Though my expression never changed, and I stayed quiet and impassive, I was considerably amused when the first thing each of them did was to run her fingertips through my pubic hair, above my penis. They must have spent nearly two full minutes just marvelling at how different it was from their own growths before Karen tentatively took my flaccid penis between two of her fingers and lifted it up from where it was laying on top of my scrotum.
When I didn't have any visible reaction, Wendy and Donna then began their own investigations.
After that, the next few minutes went by with all three of them fascinated by the particulars they found. With all three of them dressed, and me again feeling like a particularly interesting biology specimen, having their soft hands on my equipment wasn't exactly stimulating for me. I knew that Phase One of the program was over when Wendy closed the book she'd brought along, then moved up to give me a kiss on the cheek (and get one back, along with a pat on her butt) before she told me "Thanks, Uncle Ted.", and smiling when I answered "You're welcome, honey."
After Wendy had been gone for several seconds, Donna and Karen shared a brief look before both of them got off my bed and began undressing. Once naked, they got themselves situated next to me again, one on each side. Apologetically, Karen told me "I… I want to see what happens when you get excited, but I don't think I'm ready to, um, do anything with you yet."
I quickly assured her "That's fine, sweetheart. I don't want you to ever do anything you're not ready for, okay? I will never, ever be mad or upset if you want to wait and make sure before you do something."
I could see that my words had the desired effect when she smiled, and nodded her understanding.
Donna then asked me "What should I do, Uncle Ted? To get you excited?"
I looked at her, and calmly answered "What you should do is only what you want to. What you can do is try doing to me what I do to you."
"But you're a guy, and you're not the same as me!"
"No, but a lot of what works on girls will work on guys, too. Sure, all our parts are on the outside, but that really just means that it's easier for someone to get us excited. Instead of a small clitoris like you have, I've got the head of my penis, which is pretty easy to find" — that drew a laugh from both of them — "and has the same effect on me. Instead of the pretty flower petals that you have" — both gave me pleased smiles at my description — "there's the shaft of my penis." Then, sounding like a TV ad announcer, I added "But wait! There's more!", making them laugh again before I finished "There's also my testicles, inside my scrotum. They aren't as sensitive, but if you touch them and gently play with them, that helps, too. And pretty much every guy is going to be easier to get excited if he can touch you, too."
Smiling, both of them scooted themselves close enough that I could reach them; then Donna reached out and took my cock in her hand as I put a hand on each of their cute little asses. Donna seemed uncertain what to do once she had hold of me, so I started caressing her smooth, firm ass cheek; a second later, she began stroking me.
It took a couple of minutes before she began to get the kind of reaction she wanted; once she did, though, it didn't take her long to increase and expand her efforts. She wasn't hurting me, so I was perfectly willing to let her learn what to do, and how, on her own. Besides, it gave me time to enjoy playing with both of their lovely tushes. Once I was almost fully erect, I heard Karen's incredulous voice say "It… it's so big! I didn't know they could get like that!"
Calmly, I told them "Believe it or not, that's about the normal size for men. I'm about as average as I can be — some are smaller than me, and some are bigger. It's a lot like girls and how big their breasts are — I'll bet you two aren't much different than most of the girls your ages, but that there are some that are really small, and some that are really large; but most of you are pretty close to the same."
I saw as both of them silently nodded in agreement as Donna continued her efforts. A little later, Donna managed to convince her sister to try it for a bit; the first thing Karen said after wrapping her hand around my turgid manhood was "It feels so warm! And it's so soft on the outside, but still so hard…"
Once she'd given me a few slow strokes, Karen wasn't reluctant to continue for a little longer -
but didn't hesitate to release me when Donna indicated she wanted to continue.
A few more minutes, and I was fully erect… and starting to enjoy Donna's efforts. Not sure what they had in mind, I figured I'd better give them some idea of what they could do by telling them
"Donna, what you're doing feels good for me, and both of you know what it looks like when a guy gets excited. Now, there are a couple of ways we can do this, depending on what you want to happen. Karen, it's up to you whether or not you want to see what happens when a guy has a climax. Donna, if you want us to, you can help me have a climax before we do the other things you wanted to find out about. If you do, then it'll take a little time before I can get excited again
— but, I can do the things that you wanted to learn about between when I climax, and I can get excited again. After that, you can do the things that YOU wanted. So it's up to you two: if you want, both of you can see what happens when I get excited enough, and Karen can leave if she wants; then I can do things with Donna, and we finish with Donna doing things with me. If Karen doesn't want to see what happens, then Donna and I do whichever one she wants to first.
