I was getting horny and slowly I placed my hand on the guy’s thigh as though my hand slipped in sleep. I waited for few seconds seeing no resistance...from the guy I proceeded a little further by inching my hand towards his balls. Now my finger tips were touching his balls. I slowly cupped his balls and started pressing them softly. He spread his legs part to accomodate my hand I was very happy to see this reaction. I slowly kissed on his lips as his head was resting on my shoulder and he. It was a warm night I was wearing just a red dress that wrapped over and fastened at the waist with 2 buttons a strapless bra and thong with holdup stockings, the guy with the knife said what do you want us to do with her to teacher her a lesson not to take work of our girls. He grabbed my dress where it fastened and pulled snapping the buttons off he then told me to take the dress of while he cut through my bra between the cups before doing the same to my thongs. He pushed me to my knees. That pleased me as I continued to undress her, next her granny blouse followed by her chemise. I took my time enjoying myself, next came her bra to free up her generous breasts. Kneeling down on one knee I pulled her knickers down to her feet. She held on to my head as she lifted one foot, then the other to permit me to remove them altogether. I had her sit down while I removed her granny boots, then off with her stockings and garter belt. Now she was completely naked except for her smile, ear. “Karen will spend every night with you to make sure you don't give yourself orgasms when you're alone to avoid having one when observed. We will begin as soon as you have undressed and relieved yourself”. She raised her eyebrow, shrugged and followed Karen. I went into the bedroom to prepare. I already had ties attached at the four corners so I could spread-eagle her. I also had extra pillow to put under her butt. I did pride myself on my sexual prowess, but I knew this wasn't going to be easy,.
