F40 my BFF went too far

Not sure I could call this cheating seen as I facilitated the hole situation...

Recently been showing off my hubby as realized I had a cheating or cuck wife kink...

My friend had recently talked about her bf been a let down and that they had split up and so she had been running on dry if you know what I mean lol...

So I offered his services,told her about his kinks,and what drives him wild,we were toying about the idea of me watching and arranged meeting for a drink...so I told her I was in my way just hijacked the shower from hubby and wouldn't be long...didn't get a response but headed out anyway.

I'd had a few drinks and decided to call her,she picked up and said she had been held up and couldn't really talk as she had her hands full...turns out she also had a mouth full....5 mins later I got a picture of her...with a caption asking if this what I wanted to see....

I had agreed that she could blow him as long as I was there but when I opened the door and let myself in,she was on all fours,her tiny ass in the air,I could hear the wet,slow slapping as I crept up the stairs and I could see the reflection of her in a mirrored door in my room,there was my husband,fucking her rough,hard,slow...God she made a lot of noise and I could hear him moaning and grunting as he fucked her...I stood shocked watching...furious but excited...what should I do xx
