Hillary and Tiffany Duncan, 18 and 19 years old respectively, were aware their mother, who had been divorced for over ten years, had overnight guests in her bed from time to time. They also knew the guests were sometimes men and sometimes women. They saw nothing at all wrong with what Mom was doing; she was only forty years old and certainly had needs to be taken care of. She also treated her daughters as the adults they were, providing them with birth control pills and raising no objection when they had young men as overnight guests. She did advise them to be careful and to insist the men use condoms, but she otherwise mostly stayed out of their sex lives.
Hillary was a senior in high school and Tiffany was in her first year in a local community college, satisfying some elective requirements before beginning to attend the state university in the neighboring city. During Spring Break, they were both home and bored, and discussing the probable sex life of relatives and mutual acquaintances, including their mother. Although both young women regularly enjoyed sexual activities with men or boys, neither had ever had any woman on woman action, and they were curious about exactly what it would involve.
"What do you suppose Mom does with the women she gets it on with?" Hillary asked her older sister. Although young, she was enough of a woman of the world to have some ideas about lesbians and bisexual women and what they did with each other in bed, but she wanted to hear the salacious details.
"I suppose they eat each other's pussies and sometimes they fuck each other with plastic cocks."
"Did you ever use a cock like that? It doesn't sound like as much fun as the real thing."
"They're called dildos. I've seen them advertised online, but I've never seen an actual one."
"Do you think mom has one?"
The teenagers looked at each other and, almost simultaneously, both sisters said "Let's go find out!" They arose from the chair and sofa on which they had been lounging and hurried into their mother's bedroom to begin their search.
The first possibilities were the simplest and most obvious - under the pillows and under the mattress, but they had no luck in either place. Their mother's alarm clock sat on a bedside table that also had a small drawer, but they found nothing there either. That left the dresser and the armoire with its three large drawers.
Hillary began carefully rummaging through the top drawer in the latter, looking under the family's winter clothing, but finding nothing of interest. Tiffany had better luck, reasoning something intimate such as the thing they were seeking would be in an intimate place, so she began with the small drawer where their mother's bras were kept. Finding nothing among those garments, she opened Mom's panty drawer, and there she hit pay dirt. When she felt under the silky garments, her fingers met a hard cylindrical object and, from her personal experience, she recognized the shape of a cock. Carefully moving the panties aside disclosed a large white object.
"Here it is," she told Hillary.
"Well, bring it out, and let's have a look."
Being careful to avoid any undue disturbance, because she wanted to replace the exotic device exactly where she found it, Tiffany removed the object from the panty drawer. When she held it up, she was surprised to see the attached straps, and showed it to her sister.
"Big, isn't it," Hillary remarked. "But what are the straps for?"
She took the strange object and held it up by the larger of the two elastic belts. The toy consisted of a black triangular piece of leather or something similar, with a thick, seven-inch long cock protruding from the center and a wide, black strap connected to two corners of the triangle. A narrower strap of the same color was fastened to the third angle, and the other end of the smaller band terminated in a loop with the wider strap passing through it. When she held it in front of herself with either of her hands gripping the wider strap and pulled it taut, she realized how the dildo would be worn and used by a woman.
"Look," Hillary explained. "Mom or the other woman sticks her legs through these places and buckles the strap around her hips so the cock is where a real one would be on a man, and she uses it to fuck her partner."
As both young women gazed at the big plastic cylinder fastened to the strapon, they began to think about something neither of them had done lately. The protruding cock was bigger than they were used to, but otherwise looked just like something they enjoyed, but neither had felt for over a week. Once again, they had almost identical thoughts, but Tiffany spoke first.
"Do you want to try it out?"
"Do you think we should?"
"Why not? We can clean it off when we're done with it and put it back, and Mom will never know."
They stood for a few seconds, turning the idea over in their respective minds, before the older of the two spoke first again. "I get to fuck you first."
"How come?"
"Because it was my idea and I'm older."
