A friend had called round to see me, and I was wearing a pair of my wifes white panties when he arrived. He walked in without ringing the bell, so caught me unawares. The look on his face was a picture. He commented on how firm and round my ass looked. I told him that I had been wanking over some of my wifes pics, and he said he would love to see them. He got his semihard cock out and started slowly wanking. As I was unsure when my wife would return, I kept leaning over looking out of the window, and he said that if I kept beding over like that he would slip his cock into me. I told him that I didn't think he would dare or was into that, and he replied that he would if I wanted it. He lowered my knickers around my thighs and reached around to slowly fondle my now rock hard cock, and gently eased his cock into my ass. It felt really thick and hard and filled me well. Slwoly, he started to speed up and pump me hard until he came and I felt his cock pulsing as he came. Since that time we have fucked in the outdoors many times. Sometimes I wear panties and holdup stockings for him, as he enjoys fondling me through them. Just wish there were a few doggers around to see what we got up to!!
