I wasn't feeling any particular need or desire to cum, and Daneesha was doing a fine job of keeping me hard and herself entertained, so I figured it was a perfectly good time to see just how hard I could make Tania climax.
I'd gotten Tania to the edge and backed off once when Daneesha went through another orgasm; the sight and sound of her sister forced a sound of frustrated arousal from Tania as I resumed teasing her again. I brought her to the brink again, and was holding her there when I felt that Daneesha was getting close again. From the way she was responding to the sight she had of Daneesha bouncing on my dick, I knew that if I could get the timing right, I could practically guarantee her an orgasm she'd never forget. So I carefully began toying with her clit again, using the tip of my tongue, with the increasingly frequent sensation of Daneesha's vagina tightening around me as my guide. Tania was groaning and pressing herself down onto my face when I felt Daneesha starting her third orgasm since she'd gotten my dick in her. I started fluttering my tongue across Tania's clit, and heard her all but scream in pleasure even as Daneesha was trying to see how much of my dick she could get inside as she started her own climax. I made Tania's orgasm even more powerful by using my tongue to draw firm circles around the hood where her clit had disappeared; with each wave of release that ran through her, she was almost gushing, her vagina was pushing her juices out so hard.
I was still licking up Tania's oils when she lifted one leg and did a controlled crash onto the sofa-bed – and managing to do it without kneeing me in the head, or causing herself or anyone else any physical harm.
With Daneesha visible to me again, I could see that she'd finally managed to tire herself out: she was content to simply hold herself still on my erect cock, breathing heavily.
With Tania lying on the bed next to us, I was able to reach out and put my hands on Daneesha's legs again. It took her a few seconds to realize that I was touching her again, and to look up at me before I told her "You look like you're pretty tired. If you want to keep going, I think it'll be okay if I'm on top, now."
Her immediate response was to nod in agreement that she was tired; it took a couple of seconds for the second part of what I'd said to sink in for her. When it did, though, she immediately perked up and asked "We can keep going?"
I couldn't help grinning before I answered "Yes, we can keep going, if you want. You seem to have gotten used to having me inside you, so I'll be on top, and doing all the work for a while." With the mention of her having adapted to my larger penis, I saw a darkening of her lighter skin that I was sure was a blush before she answered "Uh, yeah, I'm okay with you in me now, so sure, I'd like to, uh, keep going."
I got her to lie down on top of me, and got us rolled over so that our positions were reversed without our having to uncouple – something that I could see pleased her greatly. A little minor adjustment of our legs, and we were ready for me take over being the active one.
My first considered action was to slide my penis out of her until only the head was inside her before slowly pressing myself back into her in a single long stroke – accompanied by her soft moan of pleasure. With the whole point of the exercise (no pun intended) being to convince her to be much more selective about her partners, I decided that it wasn't out of line for me to pass along a few things for her to think about, as well. So when I was completely filling her again, I told her "I could tell you liked that, so I want to tell you something."
She looked up at me expectantly, and I said "Good sex isn't about how many times you can climax. It's about taking your time so you can enjoy it, and making the climaxes you DO have better."
Even though she nodded that she understood, I didn't think that she really appreciated what I was telling her, so I decided that a little demonstration was in order.
Over the next several minutes, I consciously and deliberately went about thrusting in and out of her so as to slowly build her arousal and excitement in a way that she wouldn't have experienced before. My strokes where long and slow, and each time I thrust into her, I'd give an extra little 'push' when I was all the way inside her, applying a bit of extra pressure to her clitoris. Her legs were too short to allow her to lock her ankles, but she still managed to wrap her legs around my waist, opening herself to me completely. It wasn't long before she was arching her hips up in welcome to my thrusts, and making any number of small noises of pleasure as I slowly built up the excitement that would culminate in her orgasm.
As she got closer and closer to release, I gradually changed what I was doing: my movements in her became slower and longer, and the pressure I applied to her clitoris became a little stronger; I managed to bring her to the edge of a climax and hold her there through a couple more cycles before she slipped over the edge into a deep, deep release.
Her entire body froze under me for several seconds as she released a long, deep groan of pleasure before drawing an equally long, but shaky, breath – only to have her body freeze up again from the intensity of the pleasure she was feeling.
Around my cock, her vagina was going through a series of spasms that started at the base and ran toward the head, as though she was trying to milk it. It felt terrific, and moved me a lot closer to the point where I'd empty myself into her – but that was still a little way off, yet.
Even as she was experiencing what I suspected was the most intense climax of her young life, I was throwing gasoline onto the flames of it by continuing to press myself against her clitoris in time with the spasms I could feel running through her.
Even with her youthful energy, her body could only orgasm for so long; the waves of pleasure running through her gradually tapered off, leaving her shuddering and gasping for air.
Next to us, I heard Tania's awed voice say "Holy crap! After that, I don't think she'll ever want to fuck anybody but you! If I hadn't seen it, I wouldn't believe that a girl could climax that hard!"
I turned my head to give her a lecherous grin before telling her "If you want, I can do it for you, too…" – and couldn't help laughing at the way her eyes got wide at the mere suggestion that she could experience something like Daneesha had just gone through. She gave a little shake of her body and answered "I don't think I'd better – otherwise, you'd never get me to go home!" with a small laugh of her own.
I felt Daneesha move under me a little, and I quickly turned my attention back to her – and saw that she was visibly stunned by what she'd just experienced.
I lowered my body enough to kiss her to help her get her focus back; when I pulled away from her, her eyes were locked on mine. Several seconds went by, and after a couple of abortive attempts to speak, she finally managed to ask "You did that on purpose, didn't you?" in a voice barely more than a whisper.
I nodded, and said "I wanted to show you what I meant about taking your time, and having better climaxes instead of more of them."
She considered that for a few moments, and then told me "Well, you showed me – real good! That's one lesson I'm never going to forget – but don't do it again, okay? That was way more than anything I thought even could happen, and it scared the crap out of me. Jesus, it felt incredible, but it was still scary."
I assured her that I wouldn't, and kissed her again, and got kissed back. When I had raised myself over her, I began to slide my cock back out of her – only to see her eyes get positively huge with the realization that I was getting ready to fuck her some more.
