*****
Joan was feeling that she had settled into effective management of both the home and the family for which her mother had left her, the youngest of four, responsible for running. For the work this required of her, Joan was rewarded by also inheriting her mother's disciplinary authority over her siblings, their partners residing in the house with them, and the staff retained to serve the family.
Her mother, Jennifer, had been tyrannical and frequently spanked and caned those she felt had violated her rules, often in front of the rest of the family. Joan had ended the weekly meetings, which mostly had served as occasions for discipline to be awarded and carried out. When Joan believed someone had overstepped her bounds, however, she had shown no hesitation in awarding what she deemed to be appropriate punishment.
This was a heavy responsibility cast on Joan, a petite, attractive woman of 24. Her siblings, Jill, 32; Ken, 30, and Emily, 27, did not resent Joan's being put in charge because they felt they would not enjoy being the arbiter and disciplinarian of the house. Ken was affianced to Andrea, who was 28, and Emily had been living in her rooms with Grant, was her age. Jill at present had no partner or live-in, having dispatched both a man and woman who had been with her when she came upon them making love in her absence.
One of Jennifer's means of control was to require the siblings to enter personal information on a large chart in the common room that was only open to the four and their guests. On this calendar-oriented board, Jill, Emily, Joan, and Andrea entered the dates they were on their periods each month. An entry was required for each day, along with a description of the light or heavy nature of their flow. The men were spared this but were included in a companion chart that each of the siblings and their partners would enter each time they had a bowel movement.
Jennifer felt that these charts provided her with intimate information and showed her control over the group. Since the family had long engaged in incestuous relations, this also let each person know who might be available for period sex, since all enjoyed this time of the month rather than avoiding any of the women who happened to be menstruating. All did feel that the most humiliating aspect of the charts was having to describe one's bowel movement. Jennifer had made a point of mandating complete descriptions and would punish anyone who limited their entries.
Everyone had accustomed themselves to these somewhat humiliating interferences into their privacy and were not surprised when Joan had continued to require appropriate entries to be made. She added a column for the women to indicate exactly what kind of menstrual protection they were using and made everyone make a special note if they had not moved their bowels in two days.
Given the openness of the house in terms of discussion of intimate subjects, the women found it amusing to compare their feminine hygiene practices. It was probably the societal taboo against even discussing this subject that was a turn-on for Jill, Emily, Andrea, and Joan. Andrea, who was not yet married to Ken but had been accepted by her future sisters-in-law, had found accommodating herself to this unusual situation somewhat challenging but soon enjoyed the give-and-take around the subject.
The others, in fact, had been quite fascinated upon learning that she was using a menstrual cup. Jill and Joan were tampon wearers and Emily continued to prefer pads. Emily remained a subject of more teasing about her continuing to be what her sisters called a diaper-user. One day Jill asked Andrea if she would mind showing them how she inserted and removed her menstrual cup. Andrea was initially embarrassed by the request, and this was confirmed by her blushing face. But she grinned and said sure, they could watch her stick it up her cunt.
Since no one had many inhibitions in light of their frequent pairings for sex, Andrea did respond that she would invite Ken to be present and Jill showed no resistance to that. One afternoon after everyone had returned from their work, the sisters gathered in Ken and Andrea's rooms after seeing that Andrea had entered the onset of her period on the chart. Andrea had decided to play this for some laughs as well as formal instruction, so she donned a white gown and plain white panties underneath it.
Ken told her that he really wasn't that interested in seeing how a menstrual cup worked, especially since he thought his presence would inhibit the others. Andrea said he should be interested but decided to let him off this time.
Andrea lay back on their bed and everyone gathered on both sides. She lifted the gown and then lowered her panties to disclose her very attractive shaved mons and vulva.
"Normally, I perform this function sitting on the toilet as I know some of you do when you insert or remove your tampons," she declared. Then she spread her legs, held her labia apart, and reached into her vagina with her fingers and deftly extracted the cup that had been covering her cervix. She managed to slowly grasp it by the stem and pull it gently down and out of her vagina without spilling the dark-red menstrual flow that was in the cup.
She then sat up holding it and told them she would take it to their bathroom to empty the cup into the sink and wash it for re-insertion. When she had done this, she returned, and this time sat on the side of the bed.
"Inserting the cup is the tricky part," Andrea said calmly, "but it gets to be a routine like anything else, well, not anything, but for women, at least, putting a tampon in."
Then she took the cup and held it by her thumb and forefinger, then slipped it past her labia which she was holding open with her other hand. They watched as her fingers seemed to slide the cup into her vagina and push it until Andrea said she felt it settle onto the protruding cervix deep inside her.
Jill told Andrea that she was a marvel because Jill found it challenging even to properly position a super plus tampon.
"Speaking of penetrating," Joan added in with a note that elicited chuckles, "does Ken ever reach your cervix when you are fucking, if you will pardon the indelicacy of my words, Andy?"
"You all know that he's long enough to do that but that he also knows not to push it in this instance because no woman enjoys feeling a cock smacking her cervix," Andrea responded coolly.
Emily tended to go into this subject more than the others would feel comfortable doing, so she proceeded to ask Andrea if it was more difficult to insert or remove the cup when she needed to have a bowel movement.
This actually did make the seemingly imperturbable Andrea blush, but she recovered enough to say that needing to have a bowel movement did press on her vagina when she passed the movement, so she would not go about putting in or taking out the cup when she was about to "make doodoo" as she smilingly added.
"And in response to the question no one has asked," Andrea concluded, "I do take the cup out before having sex just like you would remove a tampon."
