Boyfriend's Dad

During the summer I was round at my boyfriend's house. His father was in the garage working on his classic sports car and I was really horny.
I tried to get my boyfriend to fuck me in his room, but he was too engrossed in his computer game.
I even rubbed my bare pussy on his thigh, but he said he was at a "critical part of the game".

Frustrated, I went downstairs and through to the garage where I saw my boyfriend's dad under the car.
I couldn't resist and walked over to feel his cock through his grubby jeans.
Unlike his son, my boyfriend's father wasn't too busy to get some pussy.
Ten minutes later after sucking on his cock, Mr B was fucking me from behind as I lay over the boot of his old sports car.
Even though he didn't last too long, I was super turned on and had two orgasms in quick succession.
He pulled out when he came, spurting his cum all over my arse cheeks.

When we'd gotten cleaned up, I told Mr B I'd really enjoyed him fucking me. He responded by telling me anytime I wanted a Daddy cock, to message him.
We swapped numbers and since then we've had sex pretty much every other day.
I still have sex with my boyfriend occasionally, but I now much prefer his fathers cock.