Whatever you decide is fine with me."
They looked at each other for several seconds, then exchanged a few whispers, before Karen told me "I'd like to see.", followed by Donna saying "I want to see, first, so I'm not surprised."
"That's okay — both of you. Now the only thing you have to decide is how soon you want it to happen, and whether or not Karen helps. If you want it to happen sooner, then it would help me if I could touch you more."
I got the answer to the second question when both of them scooted even closer — making it possible for me to reach them from their shoulders on down. What Donna was doing felt good, and my hands were still enjoying the feel of their tight asses, so I just kept going with what I was doing — at least, for a little while.
When Donna released me so that Karen could begin stroking my hard cock again, I figured that it was to me to raise my goals a bit; and more specifically, get my hands on their tits.
When I'd admitted to myself that the other things I'd done with them had been sexual, too, it was as if a weight had been lifted off of me. I was still committed to not doing anything to hurt or disturb them, but I felt like I was finally free to really participate in the things we did together.
So with both of them there with me, and both interested in seeing what happened when I climaxed, I didn't have any problem with seeking out the pleasures that would help make that happen.
Slowly and soft, I caressed my way from the smooth globes of their asses to their hips and waists. After a brief detour to delight in the softness of their bushes, I meandered my way farther and farther up their young bodies until I was finally able to start playing with two very different, but equally enjoyable, breasts. Donna's mammary was still larger than Karen's, but Karen had a slight advantage in firmness. For both, the way I softly drew my fingers from the base of her breast to the tip soon had two small nipples standing proud — one light, and one dark.
Once I'd gotten them to that point, it wasn't long before Karen decided that she wanted to have my erect cock in her hand again; when she started to reach for it, Donna simply smiled at her sister and released her grip on me. After shifting her position slightly, Donna moved to her hands and knees, then leaned over me so that her breasts were right over my face. I was happy to accept her invitation, and raised my head enough to take the end of the breast that I hadn't been touching between my lips, and start gently sucking on it. As I was doing that, I caressed my way down her body until I was able to cup her soft pale mons in my hand. I heard her moan softly when I let the tip of my finger dip between the soft folds of her labia; after wetting the end of it with her oils, I slowly drew it upwards so that I could begin softly and gently teasing her erecting clitoris
— which earned me another pleased moan from her.
It didn't take long for me to get Donna softly panting between the sounds she made as I continued to nurse at her breasts, and patiently toyed with her small pleasure-button. When I spared the time to look, I could see that Karen was fully aware of what I was doing to her older sister — and how Donna felt about it.
Donna had come to me enough times that I had a fairly decent idea of how best to arouse her, and help her have an orgasm. I happily applied myself toward making that happen, but with a little bit of a twist; as Donna got more and more aroused, the supply of her feminine juices increased — and I deliberately let her watch when I would collect a goodly sample of them on my finger, then transfer them to my mouth. The first time I did it, her eyes widened in surprise; but after that, I could see that it excited and aroused her a little more each time I did it.
About the time that I could feel myself reach the point that signalled I was on the "home stretch"
toward finding my release, I felt Karen's hand slowing slightly as she continued to stroke my penis. Another look her direction revealed that she was watching what I was doing to (and with) Donna, more than what she was doing to me. That gave me the idea to try something a bit different than the plan we'd started out with.
I increased the speed and pressure of my manipulations of Donna's clitoris to a point that I knew stimulated her tremendously, and it was barely a minute until I could tell that she was getting close to an orgasm. I waited until I knew she was almost there, then firmly (but carefully!) bit her nipple — effectively pushing her over the edge and into the chasm of a deep and powerful release that had her young body going through a series of powerful spasms. When it was over, I helped support her as I guided her to lay on her side while she got her breath back. Though I kept my head turned toward Donna, I could see from the corner of my eye that Karen was somewhat awed by what her older sister had just gone through — and a bit envious of it.
When her breathing had stabilized, Donna sat up again and looked down at me to say "Thanks, Uncle Ted — that was great!"
I smiled up at her before saying "I think Karen might like to have one, too, before she leaves…"; that was all the prompting Donna needed to change position so that she could nudge Karen's hand out of the way and start masturbating me again. When I turned my head to Karen, I saw that she was looking at me with an expression of uncertainty and desire. I knew how to deal with the desire, and addressed the uncertainty by holding my arm out in invitation.
