A good neighbor

possibility. When they were facing me again, Gail asked 'Wouldn't that mean we were, like, lesbians?', followed by Emma's plaintive 'What happens if someone finds out?'

I snorted before answering 'You can't know if you're lesbians until you know whether or not you like to have sex with a guy; lesbians only want to have sex with other girls. If you like to do stuff with girls AND guys, then you're what they call 'bi-sexual', which just means that you like both.

There isn't anything wrong with being bi-sexual, or even a lesbian; it's just different, is all. If it turns out you like it, and you can make each other feel good, does it really matter? And who's going to find out, and how? If you're doing things with each other, I don't think you're going to say anything, and you know I'm sure not going to… so who's going to know, except you?'

They looked at each other again for several seconds before turning back to me and Emma saying

'I… I guess we could, um, try.' A moment later, Gail asked 'Gary? Could you… could you maybe be with us at first? Kind of help us get started?', followed by Emma nodding her agreement.

I really hadn't expected to be asked to help them find out what it was like to be with another girl; but once the question had been asked, the idea of watching and being involved as they got intimate with each other did wonders for my libido. My answer was delayed only by the necessity of calming myself before I told them 'Sure, I can do that.'

After they'd shared another look, both of them got up to stand next to the couch; I followed their example, and each of them took one of my hands before leading the way back to my bedroom.

When all three of us were naked and on the bed, we sat there in a rough triangle for a few moments before I leaned over to give Gail a soft kiss on the lips — then did the same for Emma.

Looking at each of them in turn, I told them 'I can understand that this maybe feels kind of weird, but it shouldn't. Yeah, both of you are girls — but that only means that both of you know and understand what it feels like for the other one. You shouldn't worry about being sisters, either, since that just lets you know that you love and trust each other.'

They considered that for a moment, then smiled in acceptance of what I'd said. Next, I told them

'Both of you have told me that you love me — but I'll bet that each of you loves your sister even more. How about if you try something simple, and easy first, like kissing your sister? I don't mean like you usually do; what I'd like you to try to do is use your lips to tell her how much you love her. No touching or anything, just kissing. Can you do that?'

It took them a moment to start, but once they'd brought their lips together, I could tell as each of them tried to do what I asked. Their first kiss was brief and tentative, but after they'd looked at each other, they tried it again; only a few seconds passed before it was clear to me that they had managed to connect. Their second kiss lasted appreciably longer, and they were seeing each other in a new light when they finally broke apart. They were still looking at each other when I suggested 'Maybe you should look at each other. I'm sure you've seen each other naked before, but have you ever really looked? Take some time and really see your sister — not just what her face looks like, but the rest of her, too. Really look at what her skin is like, and the size and shape of her breasts, and what her nipples look like, and how her body is different than yours, and how it's the same.'

From the side, I watched them as the really looked at each other — probably for the first time in their lives. Even as they were checking each other out, I was taking the opportunity to do the same with both of them; their different bodies, breasts, profiles, and all the rest. As I watched, both pairs of nipples began to erect as each of them started to recognize how pretty and sexy the other was. After several minutes had passed, I could see that they were looking into each others eyes; quietly, so that I didn't break the bond between them, I told them 'Look at her. She's your sister, and you know you love her, and think she's pretty. Don't you think she'd like it if you did things that would make her feel good? Go ahead and touch her — use your hands and fingers to tell her how pretty you think she is…'

With that, it took only a moment for Emma to raise her hand; she'd barely lifted it off the bed before Gail was doing the same thing. I watched as both of them slowly reached out to softly touch one of her sisters breasts — and both sets of nipples erect even more at the contact. The two of them spent several minutes touching each other; mostly on the others breasts, but also caressing shoulders, and necks, and waists, and hips. I didn't have to say anything for Gail to start to lean toward her sister with the obvious intent of kissing her again; Emma saw what Gail was doing, and didn't hesitate to meet the younger girl halfway. It was a matter of just a couple of seconds before they were kissing with much more affection and intimacy than they had the first time. As their lips stayed together, each began touching the other more, and longer, and more passionately. Emma was the first to cup her sister's breast and begin gently squeezing and caressing it, but Gail readily followed the older girl's example.

I watched, entranced and incredibly aroused, as the two of them gradually increased the intimacy of their contact; Gail let one hand slowly drift down and come to rest on the inside of one of Emma's thighs; it took only a second for Emma to open herself in invitation for the younger girl to explore even farther — which she did, after parting her own legs.

Over the next several minutes, I continued to witness the steadily growing love and desire between them as they took turns nursing at each others breasts, kissing each other on the lips and shoulders, and tenderly caressing each others bodies and more intimate areas. It was Emma that eased her sister onto her back, and spent a few minutes orally tending Gail's bust before starting to slowly kiss her way down the younger girl's body. I remained still and quiet, and both of them completely forgot about me as Emma's lips eventually drifted into the soft down of Gail's sparse bush. A minute or so later, Emma gradually eased her head between her sister's thighs; a few moments went by before Emma raised her head to tell Gail 'Gary was right — we are pretty here, too!'

Hearing that, I was half-afraid they'd remember where they were, and that I was there with them

— but they were apparently so focused on what they were doing with each other that it never seemed to cross their minds. Instead, Emma simply lowered her head; I watched as she took a breath through her nose, savoring the unique aroma of her sister, before extending her tongue and drawing the tip of it across Gail's visibly wet opening. The expression on her face as she got her first taste of another woman's essence was one of surprised pleasure, followed by a look of anticipation as she moved to do it again. In less than a minute, she was eagerly applying herself toward stimulating Gail into producing even more as her sister began to moan in response to what Emma was doing.

Despite the press of work and the deadlines facing me, I simply had to continue to sit there as Emma slowly, but steadily, moved her younger sister closer and closer to an orgasm. I'd learned the little signs that told me Gail was close to her release when Emma changed what she was doing (I couldn't see what it was, dammit!); less than a minute later, Gail froze in place with the start of her climax. I saw Emma's head move slightly, and figured she was doing what I would have — lapping up the surplus fluids that escaped Gail whenever she had an orgasm.

As Gail's orgasm tapered off, Emma raised her head from between her sister's thighs; her face was glistening from lips to chin, telling me that she'd been doing what I'd thought she had.

Carefully, Emma moved to lay next to Gail again, facing her so that the two of them could look at each other as Gail got her breath and senses back. When she could, Gail tilted her head forward enough for them to exchange several brief, gentle kisses. Only when they were just looking at each other again did Emma remember that I was there with them. She turned her head to look at me, followed by Gail doing the same. Both of them blushed slightly, but simply waited to see what my response would be.

Smiling, I looked from Emma to Gail and back again before telling them 'There, now, that wasn't so bad, was it?'

It was Gail that told me 'Not even! It felt good!'

Emma told me 'I was kinda nervous about kissing that first time, but after that it was easy. It felt a little funny to be touching each other at first — but it felt nice, too. After we started kissing and touching, I just kinda forgot about anything else…'

'You think you'll be okay with helping each other, now?', I asked.

They looked at each other and grinned before Gail told me 'Yeah, we'll be okay. But we still want to be with you when we can!', accompanied by Emma's nod of confirmation.

'I want that, too… when I can. But right now, I have to get back to work. You can stay here as long as you
