I married a horny young devil twenty years younger than me, who needed someone to enable his addiction to extreme rubber bondage, and couldn't find anyone in his own age group. It was a little off-putting at first, but he was so cute and so pretty, and willing to be my sex slave, so I learned all about it, and expanded my role as dominatrix wife, quite happily. He is an incredibly long-stayer and early repeater, and nobody could wish for a more fulfilling sex-life. It's been five years now, and I admit I needed a change. So I went looking, and found an intelligent educated male my own age, who thought it was cool to have a sex-slave husband, and wanted to get involved. Junior was extremely homophobic, and without him being so helpless, we would never have got him trained to fellate my new friend, despite his revulsion at the whole idea. To watch my young husband, trussed up in a rubber-lined bag, on his knees, his zippered mouth-opening full of Martin's big cock, utterly unable to resist this treatment, is a real turn-on, and I make them do this several times a day, for my amusement. Martin also pulls Junior's goodies outside trough the other zippered opening, and tightens the zipper up around the roots, then he wanks (Better word than masturbates, don't you think?) him to death, never allowing him to actually come, until he's on the verge of insanity with need. Then we milk every last drop, into a glass vial, refrigerate it, and sell it to the local sperm bank, for more money than you'd believe! They also pay amazingly well for what is called "pre-cum" available copiously when the 'victim' is kept on the edge of coming for hours on end, which is REAL fun for both of us on the outside, as well as being extremely profitable! Aren't we awful? We don't care!
