Her name was Sharon and was a medical student, one of the toppers in her class actually. Soon we were sitting close to each other rather than opposite...and would prank each other. We exchanged numbers but only had talked like friends.I was getting attracted towards her day by day. So one fine day (it was a Tuesday) after spending around two hours in the library we walked out together. I was heading towards my flat whereas she was going to her pg (paying guest facility).We walked side by side. To make things even more difficult, I gave her a time line she had to follow. "You will work out for exactly 1 hour and then you will have 15 minutes to shower, dress and put the plug in. I will know if you shorten your workout any, so don't even think about it. I will expect you back in exactly 1 hour and 30 minutes, (knowing it takes between 5 and 7 minutes to drive to the gym). Is that clear, Slut?"A meek, "Yes sir."Taking the plug and a small jar of Vaseline and stuffing them in her purse,. The sunrise was stunning and I was rapt in awe when I heard someone behind me and vice-like huge hairy hands clamp me on the wrists. “Got you,” he whispered harshly into my ear. “Don’t struggle.” Of course, I did and before I knew it, I was face down in the wet dew of the grass, my arms behind me, my boi-pussy in the air and my wrists bound in wire-ties. The fall knocked the wind out of me, and I lay gasping for breath. Finally filling my lungs with sweet air, I prepared to scream, but he. I froze."You give up?" He started tapping the huge purple knob of his cock against my chin and lips.I didn't say anything. I didn't know what to say. What do you say when one of your best friends kneels on your chest rubbing his dick against your mouth and you see the precum starting to ooze from the tip. "You don't have to say anythng. Just open your mouth." He leaned forward a little more and wiped the precum on my lips. "Open wide."I wasn't going to do it. I wasn't gay and nobody could make.
