We would spend a lot of time outdoors in the backyard, drinking beer and talking shop. Whenever they came over, they were used to just coming in and...not knocking. We were like a big, happy family at work and we got along great.My wife and I had gotten married in May, 1975. It wasn't a large wedding, but we had our families there. My best friend Willie was my best man, and my wife's best friend her maid of honor. We had fooled around some before marriage, and I knew she knew a little about. The thought of fucking my dirty little sister makes me so horny. What would mom or dad think, if they came out of their room right now. Their son sitting at the computer with his pants at his ankles, jerking off, while their sweet little princess fingers herself watching him.You let out a soft moan. Your eyes open wide, your left hand shoots up to cover your mouth. But I see your right hand still working your clit and you don’t take your eyes off me. Off my erect cock, my hand moving up and. Don’t stop. He cummed inside me..As I had my second orgasm.We both are exhausted with the fuck. I moved with my cum dripping pussy and licked his cock to get some bonus cum. I sucked his cock again… After some sucking he cummed for the fourth time in a day.. He cummed all over my face and body.. I licked his cock clean !He already slept due to the exhausting cum drops. I licked all the cum which fell on my boobs and face with the help of my fingers. Yummy!!! I bathed in his bathroom and I wore. We cleared away, taking the blower back to the workshop and towing the bowser over to the big compost heap on the far side of the vegetable garden to empty it before washing out the interior. Then we went back to inspect our work. The wooden covers we'd put over the broad, shallow troughs Robbie had cast out of dark grey concrete were removed by leaning over the walls of each sty. The covers had kept out nearly all of the blowing chaff and slurry, and what remained wouldn't matter; our guests.
