces a stoppered vial and syringe smiling. You’re surprised how quickly she has forgiven you, you could have ruined everything!… “What’s that?” Her smile widens “Zis ish ze lazt doze of ze vacchine und it ish all for you!”

Penny is going to let you choose any of her remaining subjects to fuck into a sigma! Not only forgiveness, but a wonderful gift? She is too good to you! You scan the options and see that she has been busy, not many uninfected subjects are left. That wily slut! Still it’s no time to look a gift horse in the mouth. She’s offering you a great gift and a wonderful opportunity.

You choose Miles, you’ve had your eye on that boi for awhile and the thought of finally having him is thrilling you to your core. As cute as you find him you’re surprised that Penny hasn’t had her way with him, but maybe it’s true that beauty is in the eye of the beholder. You watch Penny give him his shot in breathless anticipation. You can’t wait to give him a shot of your own! But Penny insists you wait until tomorrow to let the vaccine do it’s work. Being delayed when you’re this close is so hard!

You need to pop his infection cherry, now! However the door is locked and there’s nothing you can do about it other than beg Penny and she turns you down flat. That’s how you end up spending the night jerking off furiously thinking of Miles. You want him to make you pant like a bitch in heat as he fucks you doggy-style. You want to watch his cock dribble cum on his belly as you fuck him missionary. You want to climb him like a stud mountain and fuck yourself on him Amazon style. You want to infect the fuck out of him! Then you’ll fuck your new sister and enjoy the sissy difference first “hand”. You blow another titanic load of steamy sissy cum. Gawwwwd!
