After 4 years in our relation I suggested my girlfriend that I would love it if she would be dominant over me. Since february 23 we had our first 'threesome' where I was only watching. Since then I admitted that I was fantasizing about being her cuckold. She didn 't know about this so I slowly explained her and well here we are. The next step will be a big one but she is open to it...any helpfull advice always welcome.
