Since i already mentioned having a live in fuck buddy if I could have anything else sexually it would be being able to continue to have sex up to the day I leave this world behind. No medical issues to prevent me from having an erection that can't be solved. No loss of libido or want to for having sex. Just to be able to enjoy and receive the pleasure I get from my sexual adventures for the rest of my life. I'm in my late sixties with a long sex life so far. But yet, I love having sex so much I never want it to stop.
I'd probably choose to have a married couple who are monogamous to have sex with me when ever we feel like it. Then I could live all just about all of my fantasies.
After giving it some thought, I've come up with a few: 1) To have my wife peg me as frequently as we have "regular" sex 2) To be spit-roasted and turned into a"cum dump" by 2 dominant Top guys 3) To have a MMF 3Some with my wife and another bisexual guy that includes DVP (Double Vaginal Penetration) and my wife finally witnessing me me bottoming for another guy 4) Being collared leashed, and locked in chastity by a really sexy Top Daddy and being "used" for his pleasure
If I could I could have anything I desire sexually, it would be to incorporate diapers into my sex life with my wife. As a long time DL, my wife realizes how important and prominent they are to me. We do occasionally engage in ABDL (adult baby/diaper lover), play, but not nearly enough as I'd like. Also, as a cuckold, I'd really like to join in with my wife and her boyfriend more frequently (I've only joined them once), even if I had to wear a cock cage (chastity). I realize their time together is all about them. I wouldn't mind"fluffing" him or eating fresh creampies. He has a nice big cock, and I think I'd enjoy sucking it, especially after he was deep inside her
I'd wish for my wife to be randy for sex. I'd like her to actually want some cock. Then I wouldn't have the need to plan/fantasize about sucking cocks with a bi guy. The reality is, she's cold and disinterested and I've all but given up.
