My Partner Has Been Seeing A Friend Of Ours For Some Time Now,he Is Unaware That I No That There Sleeping

My partner has been seeing a friend of ours for some time now,he is unaware that i no that there sleeping together, being a little willy cuckold it turns me on hugely, ive always wanted her to tell him what i am but she hasn't as of yet,she's a bit nervous i think as we both know him, that was until Sunday night when the pair of them went out to watch the football ⚽️, she told him i wasn't to well,they spent the whole evening in the pub and when she due home i received a text saying I'm back at his place, im going to be staying out a while longer,she also said shall i let him fuck me cuckold??? I was so excited and turned on i replied straight away with a big yes please 🙏, she replied well message my phone saying hi there,I'm a little cuckold who can't satisfy her,please can you show her how a real man does it,she replied good boy,now sit and wait until I'm home, I sat waiting my heart pounding, she returned completely satisfied and excited, i asked did you show him my text??? She just laughed and said what do you think cuckold, we cuddled all night and it was amazing, she still won't answer me with a yes or a no but when i ask she just smiles and giggles at me,this is one night I'm never going to forget, plus I'm really nervous about next time i see this friend as I've no idea if he now knows xxxx
