Yes, all the partners I have ever swung with and the feeling is great. If its done infront of you it is an amazing rush as the guy fucking your loved one suddenly pushes hard into her then stiffens as he let's out a grunt or groans and you know he is filling her up. I usually go straight into her afterwards as the pussy is all hot and sticky, but I don't usually last long.
Then there is the one where your partner is being fucked without your presence and she comes home full of cum, now that one is REALLY hot.
One of my favorites was when my exwife used go to parties or meets and we would get separated. I would be looking for her in great anticipation knowing she would be fucking some guy or guys. When we met up she would tell me all about it as we fucked
