Jerk off fantasy

The other day my wife restated a fantasy after I was talking MMF threesome, yet again, that the other guy suck my cock. In past fantasy sex talk I said no, but this time I said yes. She got so fuckin’ hot from that the answer from now on will be yes. She’s really only ever gonna talk about it and not ever do a threesome but I’m curious from those that have, in that situation, has a guy sucked tour cock? If yes, was it hot?
 
Never have touch another guy but I like to while he is looking and commenting on my wife.
I suspect if another guy lets you touch and jerk his cock it won't be long before he's playing with yours too. After the two of you get more comfortable playing with each others cocks and balls the next step is suck each other. That's the way I became a cock sucker, so glad we did.
