"FUCKING!" I exclaimed loudly. "I don't think so, Emma. That'd be going too far."
"Now just wait a second, Uncle Jeff," my young niece said insistently. "Do you agree that fucking would be the surest test to see if we're lesbians?"
"Well, yes, you are right about that. But it would just be wrong."
"Why?"
"For one thing, I'm your uncle. And for another thing, I'm a lot older than you are."
"But I don't care that you're my uncle. For me, that would make it better. I trust you and know you care about me. You do care about me, don't you Uncle Jeff?" she said as she gave me those big doe-like eyes.
"Of course I care about you, Emma. But I'm 32. You should find this out with boys your own age."
"But the boys our own age are all idiots. They're clumsy and awkward and just care about themselves. It would be so much better to learn from somebody older who knows how to treat girls like us. Don't you think so, Sharon?" Good girl, get Sharon included.
"Well...I...I..." Sharon stammered as she sat up next to me, a little more alert now after Emma had broached the subject of fucking.
"Don't you think it would be better to try it with Uncle Jeff than any of those yucky boys from school?" Emma repeated her thought to her friend.
"Well, uh...yeah...I guess so," Sharon said with a note of uncertainty in her voice.
"See, Uncle Jeff. It's not just me that thinks it's a good idea. Sharon thinks so too."
"What do you think about this idea, Sharon," I said as I turned towards her.
"Well...I...I don't know," she said nervously. "I've loved everything we've done so far tonight." She paused as she thought about what she wanted to say next. "I...I'm just not sure if I'm ready to try that." She looked at me with a look of confusion and apprehension on her face.
"That's okay, Sharon," I said as I reached over and stroked her cheek tenderly. "Nobody's gonna make you do anything you don't want to do. I promise you that." This brought a smile to her face and I could see a feeling of calmness roll over her pretty features.
"Well, what about me, Uncle Jeff?" Emma asked with a pleading tone to her voice. "I'd like to try. Will you...will you do it for me please?"
"I don't know, Emma," I said slowly so they could definitely tell that I was wavering on my earlier decision not to. "I'm just not sure it's a good idea."
"Please Uncle Jeff? Is it because you don't think I'm pretty enough?" She asked as she gave me a big pout.
"No, I think you're very pretty, Emma." I paused as I looked at each of them in turn. "I think you're both beautiful young girls. I really mean that."
"Haven't you ever wondered what it would feel like to fuck a girl our age?" Emma said as she leaned back down and took a long loving swipe with her tongue all along the full length of my cock. Oh fuck, her doing that right after what she had just asked me sent a surging jolt right through me.
"Well...I..."
"I bet you have," Emma said as she slipped her lips over the broad crimson head of my cock and bobbed her head a couple of times. She slowly lifted her mouth back off and looking up at me teasingly as she licked that beautiful soft tongue of hers all around the spongy membranes of my cockhead. She had that smoldering lustful look in her eyes that I was in love with already.
"I bet you've looked at girls like us in our little school uniforms and thought about what it would feel like to get your hands on our hot young bodies." Holy fuck! We hadn't talked about this at all when we were getting our plan together. She was coming up with this on her own, and she had me totally at her mercy...and she knew it!
"Ummm...I..." She had me totally at a loss for words now.
"Mmmmmm, I can tell by the way your cock just throbbed in my hand that I'm right. C'mere Sharon, feel how hard it is." Sharon seemed as enthralled by what Emma was saying as I was and she quickly scrambled to her knees and moved down until she was right beside Emma. Her hand reached out and I felt the warm soft grasp as she wrapped her hand around my rigid cock below Emma's.
"Oh God! It's so big and hard again already!" she exclaimed as she leaned in close to the throbbing knob. "Look Emma, there's some of that precum already." Sharon flicked out her tongue and gathered up the silky drop that had started to ooze forth from the long gaping piss-slit. As she drew her mouth away and licked her lips, Emma moved her hand up and down my stiff shaft coaxing more precum to the surface. She leaned closer until the broad enflamed crown was right in front of her face.
