It appeared to be a handcuff key. “Before we proceed, slave, understand that the key to your cell door is hanging from a hook out in the corridor. T...ere is no way for you to reach it from your cell, so attempting to grab me through the bars would be absolutely pointless. Attempting that will earn you a punishment beyond your wildest imagining.” With that, she lowered the ring with the key into my hands. “Unlock your handcuffs, slave,” she said.I tried and it was almost impossible. I couldn’t. Ally started to cum, and her pussy contractions made me start to feel something swelling up too. This was the second time in under five minutes I was cumming with some one right outside the door, just waiting to discover us. I was scared shitless, and almost out of bodily fluids.My sister, her job now done, sprang out from under the blanket and sauntered over to the door. Her pussy was gleaming with moisture. I whispered to her “what the fuck do you think you are doing?”She responded with,. "I knew you always wanted this to happen deep inside - even if you didn't realise it. Now don't you dare swallow because I want you to savour our man's cum!"Mike slumped back against the wall and fixed his stare on Kelly."I want you both to savour it girl! Now get on your knees and give that pussy you used to call a man some sexy kisses, I wanna see two white sluts fight over my cum!" Kelly squealed with delight and joined me on the floor. She planted big sloppy kisses on my face, but not all. You are now a cock sucker and in a fewminutes, you will be complete girl, just like me. I hope you're ready.Before I could answer, I felt Drake getting in position between my legs,and his strong hands moving over my garters has he lifted my ass evenhigher into position. I felt my heels just touching the bed, as I wasnow totally helpless.I was about to tell him to wait, when I felt the tip of his cockpressing on my opening. There was no way he was going to fit in mysmall pussy and I shuddered.
