not given, but when me and my current wife started dating gave me a BJ once a few hours after I fucked an old gf of mine. She starting sucking on me and looked up at me and said "you have a pussy taste on your dick". What suprised me was that should could tell from the taste.
My fwb and my fb can also tell. Every now an then I will fuck my wife and then later on meet up with either my fwb or fb who is bi. She can tell and thinks it is a turn on. Fwb is never too pleased so I have to clean up first. Sometimes the pussy juice will stay on my fingers which I love smelling during the day. One day my 20 something fb wanted me to come over and I had just fucked the mrs but she didn’t know. One day I met my fwb after she spent the weekend in Atlantic City with her girlfriend and called me to come over after she got home to eat her out and fuck her. So I m going down on her and detected some dried cum around her which completely turned me on. Turns out they met some guys and she let two of the. fuck her and drop their loads. I am hard just thinking of it.
I enjoy sucking my "buds" big cock regularly, but I have to admit it is more enjoyable to do so after he's fucked his wife pussy.
