[MF] pretending to be my gf’s brother girlfriend could fuck her ski instructor [Cuckold]

So, my girlfriend and I just had a little ski holiday. I am a much more experienced skiier than my girlfriend. Also her parents had booked her some ski lessons as a Christmas present.

She had a very handsome Norwegian ski instructor who was about a year or so older than her called Jan.

So, unbeknownst to me the whole week my girlfriend had told Jan that I was her brother. And on the last day of lessons she invited him to join us for some aprés ski.

We went out. We got drunk. They started making out. When Flora gets drunk she gets really horny. She was rubbing his cock through his ski trousers right in the bar. So he basically carried her and skied back to our flat.

We got in and I went out onto the balcony to have a smoke. When I turned around and looked back in through the glass door. Flora was already on her knees sucking his cock.

It is a wierd experience watching your girlfriend suck another man’s cock. This was the third time that I had seen her fuck another guy and I could feel that I was both really turned on but I could feel the pang of jealousy.
