Not sure if I'm a Cuck or Not? Pls Help

My Girlfriend and I swing, with Women and Couples, but Really Get's me off is her going out to Meet other Men. Then coming Home Filled up. It's almost the only way I can get off sometimes is to have sex with her Used Pussy.

Am I I Cuck??

yes you are cuck...and this is what you and your girlfriend would be serving....my cock
22 hung bull 9 1.2 inches 3 inches wide

yes, you might be...

Yes and no. The term cuckold was originally used to describe a man/husband whose wife fucked other men instead of him, and he either could not or would not do anything about it. If another man made her pregnant, she would have his baby and the cuck would raise it as his own. The cuck wasn't expected to like it but it also might be his only way to find sexual excitement in their marriage.
The other similar situation is a "hot wife" - whose husband wants her to fuck other men because he/they find it exciting for both of them. In that case he is a willing player although he might not get to be directly involved at all or may just watch her being fucked by another man or men.
You can decide which applies to you the best...
