It took only a few more minutes before Wendy apparently felt recovered enough to try and return the favor Donna had done her. Rolling onto her side so that she was facing the older girl, Wendy looked into Donna's eyes and said "Would it be okay if I did that for you now? I know I won't be as good at it as you, but I'll do the best I can…"
Holding Wendy close, Donna rolled onto her back, pulling the younger girl on top of her before answering "Of course it would be okay, Wen. And don't worry about how good you are; I know you love me, and you'll be making me feel good, and that's all that really matters — okay?"
Pleased, Wendy nodded before Donna pulled her head down so the two of them could exchange a number of small, soft kisses. As they kissed, Wendy began running her hands over her sister's body — paying particular attention to Donna's larger breasts. Over the course of the next several minutes, Wendy learned how to pleasure her oldest sister with her hands; then she decided it was time to do the same with her lips. After she'd nursed at Donna's breasts long enough to bring both of them to erectness, she began licking her way down the older girl's body. When she got to Donna's pale forest, I could see that she was delighted by how soft it was; but I knew she also had to be able to smell Donna's excitement even better than I could, and that was enough to draw her head even lower.
I watched as Wendy took a few seconds to really see what Donna looked like between her legs before slowly lowering her head as she began to extend her tongue. Because of Donna's raised knees, I couldn't see how Wendy made contact, but when it happened was signalled by Donna's soft gasp of pleasure.
As Wendy began to learn how to pleasure another girl, Donna gently guided her, and offered helpful suggestions — "Yeah, there is good" and "You can do that a little harder, if you want" and "That's nice, but it would be better if you did that a little faster" were just some of the things I heard her say.
Wendy was apparently a quick and attentive student, since there weren't that many things Donna had to tell her; sooner than I would have thought, Wendy had gotten the older girl to the point that I doubt she could have said much, anyway — she was simply too busy moaning and gasping.
Though it took her longer, and the results weren't as dramatic, there wasn't any doubt when Wendy finally managed to bring Donna to an orgasm. When she pulled her head from the older girl's thighs, Wendy looked inordinately pleased with herself as she moved to lay next to Donna, and hold her. Naturally, Donna recovered more quickly, but wasn't any less appreciative of what Wendy had done than she'd been of Karen's (or my) efforts. She didn't hesitate to hug Wendy close, and kiss her, before telling her "Thanks, Wen… that was really nice." Wendy looked pleased as she could be at hearing that she'd made her sister happy.
It had been long enough for me to be able to respond to the incredibly erotic show that Donna and Wendy had just given Karen and me. I knew Karen could feel my reaction because she was slowly twisting her body in front of me so that she was rubbing the head of my semi-erect penis.
After giving me a mischievous glance over her shoulder, Karen told her sister "Wen, it isn't just girls that you can use your mouth on. Donna and I have both done that for Uncle Ted, too. Do you want to see how that works? And if you want to, you can even try it, too, a little bit — but I should probably be the one to finish him, so I can show you what happens. Would you like that?"
I saw two pairs of nipples erect before Wendy licked her lips and answered "Um, yeah, I would.
Seeing how you do that, and… and maybe trying it."
As Karen got up to sit next to me, Wendy moved to take a position on the opposite side; then Karen had me slide down so that I could lay flat on the bed. With me in position, and Wendy paying rapt attention, Karen graced me with a smile before leaning over and taking my semi-erect cock in her mouth. It didn't take her but a very few minutes (damn she was good, even at fourteen!) to get me almost completely erect before letting me slip from between her lips.
Looking up at Wendy, Karen explained "His penis doesn't really have much of a taste — it's more like just like when you lick someones clean skin. Unless he's been doing things, of course!
Then he'll taste like wherever his penis has been — if it's inside me, he'll taste like me; if one of us has used our mouth on him, then he'll just taste like his semen. That's kind of thick, and tastes a little bit salty; I really like it, but Donna says she doesn't like it as much as I do, but she'll still let him climax in her mouth. When he does that, his semen — his juice — squirts out the end, usually pretty hard, unless he's already had a climax not long before. There isn't a lot of it, really, but it sure seems like there is, most of the time. When I finish him, I usually keep my mouth on him so that I can swallow all of his juice — but this time, I'll take my mouth off right before so you can see what happens. When you know he's getting close, you can hold his testicles in your hand; when you feel them pull up next to his body, he's close, and when you feel him suddenly get harder, that's when it's going to happen — just so you know. He still isn't completely hard, but I wanted to let you know this other stuff before I got too busy. I'll be doing stuff that I know Uncle Ted likes, but what you can do is just try different things and see what a guy likes -
sucking on him, using your tongue in different ways and on different places, even maybe carefully using your teeth. But generally, you don't want to let your teeth touch him, and it's better and easier if you leave some of your spit on him; it keeps things slippery, and makes everything feel better for him. You'll see me use my hand on him, too… that's called 'jacking him off'; if you do that until he climaxes, it's called a 'hand job'. Using your mouth on him is called a 'blowjob' — I don't know why, since you suck, not blow. Anyway, I like to make him climax like this, so I'm telling you all of this now so I don't have to stop and explain things while I'm doing it. Just let me know when you think you want to try it."
Wendy nodded her understanding and agreement, and Karen got her lips wrapped around me again. A couple more minutes, and I was fully erect as she slowly bobbed her head up and down on my manhood.
I think (hope!) that Karen was just "killing time" until Wendy was ready to have a try; she was doing an exemplary job of making sure I stayed hard while showing her younger sister some of the more obvious things she could do — treating my erect cock as though it were an ice cream cone and trying to lick me to death; trying to get her lips wrapped around me from the side, and sucking on me that way; slowly bobbing her head up and down as she clamped her lips around me; even "just" sucking on the head of my cock while she leisurely jacked me off. As she shifted from one thing to another, Karen would pause long enough to briefly let Wendy know what she was going to do.
I had to watch as Karen demonstrated fellatio to her younger sister, just as I had to look at Wendy several times to see what she thought of what Karen was doing. In the latter case, it was pretty clear that she found the sight arousing — she'd developed a faint flush, her nipples had erected, and she was breathing in little pants. I could also detect an aroma that was different than Donna's or Karen's — and hoped that I could sample it myself, one day.
Watching the two of them while being the recipient of Karen's considerable oral talents was beginning to have an effect on me when I saw Wendy lean forward, then heard her say "If… if it's okay, I'd like to try now…"
