I've always wondered what it was like to be tied and forced to cum over and over again without stopping and forced to cum again, but that has always been like deep buried dark fantasy, because my boyfriend as sweet and charming as he is ,really isn't the aggressive and dominant type don't get me wrong I love him just the way he is and I wouldn't change him, I was getting drinking wine with my long time bestie, and one conversation led go another and I told her about my deep dark fantasy and she told me how she was forced to cum 10x without break's or slowing down by her boyfriend, and she's been in to bdsm and post orgasm torture, I don't know if it was the alcohol or something but I kinda told myself doing anything with Nina my bestie isn't really cheating cos I've known her basically all my life way before I met my boyfriend,I already know she had all sorts of sexy bdsm toys in her drawer but I was never the type to pleasure myself so I never had any interest in sextoys, I jokingly said id like her to show me but only if she promise we use a safe word, and we both agreed the safe word would be apple juice, I thought she'd take it as a bad drunk joke but she replied "okay" and sat there not really believing what was about to happen, she brought out the cuffs first, and it pretty cute and in black and red, next she brought out a gag and blindfold,and I didn't realize it yet but that gag would almost cost me my life, the she brought what I thought was a cute lil dildo and I laughed, she smiled back at me and say may I blindfold you? I reluctantly and awkwardly said yes, but be honest I was scared sh*tless and I didn't know what to expect. Next she cuffed my hands and and feet to the four corners of the bed frame, and that was when I knew I was about to really happen. From the moment when she interested that toy in me and secured it in place with some type of harness I felt the warmest feeling in my pussy, when she heard me whimpering she smiled and said "this is just the low settings and you're almost ready to cum,I feel sorry for you cos, hold on a sec", she hurriedly gagged me and continues her statement, were going to be here for a while, get ready" and like that I felt like fireworks in brain for what felt like a lifetime, i was coming from the moment she turned it up to the max setting for vibrating and thrusting and rotating somehow inside me, after my 4th or 5th orgasm I tried to say the safe word but the gags and the involuntary spasms all over my body, but I couldn't say the words or she just didn't care she let me there like that for 10 mins I was crying real actual tears after 3 mins and 6 orgasms, I was trying to say it but and she just ignored me completely and was looking at her phone where she looking at her stopwatch app, after I showered and was able to walk cos most of the muscle spasms were gone, I told we have to this again and made her promised my boyfriend will never find out about it, she did and this has been happening for 4 weeks now, she's ready to take me to 15 mins next weekend.
