Thank You Wind.

It's New years day and last night we had lots of family and friends stay over . A good time was had by all.
Typically on New Years day my mum drags as many as she can out for a country walk where we live, I was going nowhere, I was snuggled up in bed with my new boyfriend. After about 20 mins all the commotion was over and a posse of people left our house.
I gave it a few minutes and felt my boyfriends cock and it was responsive, I disappeared under the duvet and gave him a good suck, he was fucking my mouth and about to cum, but I wanted to cum too and pulled away threw the covers off and quickly stripped and started to ride him. When I ride a fella it always makes me cum. We were only slightly disturbed by a door rattling every time the wind blew but that could wait.

To be honest it doesn't matter who I fuck with and how big they are if I'm on too I can cut, so despite my latest being quiet ( maybe he was hung over, uncomfortable being in a strange house) he wasn't near to cumming himself. Suddenly my bedroom door which was shut, blew wide open and I distinctly saw my father quickly move out of sight and all he was wearing was his football shirt.
I said to my boyfriend a window must be open, let's not ruin the moment and I started to ride him with renewed passion. Then it happened I could just see my pervert dad wanking his impressive cock on the corner of our landing but only being exposed through the angle of the wall mirror. I have never felt so horny,I demanded my boyfriend to fuck me harder, take me like a slut, I put his hands on my tit's, bit my lip, pulled away from him and bounced up and down like porn star. I leant back away from him and dived into my clit. Then I saw my dad cum. My boyfriend came too and I was orgasming involuntarily then all of a sudden the door slammed again.
I climbed off my boyfriend and we both laughed.
I have no idea whether my dad has watched me before ?, I don't think so.
I'm confused as to why I was so excited by it, not outraged.
