(you can view this a number of ways, a cautionary tale, a lucky escape, it could've been fun)
This took place maybe three or four years ago, so around 2013.
I was on a site much like this one, in that it was geared towards bondage lovers, alt.com for those wanting to know.
I got talking to a girl, a young girl, late teens or twenty one at the most. She was in a relationship, she enjoyed being tied up and played with (of which there are many variations to that theme) by her twenty something fella. It wasn't full on Master/slave, no collar or contracts (because it can go that deep) but he always tied her. We talked, shared experiences, and generally got on. It was good to make a friend. I've no idea (anymore) how, but we got around to discussing the possibility of my joining them for play. I'd never tied anyone up, and she'd never played with another girl. But the more we talked, the more excited about it we both got. A rough plan was made, with his approval. They didn't live together, he lived alone but she still with parents. I'd go to his place, to find her home alone, he'd of already left for a pre-agreed length of time. I planned to arrive dressed the part of a girl in charge. Tight jeans tucked into army boots, a long sleeved white shirt, maybe even a tie. I would tie her up, likely stripping her either before or once tied, gag her, and then enjoy her. I'd decided to hogtie her, stripping her first, and using an open mouth gag so we could still kiss. At the pre-agreed time, hopefully worked out to give us girls two hours minimum together, he'd come home to 'catch' me playing with his girl. He'd obviously (I would only offer token resistance) overpower, tie up and gag me, making me and her his captives. We'd discussed some things that he could then do. He could fuck either of us, especially liked by me was being forced to watch him and her whilst I remained tied right next to them. I wanted him to ungag her, so she could taunt me (she'd remain tied) whilst he played with me. Regardless I'd be untied and on my way home before bedtime.
We floated possible dates, and were close to it actually happening, when things changed. She'd gotten herself a new job, and worked until dinner time most every day. Maybe instead of what we'd discussed, I should still turn up but now to be greeted by him. He and I could wait for her. She really liked the idea of coming home to find me in the house, already tied up naked and gagged, like a helpless little gift from him. She wanted me tied up spread-eagled to their bed. I could still tie her up, then him tie me as per the original plan, but after they'd both had some fun with me. This all sounded equally fun to me, loved the idea of watching her come in her (well his, but she shares it) bedroom from a prone position trussed up naked on her bed. I wanted to see her smile when she saw me. I was in.
Approaching the day I had a mail, from him. A confession. They'd broken up it seemed. But the alt account had been made with his bank (or something) and so he'd kept it. The change of plans had been his doing. Trying to lure me in. He gets to tie me up I guess, get me all helpless, and by the time I enquire about her arrival it's to late I'm already his captive. No going back I guess he hoped, or that by that point, all trussed up naked, possibly more then slightly horny, I'd forgive him the trick and allow things to continue. I replied, I thanked him for his honesty, but the trust had been broken, and so I walked away.
I did admit to him (in my mail) that a part of me would've loved to of been played, to of been genuinely tricked into bondage. I think that's a near impossible thing to achieve, given the trust involved. At times I do find myself wondering how it would've played out. How would I of felt, tied up naked in some tight position, likely gagged, almost certainly completely helpless, as he told me that his girlfriend wasn't his girlfriend anymore, but it's alright, because now he has me.
