Normal? theres isn't much normal about this scene/lifestyle.
but ya, you pushed the boundaries of your sexuality and are working through some guilt.
lets face it, theres a little homoerotic component and in this case some dom/sub roles in being a cuck that can take some time for your psyche to adapt to.
I see sucking dick at some point in your future. you'll love it and possibly feel disgusted with yourself at the same time. but I bet you don't do it just once.
I like getting a cuck to suck my cock sometimes. I dont buy that bullshit about men being better cock suckers because they know what it feels like though. But it sets the tone for the rest of the evening with this wife. he knows theres no turning back, and what his role is going to be...theres only 1 man in the room from that point on.
