Your wife with another guy's cum

I was used to other guys cum in her since when we were just fuck buddies she was doing what ever she wanted. She would often show up at my apartment wanting more cock and I'd find her already overflowing from whatever guy she had been dating at the time. When we got married and she was getting fucked by other guys Aids and other STD's were more of a concern so condoms became the norm for any other guy that was able to get in her panties. So in relation to the original post the excitement for me came when after using condoms with other guys for years she fucked a co-worker of hers and was so turned on she let him ride her bareback the first time (and ever time after) and I was confronted for the first time in years with another guys cum leaking from my wife. It was a huge turn on to know she was so turned on she just let him use her like that and then had to drive home with his cum just flowing out of her cunt and soaking her panties. She was a mess when she got home and showed me what she had done by shoving her pussy in my face and "admitting" to me what she had done. Sliding into her was sooo hot and she was still super turned on.
I loved that her friend had figured out what a hot piece of ass she was and she was getting off on letting a guy use her that just pushed all her buttons.
 
There's a lot of discussion about a wife's first blowjob or first penetration, especially when the husband watches. Something that isn't talked about as much, but can also generate controversy, is the first time a husband watches his wife come into contact with another guy's cum.

For those who have had this experience, what was it like watching your wife with another guy's cum, where did he cum, and what did you feel at that moment?
My wife was in the entertainment business in Hong Kong when we met. Many Filipina maids earnt extra in their spare time. She never stopped while we dated and I was OK with it. I was aware of cum in her panties sometimes and I always wondered what it would be like to see a guy unload inside her.

After we were married I suggested she started taking some guys as bulls since I could tell she missed it. In the early days i used to watch and that first time I saw her wrap her legs around him as he ejaculated inside her was unbelievable. I moved around behind him to him hunch over and push deep up inside her vagina as his balls pulsed. Her eyes were closed as she kissed him and then I saw his semen trickling out around his cock. When he pulled out the sight of his big load coming out in globs was awesome.
