As we were finishing up the paperwork another young lady, perhaps late twenties, brushed past me to file a folder of some kind in the cabinet across t...e small area of the receptionist’s desk. She leaned over to put the document in the drawer and I got a view of her firm, sweetly rounded buttocks. I glanced only briefly, not wanting to be taken for some kind of pervert or letch, but the sight was one for the books, one to be remembered. I reprimanded myself in thought. Her hand with the rabbit in started to ram agaist the zip as if she was trying to fuck herself with it,all the time she was also pulling her jeans up against her cunt and letting go and then pulling them tight,as if wanking the zip against her self,her movements grew stronger as did my desire to run in and fuck her also,but my hand was occupied wanking me away to her, her feet started to dig into the bed lifting her bum of the bed,moving cunt up to meet the rabbit,boy this was cock tingling. Before this we’d never even really considered dogging as one it was like a fantasy and especially as we are both well into our 50s and assumed dogging was for young couples, not like us old farts but although a mature couple we still had a very active sex life and most nights would be at it hammer & tong!We pulled into the car park, no one else was around so got down to a bit of kissing and I started to unbutton her dress, once undone I pulled her bra down and started playing with her nipples. He was rock hard and his large cock was almost eight inches’ long. I could not help but touch it and he kissed me again. I could feel his dick throbbing and getting even bigger in my hand. As I played with it I could feel him leaking pre cum.I got mesmerized, as I dropped to my knees and took him into my mouth. I kissed, licked and tasted his pre cum. I did not want him to cum yet; so I begged him to lay down on the floor.I straddled David, teasing my mound with his big cock. I was now getting.
