For the rest of the evening, I couldn't figure out what was going on with them. But by the time I was ready to go to bed, I'd decided that I was not only willing to accept whatever they offered, but even see how far I could get them to go with it.
Both girls turned up fully dressed for breakfast the next morning, and after they'd left for school, I went back to my place to work. Andrea got home late that afternoon, and came over to collect the girls, who had come to my house after school. I didn't have any trouble convincing her that they hadn't been any trouble at all, which pleased all three of them. Andrea told me that she'd passed the test, and would have her certification within a week — and then hugged me and kissed me on the cheek, thanking me for helping her get it by watching out for her daughters.
While she wasn't movie star material, Andrea was still attractive and had a nice shape, so I was glad to be able to hug her back. When she'd released me, she told me that I was invited over the following Sunday for a special meal to thank me. I told her it wasn't necessary, but gave in when she insisted.
Emma and Gail both came over to use the pool on Saturday, and after they'd been in the back yard for a little while, I went out to check on them. Both told me how happy their mom was to have been able to take the test, and that her boss had promised her a promotion by the end of the month.
As we were chatting, I make a point of letting both of them see me looking them over; after a bit, I casually commented "After I stayed with you the other night, and the way you came in to kiss me good night, I thought you'd be letting me look at you more."
Gail asked what I meant, and I told her "After you let me see you like that once, it isn't like you've got to hide yourselves, or anything. And I told you that I thought you were both lovely, so you don't have to worry that I won't like how you look, either. I guess you're not as grown up as I thought you were, after that."
Both of them looked at me for a few seconds before Emma asked "You… you really liked how we looked? You didn't think our boobs are too small, or anything?"
"Of course I liked how you looked — didn't I tell you that? And no, I don't think your boobs are too small. As a matter of fact, I think they're very nice — both of you."
Gail hesitantly told me "We weren't sure you really meant it when you said we were lovely; we thought maybe you were just saying that to make us feel good, or so we'd go away."
When she was done, Emma asked "It's really okay with you if we show you our boobs again?"
I answered them by saying "I think you know that I have never lied to you" — both nodded, because I hadn't — "so why would I say something like that if I didn't mean it? It's certainly okay with me if you want to show me your boobs, if that's what you want to do. I think both of you are very pretty, and your breasts are nice to look at. Even if you wanted to just go around topless over here, it would be okay with me. But it's up to you whether you think you're mature enough to do that or not, of course." With the tall privacy fence around the back yard, nobody was going to be able to see the relatively secluded corner where the pool was.
As I figured, the suggestion that only mature people would be agreeable to going topless hit them in a sensitive spot; one of the things I'd learned over the years was that pubescent girls almost always want to believe they're more mature and adult than they really are.
But I changed the subject to something else, and we chatted for another few minutes; when their was a lull in the conversation, Emma looked at me, then her sister, before reaching back and unfastening the top of her bikini — then removed it and set it aside. A few moments later, Gail did the same thing, leaving me sitting there with clear views of two pairs of firm young mammaries. I didn't make any big deal out of what they'd done, however. I just smiled at both of them, then went back to talking to them as though half-naked teenyboppers was something I saw every day. After a bit, both of them stopped looking quite as nervous; by the time I had to go back to work, they were as calm and relaxed as they could be. Inside my house, I looked out at them and watched as they decided to go for another dip in the pool — without bothering to put their tops back on.
I checked on them a few more times while they were at my place, and they didn't put the tops of their suits back on until right before they went home.
The next time Gail and Emma came over, they were on their own in the back yard; I was busy with a tricky bit of code I was working on. When they first showed up, I noticed that both kept their bikini tops on; but when I looked at them a little later, both had opted to shed them, to my pleasure.
When I went out to check on them, both looked a trifle nervous at first, but when I didn't stare or say anything, they settled down again quickly enough.
After that, any time they came over, one of the first things they'd do would be rid themselves of the encumbrance of the top half of their suits. Emma finally told me that they'd decided that they liked the feeling of swimming and laying in the sun topless, and that my casual acceptance of their semi-nudity made them feel a lot better about it. Even so, both kept the cloth handy on the off chance that their mother came over — neither thought that she'd understand. The gate they and Andrea used had a noisy spring on it, so the sound of the gate opening would give them time to grab their tops and jump in the pool where they'd be out of sight while they got them back on; something that proved necessary a couple of times. Both times that happened, they had an attack of nerves afterwards. The first time, they kept their tops on the rest of the time they were swimming; after the second, Emma, then Gail, opted to go topless again after a few minutes.
Once they'd gotten comfortable about being topless around me, I finally let them talk me into joining them for a swim again. It wasn't difficult to get them into a dunking contest again, and even though I was careful not to actually put my hands on their tits, I still got enough of a feel of them on my arms and chest and back to appreciate how firm they were. Neither girl seemed to have any problems or concerns about the contact while we were playing, or afterwards.
Andrea got the promised promotion, and the pay raise that went with it.
She also discovered that she'd also acquired some additional duties — duties that made it necessary for her to work later than she liked, and more often than she wanted to. But the additional income was too good to pass up, so she accepted the necessity of the added hours.
Those additional later hours meant that she wasn't home as much, too. Rather than leave the girls on their own all the time, she asked if it would be okay for them to come over to my place sometimes, while they did their homework, or studied. With Emma and Gail both understanding that when I was working, I couldn't give them much of my attention, I didn't have any problem with that. Still, Andrea and I both made sure that the girls knew that it wasn't to be an every day kind of thing, and that the business of not bothering me while I was working still applied.
After a few weeks, it became clear that the two of them were coming over maybe a bit over half the times Andrea had to work late. I wasn't obliged to be working all that time, so there were chances for me to sit around with them — helping with their homework if they needed it, just generally keeping them company, or whatever.
I used those occasions to begin getting them comfortable talking to me about things; more than just the day-to-day kinds of stuff that usually occupied our conversations. Rather, I was interested in moving things to the point that either of them would be willing to talk to me about more and more personal and intimate topics. I started out by just making small comments about minor things in passing; then I began to include more and more subjects, again keeping my remarks short and casual. Once they were comfortable with that, I gradually drew them into the subjects; by the time I was done, neither of them was the slightest bit reluctant to talk to me about virtually anything — even to letting me know when one of them wasn't going to swim because she was having her period.
