This story starts after an evening out with one of Sarah's regular fuck buddies. It starts on Sunday morning at breakfast with Sarah myself and Steve. Steve tells us he has a few friends coming for a lunchtime bbq and would we like to stay? We agreed and spent the morning in his garden. People slowly arrived and the drinks flowed. A little into the afternoon Steve introduced us to his son a very nice looking 21 year old lad. We chatted with him for a bit and at one point he made it clear that he knew what our relationship with his dad was. Early evening came and I was in the kitchen chatting with some guests when I could see Steve's son Phil sat chatting with Sarah def made my cock twitch.

Later I returned from the toilet to no sign of Sarah so I went looking and with no surprise there was a closed bedroom door I could hear Sarah moans, at this point Steve walked past and joked he knew she wouldn't resist!

I slowly opened the door to see phils head between Sarah's legs eating her pussy I took a seat and watched him expertly lick her pussy she is obviously enjoying it.
