Hot girlfriend and our secret that would shock friends and family

Wow! I've been with my girlfriend 8 years, we have lived together for 7 and she's amazing, I've never had to ask for anything, both work share everything. I would do anything for her and vice versa. Add that she's so hot that even now if she's naked or partially clothed I get turned on. Yet try as hard as I can, never really been able to get it done sexually. Put in time effort but eventually I had to be honest with myself. A penis that is not quite 5 inches shouldn't be so bad But, when it's an inch wide, Ive measured, bit over 3 around, but when I used a thick cock sheath (with a tube so it would slide off) It all really hit home. She loved it and it was like a whole different person. I didn't mess around, talked honestly, she was open to it but unsure how and we were both really worried about friends and family. That was about 4 years ago. Few small bumps first year but it's worked and not long ago we agreed romantically, life partners we're monogamous but sexually she has an open relationship, funny how she's slightly jealous and will remind me how I promised and that my ass belongs to her only. She straight up just has sex with them, only twice that I wasn't there, only with guys who have a big cock, length isn't anything, the girth is and I can second that. She looks so beautiful having intense orgasms while a solid thick cock is fucking balls deep in her very wet pussy.
Yes my confession is very similar

Similar tale here with now wife.
I'm average sized and it was a thick cock sleeve that amped her up and the rest is history

My wife is getting warmer and warmer to this happening for us. We recently got her an anklet, so we'll see.

Lucky you
