The Cabin

I've had another hot dancing night at E's with you and Bryan. I've had a wonderful time but I want more of you both. Knowing you're staying in a cabin prompts me to ask you an unusual request. I say to you "I know you're not at the point of playing with others but have you had anyone watch you two have sex yet? You reply no so I ask if I can be the first tonight and would like to watch you have sex in your cabin. You seem unsure but I tell you you will be able to guarantee no participation from myself. I tell you I have a roll of duct tape in my car and you can use it to bind my wrists and ankles and sit me in the corner. You can also tape my mouth if you wish my silence during your passion. You consider briefly before going off and have a private discussion with Bryan. To my delight you agree and take me to your cabin. You pull my knickers down and lift my skirt up to expose my sissy cock to see how it reacts during the session. My hands and legs are now bound and I'm sitting on the chair in the corner. You order me to stay quiet or you will be forced to tape my mouth. Once done you focus on each other and it seems you have already forgotten I'm there. After some kissing and feeling, clothes start to come off and I delight in seeing you both naked given away by your glance at my erection. Bryan starts to do his manly thing with you and his kissing and mauling has you gasping and legs opening with invitation. Both your body heat is warming the room now and odours of your sex invade my nostrils to which I sigh with frustration.You afford a quick look over at me and smile before losing yourself to desire once again as Bryan forces his pierced cock inside you. I see the sweat start to amass on Bryans back and buttocks which I want to lick as he now fiercely fucks you. The heat and heavy panting overwhelms me as I can only sorrily look down at my erect cock and only wish I could at least wank it but with my hands tied behind my back that moment is denied me. Bryan's efforts are soon rewarded as he explodes his orgasm inside you causing you to cum too. When the panting and giggles have calmed down you come over to me, cut my tape and unlock the cabin door. You then reach into your pussy and pull your fingers out before saying "here's a little souvenir for you take home with you" and on showing me the door putting your oozy fingers in my mouth. "See you again soon Susan!"