In almost no time at all, she'd gotten herself to her hands and knees, and close to me; close enough, even, that I was able to gently guide her head down for the two of us to share a kiss — one that ended only after our tongues had played in each others mouths. When Karen pulled her head back from mine, there was a look on her face that I didn't quite know what to make of; it quickly disappeared, though, when I used my hand to tease both of her nipples to erection before sliding it down her belly…
When my hand slid between her thighs, Karen tilted her head back and released a pleased sigh before getting herself situated over me much as Donna had. Again, I welcomed the opportunity to lick and gently suck on the peaks of her breasts, and gently nibble them with my lips. Between her silken thighs, I had started softly drawing the tip of my finger across her opening before slowly easing it up enough to brush it across her erect clitoris. Just a very few passes like that resulted in enough of her oils leaking out of her for me to begin using them to keep from causing her any pain while I twirled my finger around her clitoris, interspersed with periods of gently pressing on it and a slow rhythm. That added stimulation dramatically increased the supply of her nectar; just as I'd done with her sister, I let Karen see as I licked them off my finger after I'd gotten it well-coated. Having seen me do the same thing with Donna, Karen wasn't surprised by it — but certainly just as aroused.
Younger and slightly less experienced than her sister, Karen didn't respond quite as quickly as Donna had; that only meant that I got to enjoy the delights of her young body for that much longer before I'd gotten her close to her own orgasm. Once again, I patiently brought her to the edge, only to push her over it by rapidly tapping her clitoris as I strongly sucked on the end of her firm breast; from my perspective, I figured that her release was easily the equal of the one I'd help Donna find.
After the pleasure had tapered off for her, I had to help Karen lay down, too; as she got her breathing back under control, the two of us looked into each others eyes; in hers, I could see the joy she felt at the experience she'd just had — and the love and gratitude she felt toward me for helping her have it.
Remembering that Karen wanted to watch as I climaxed, Donna had taken care not to stimulate me too much. Even so, I wasn't far from finding my release by the time Karen was able to sit up again and get herself relocated across from her sister — something that Donna took as her cue that it was okay to increase her efforts.
I think that both of them knew that I was getting close, and it both surprised and pleased me when I felt Karen's soft hand cup my scrotum, and then carefully roll my balls around inside it.
Knowing that both of them had a hand on my genitals was all it took for me to find my release; I barely managed to tell them "It's going to happen!" before the first jet of my cum erupted from the end of my cock, quickly followed by a second. I managed to draw a breath before the remaining surges of semen left me gasping.
Opening my eyes, I looked down toward the two of them to see what their reaction would be to what they'd just accomplished, and witnessed. Though both were clearly surprised, neither exhibited any sign of being put off by it. In fact, Karen watched as Donna brought her jism-coated hand up to her face to examine it; then after sniffing to see if there was any odor, Donna stuck her tongue out and used it to collect one of the larger blobs for a taste-test. After she'd considered it for a second, she crinkled her nose, but then opened her mouth and began licking her hand clean. That was all Karen needed to see before she used her fingers to collect what she could from one of the larger puddles on my belly, and perform similar tests. Karen apparently found the taste more appealing, since she didn't make any faces — she just went about wiping up puddles of my semen and depositing them in her mouth.
When they were done, both looked toward me — and only then seemed to realise that I'd likely witnessed what they'd done. Both blushed faintly, but when I didn't say or do anything to indicate that it mattered to me, they quickly settled down again. I opened my arms, and both of them quickly moved to lay on their sides and snuggle next to me. I rested my hands on their waists, and told them "Thank you, both of you. That felt really good."
I could hear the satisfaction in Donna's voice when she told me "I'm glad I was able to make you feel as good as you made me feel, Uncle Ted.", followed by Karen happily telling me "Yeah…
me, too. I was just surprised at how hard it came out, and how much of it there was!"
Donna laughed before adding "Yeah, it surprised me, too — but in a nice way.", prompting both of them to giggle briefly.
Several seconds went by before I heard Donna say "After I saw you tasting what MY wetness is like and how you looked like you liked it, I wanted to find out about yours. It didn't have any smell, like I have; and when I tasted it, it was kinda thick and salty. I guess it tasted okay."
