Been sharing my wife with my brother for years, since before we got married. It's been hot and stable and fun, no drama or jealousy or anything.

My wife and I are planning to start having kids soon, and we've all been tentatively "joking" around about the possibility of having my brother help with the baby-making, too.

Like, not explicitly trying to get him to be the one who knocks her up or anything, just... she goes off the pill, and we both just keep pumping her full of cum until she's pregnant. Leave it up to chance who the actual father is.

It's a hot idea, but I'm worried we'll regret it if we go through with it.
