That was all she needed to hear on the subject of the girls, and a couple of minutes passed before she started telling me how things were going at work for her. In return, I told her how I was doing, and the two of us sat there and chatted for over an hour. When I asked, she said that she still had to go in to work the next day, so I excused myself and went home after we'd agreed to get together the next evening to work out how to deal with her immediate problem with the girls.
As I went to bed, I thought about all that had been going on the last few months — not just between me and the girls, but what I'd seen and heard of Andrea, her job, and all of them.
Neither Andrea or I expected to find a quick or easy solution for how she could talk to Emma and Gail about what she'd seen — and we didn't. Andrea easily admitted that the single biggest problem was her own upbringing and attitudes; recognizing the problem wasn't the same as dealing with it, however. Still, with no small effort and plenty of patience and commitment, we finally managed to get her to the point that she was able to accept that while she didn't like what the girls had been (and almost certainly were) doing, she was able to at least consider it without going off the deep end. With some more work, and careful preparation beforehand, she was finally ready to sit down with the two of them and talk to them about it.
Naturally, both of them came over to tell me about it afterwards — something Andrea had told me she expected, and was fine with. Both girls were embarrassed that their mother had seen them, and nearly dumbfounded at her (apparent) equanimity. As I'd agreed with Andrea, I told them that while there wasn't anything to be embarrassed about, they should still take care not to do anything when or where their mother might find them — that even though she hadn't told them that it was bad, or that they had to stop, that didn't mean that she actually approved of it. I went on to suggest that unless they wanted her to say anything like that, they needed to be a lot more careful; then went on to tell them that they could come over to my place to be with each other, if they wanted to. Both were delighted, and didn't have much (any) trouble talking me into letting them show their appreciation with a repeat of what we'd all done after their first afternoon together.
Slowly, and carefully, Andrea let them know over the course of the next couple of weeks that she was okay with the idea of them coming over to my place not only more often, but for longer periods of time. After that, she got them clued them in that she wasn't going to be terribly inquisitive about why they came over, or what happened.
When Andrea got an invitation to attend a special three-day, two-night seminar, Gail and Emma were overjoyed when she agreed that they could just stay with me while she was gone, rather than having me running back and forth between the two houses. To my relief, the girls didn't insist on any kind of sex marathon. We certainly had our share of fun with each other, and both of them stayed in my bed at night, but that was about the extent of it. When Andrea got back, both of them were considerably happier and more chipper than they'd been when she left; Andrea mentioned it only in passing a couple of days later.
With Emma and Gail coming over more often, together and individually, I had even more opportunities to slowly increase the level of intimacy I had with them. From using only their hands and mouths on my cock, it didn't take long for them to begin finding pleasure at having it between their legs — and then actually having it rubbing against the outsides of their vaginas.
Along with that, it was easy enough to get them to accept the idea of carefully using their fingers to touch each others opening, and even start pressing against it. When they inquired about their virginity, I dug out a hand mirror I had, and I sat down with the two of them and helped them open themselves and each other enough for them to see the barrier that defined them as virgins.
Neither hymen appeared to be much more than a thin ring to me, and didn't think that either one would be much of a problem when the time came. Both of them wondered aloud what all the fuss was about; I took the opportunity to explain a bit of history to them, and how the presence of a maidenhead was considered a sign of purity to the husband — who was considered to be all but her owner. Both were more than a little indignant at that idea, and expressed the attitude that nobody was going to own them… something that was music to my ears.
Each knowing the particulars of her situation, they were willing to begin careful experimentation with the idea of penetration. Their first efforts were extremely brief and tentative, but they slowly got more used to the idea, and comfortable with the act. To my infinite delight, I was called on to assist several times, and privy to witnessing many more. I was there to watch when Gail succeeded in getting nearly her entire finger inside her older sister, and the near-ecstasy on Emma's face that resulted. That only prompted Gail to greater willingness for Emma to do the same to her, with almost identical results. Both girls took great care not to actually break their (or each others) hymen — but they weren't above stretching the hell out of them.
As the weeks passed, two different aspects of their sexuality became closer and closer for both girls — their comfort with having something inside themselves, and their willingness to have my erect cock directly stimulating their genitals. Not once did I suggest to either of them that anything should happen between us, nor did I ever attempt anything like coitus with them; it was invariably at their suggestion that they would rub themselves against my erection, or that I would gently ease the end of my finger through the portal of their womanhood. I was also taking every opportunity to increase and prolong their arousal and pleasure; rather than just help them have increasingly stronger orgasms, I would also take a little more time in how long it took for those orgasms to happen. In return, they learned to take their time about bringing me, and each other, to climax, as well.
There was going to be a movie on cable TV that all of us wanted to see, so I invited the three of them over to watch it on my big-screen TV, instead of the smaller one that they'd had to settle for after the divorce. Andrea also let me spring for pizza with only a token amount of protest, which delighted the girls.
It wasn't too late when the movie finally ended, and Emma and Gail sat and listened when Andrea and I started talking. She said something about Emma's upcoming fifteenth birthday (just a couple of weeks distant), and I turned to ask Emma what she wanted. I was a little surprised when she told me "There's only one thing I want, but it's something Mom would have to help me with."
When I looked at Andrea, I could see that she was even more surprised than I was before she asked "Then what do you want, Em?"
Looking straight at her mother, Emma calmly dropped a bombshell into the middle of my living room by answering "All I want for my birthday is for you to make an appointmet for me so I can start using birth control."
Andrea immediately turned to look at me — and must have seen that I didn't have any more idea of where Emma had come up with it than she did. Turning back to Emma, Andrea asked "Do you need birth control?", more than a little suspiciously.
Emma remained calm, and simply answered "No, not yet. But I want to be ready, for when I do need it."
"Don't you think maybe you're a little young?", Andrea wanted to know.
" I don't think I am. Mom, I'm not having sex yet — I'll go to the doctor any time you want, and he can tell you that I'm still a virgin. I'm asking you to let me start using birth control so that I can make sure that there aren't going to be any problems or anything before I stop being a virgin.
