She pulled out a small package about one and a half inches square. I could see the outline of a ring inside the package."This is one rubber. It's also... called a prophylactic or a condom but we'll just use the common word. It is designed for one use and one use only. It should be thrown away so that no one can get to it when you are finished. The safest thing to do with it it flush it down a toilet. Since you are the male and are carrying the sperm that can make a woman pregnant, you are. "Yep, they're definitely bloody sexy" I agreed as I resignedly reached yet again for my wallet, "But who made the rule that the less material there is in a garment, the more expensive it should be?" Oh stop whinging" she laughed as I handed over the entire years defence budget for a medium sized banana republic to the grinning old hag behind the counter and wondered briefly if she actually modelled them!"You know they get transparent when they're wet don't you?" she hooked an arm through mine. When we got home and in the house, mom went to her bedroom and got undressed, then came to my bedroom, where I had her new blue dress and blue thong pantys and blue bra, both the sheer one's, laid out on my bed for her to put on, for when dad got home.Mom helped me get undressed while I was going through the video of dad's office, starting where I had left off to go out to eat, then as it played through, mom gave me a blowjob.Mom licked my balls and my dick all the way to the tip before taking. She could feel every flick with his tongue and it made her beg for more. She pointed the way to the bedroom and he agreed, so she lead him up the stairs to the room on the right. He pushed her onto the bed and ripped off her small pink shorts. He knelt down and put his head between her legs, licking her clit and flicking it, he used his mouth and his tongue well, pleasuring her. His hands pushed her legs further apart so he could reach in as far as possible. She screamed out with pure happiness.
