I submitted a follow up to an earlier submission and left this part out. Hopefully it will be posted the same day or the next day.
I forgot to add to my earlier follow up what else my neighbor and I have done to heighten the experience. From talking we learned we had both photographed our wives in explicit X-Rated digital pics years ago and we both still have some prints of those shots. We agreed to share them with each other privately. Now when he is jacking me off, I'm holding a picture of his wife in my hands looking at her pussy and breasts as he is telling all the kinky sexual things she used to like to do.
As I am jacking him off he is looking at my wife's spread eagle pussy and breasts and I tell him all the nasty things she likes during sex.
This has added a really fun dimension to our masturbation sessions. I really like seeing and talking to his wife now and sometimes find myself getting a woodie because I know what she looks like naked and spread wide open. Wow she has a super hairy pussy! When he is jacking me I tell him how badly I'd love to lick and suck and fuck her and vice versa. It makes us both cum in minutes. Our wives would kill us if they ever found out!
