Ok, this happend last Friday. I am gooing to use fake names for my friend and her bf, so we'll call them Cathy and Dave.
Dave has been wanting to tie Cathy to another girl for a long time now, and she asked if I would go along. We're close, and she ties me sometimes just for fun. I told her I would, so we all agreed we would do this at my place this past Friday.
So Friday comes, and they show up. Dave decides he would really like Cathy and I to be tied face to face. We would really like for him to get a clue. He settles for tying us back to back. He also would like us take off our tops. We would like him to stick with the plan. So he ties my hands behind my back, and ties my ankles together, then ties Cindy the same way. Then he tied us together at the waist, so we could try to untie each other's hands. He also tied our legs together.
We couldn't get free, but he didn't help matters by tickling us. After we were untied he wanted to do it again, but this time without tops (see a pattern?). We said no, and they left. My friend is so not wanting to do this again (tho she might still tie me for fun, maybe).
Sorry it's not as adventerous as other stories here, but this is all I have right now.
