Either you wear what we offer or go home like that. Completely up to you.” I couldn’t believe what I just heard. So I asked what they had for us. ...hey produced two pairs of see through thongs and two bras that were at least DD’s. Checking out the two chests that were doing this to us, I believed they belonged to them. “Let us discuss this for a minute ladies.” After a couple minutes we had agreed that some cover is better than none. We grabbed the little things and slipped them on. I instantly. It was past midnight and every one else in the house was fast asleep. Except for us, we were too busy making sexual passes at each other. My God, and this was my sister.“I don’t know, it seems kind of weird since you are my sister.”“No one is going to know and besides I can tell you want me too as much as I want to.”I really did want her to touch my cock. In fact I wanted more. I wanted to touch her all over and fuck her so bad it made my balls ache.I didn’t say anything else. I really didn’t. I was told to stand and put my feet in the box and she fastened the box so that my legs were spread apart and unable to move. Next, she had me put my hands behind my back and she fastened them together with something."I put you in this position so that you can't move around too much." Sue said. Then she grabbed some scissors from a nearby table and proceeded to cut away the paper gown. This left me standing totally naked in front of her. My feet were in this wooden box so it kept my legs. My sister sleeps like a log. I however am a light sleeper, waking up at the slightest of sounds. Like any other night, my tossing and turning was no different, but this time, I was certain I heard something at the foot of my bed. Feigning sleep, I watched as a figure searched thru my dirty clothes hamper and pulled a pair of soiled panties from it, pressing them to their nose and mouth, smelling my womanhood. As my eyes adjusted to the light, I realized the figure was my dad. He had his cock.
