Dear Ed,
You are tied spread-eagled to the headboard and footboard of a double bed. (Don't ask me where the bed came from; I think we need the room for this one.) The bonds are pretty loose; you could probably free yourself if you tried hard, but it's more fun to play along with the scene. You are already naked; I am doing a striptease to the music.There is a knock on the door. You look frustrated. I ask, "Who is it?" through the door.
"It's Nancy," comes the answer. Your frustration at the interruption turns to astonishment as I open the door for her.
Nancy comes in. She sees you and says, "Ooh, he looks nice."
"Yeah, I think so," I respond.
"What the hell's going on?" you demand. I sit down on the bed and lean over to kiss you. By the time we break off, Nancy has taken her shirt off. You don't seem to have any more questions. She finishes undressing, with you watching every more. Then she comes around to the other side of the bed from where I'm sitting, and we both cuddle up to you from our respective sides. We nibble on your ears, run our hands up your inner thighs, lean down to suck on your nipples, and basically tease the hell out of you. Your squirming and noises are most interesting and erotic (to me, at least).
I lean over your chest and whisper something to Nancy. She takes a moment to consider, but then turns over onto her back and lies so that her torso is propped up by your rib cage. Taking a deep breath, I crawl over from the other side of you and start to suck on her nipple. From what I can see out of the corner of my eye, your eyes almost bug out of your head. I do this until the position gets uncomfortable (the arms supporting me are going to sleep) and then stop. To my surprise, Nancy askes to do the same thing for me. So we reverse our positions and she starts to suck on my nipple while you avidly watch all this stuff going on right in front of your face. It feels so good and I arch my back to push my breast toward her.
But my nipples usually can't take much of this level of stimulation. When I have her stop, it seems like everyone has reached the point of being tired of teasing. Nancy kneels over your head and gives a demonstration to you with her fingers of what she likes in cunnilingus. I start to go down on you, probably distracting you from Nancy's lesson, but oh well. It's the first direct stimulation your cock has had since I tied you, and you react very well.
Nancy decides to let you try going down on her for yourself. I keep sucking you for a while, but the desire in me is building up and finally I get on top of you and slide your cock inside me. I can't see your face, but the urgency of your thrusts tells me how worked up you are. Nancy is having to support herself against the wall while her hips are grinding against your face. It doesn't take long for me to come, and my contractions seem to be doing a lot for you, too.
