Two of our 'regular' couples are semi-cuckold, they invite single men home to play with the women while the men watch. Not something we've done at home but R enjoys single men in clubs while I (G) watch, which I find amazingly erotic. On Saturday we were discussing her Chams experiences on Friday night and R said it's essential I'm there to make her feel 'safe' - she wouldn't be able to let herself go the way she does if she was on her own. At one stage she was in the couples room with someone, but knew I was watching through the two-way mirror. R doesn't like the word 'cuckold' as it seems a bit of an insult to the man involved, maybe swingers need another word?
