For the next several minutes, the only sounds in the room were rhythmic, and liquid – until Sandra finally pulled away from me as she experienced wave after wave of pleasure when Robyn brought her to release. To my surprise, even as she was coming down from her orgasm, Sandra fought to make her way back to me, and take me into her mouth again.
Satisfied that she'd gotten Sandra off, Robyn eased her way into a semi-seated position, then leaned over to let me suck on her breasts and nipples as I continued to slide my finger in and out of her vagina, bumping against her clitoris with each inward probe. The sight of my wet finger sliding in and out of a gap in her dark muff was an incredibly erotic sight – doing wonders to help move me along toward the goal Sandra had set for me.
As I already knew, Robyn enjoyed using her mouth on me; from the rapid increase in her breathing after she sat up, I could only figure that she enjoyed watching someone do it almost as much she enjoyed doing it herself: it was just a couple of minutes later that Robyn went through her own release, nearly pinching my finger off with her internal muscles, and leaving a distinctly-scented wet spot on the bed, as well. When she'd gotten her senses back, Robyn rolled over toward the edge of the bed, both giving herself a good view of Sandra and I, and making way for Sandra to twist around so that her body lay closer to mine.
Looking down, I could see that Sandra was getting a little tired from her exertions, and with a few gently nudges, managed to get her to lay on her side, as I did the same. That also brought her pelvis closer to my head; I raised my leg so that I could put my foot flat on the bed, and guided her leg into the same position – leaving me free to examine and explore the center of her femininity. I leaned forward a bit, and sampled her sweet, musky oils at their source – she moaned at the first contact I made, and the sensation on my erection was incredible: I could feel the vibrations all the way down to my balls.
Sandra didn't have the skill Robyn did – but that just made the experience that much more satisfying: rather than 'pushing' me into a fast, hard climax, she was drawing me along toward one that I knew was going to be all the more intense for the delay.
I extended a finger to trace the outlines of her sex, and when she felt my touch, readily spread her legs to give me more access. As I'd found when I'd used my mouth on her previously, her labia weren't quite as long as Robyn's, but they were a bit thicker. They were barely visible between the lips of her mons, their edges blurred by the soft, thick hair of her pubis. When I slid a fingertip between her inner lips, I found them to be firm, and slick with her juices; toward the top of her slit, I could make out the size and shape of her erect clitoris: it looked very much like a small Navy bean, only glistening.
Since she so readily accepted the touch of my finger in and on her vaginal opening, I gradually increased the duration, and depth, of my probes of her womanly flower. I was pleasantly surprised when I eventually found that I could easily slide an entire finger in and out of her hot, wet opening – either she'd already lost her maidenhead prior to this, or it had been so thin that my initial probe of her had removed it. In either case, my attentions to her sheath drew an escalation of her moans as I progressed. A glance over at Robyn revealed that she had her eyes locked on the subject of my explorations; with one hand busy at her own opening while the other squeezed and pinched her breasts and nipples.
Changing the angle of my 'attack' slightly, I continued sliding my finger in and out of her vagina, but now it was rubbing alongside her clitoris, as well – earning myself another one of those incredibly stimulating moans from her. A moan that was more than enough to cause the tightening in my balls that told me my climax wasn't far off.
Sandra seemed to sense it, as well, and – as best she could, with the distraction I was giving her – increased her efforts to bring me to completion. When she moaned again, and felt my balls twitch in her hand, she realized what she could do to get me off – and did it. For the next 30 seconds or so, she moaned almost continuously, rapidly bringing me closer and closer to the edge, until, finally, she all but deep-throated me. The sensation of her throat clasping at the head of my already-sensitive penis was more than I could stand, and I felt the first tensing of my erection as I prepared to unload into her eager mouth and throat. She felt it, too, and held me there until she felt my penis twitch in her mouth before pulling back enough to breathe as I fired what felt like a quart of semen onto the back of her throat, quickly followed by a second, then third. Even as the rest of my cum emptied into her mouth, she continued to suck and lick on my penis, prolonging my pleasure.
In return, when I got my senses back, I refocused my attention on what I was doing to her – and short order, felt her vagina clamp down on my finger as she started yet another orgasm. Only when the first of several spasms passed through her did she finally release my semierect penis from her mouth When she'd gotten her breath back, Sandra sat up a bit, and looked at me with an impish grin on her face, before licking her lips and saying "Robyn was right: I think I could learn to like this – a lot!". With that pronouncement, Robyn didn't hesitate to move toward us again, and take Sandra into an embrace as they kissed, clearly sharing the bits of my semen that Sandra hadn't already swallowed.
After making sure they'd cleared each other's tonsils of my residue, Robyn and Sandra separated – Sandra to move herself up to lay next to me as Robyn attended to cleaning my now-flaccid penis with her tongue. As she watched Robyn, Sandra said "I can understand why Robyn likes to do that so much – it's really exciting to know that I can make you feel that good with just my mouth. And the way your stuff tastes is really interesting – it's salty, and kinda sweet, at the same time; and it comes out kind of like custard, or something."
Finally satisfied that she'd gotten every available molecule of my semen, Robyn moved up to lay next to me on the other side, nuzzling into my neck and saying "That was*so* hot to see, you two together!"
I laughed, and told her "Thanks – I'm just glad you found a way to keep yourself amused!", teasing her.
I could feel her blush slightly as Sandra asked "What? What was she doing? Playing with herself? I wish I could have seen it, too!" – and causing Robyn to blush even harder.
We cuddled there for probably half an hour before Sandra raised up enough to ask if anyone else was hungry – which prompted Robyn to chime in that she was. Feeling a little hollow, myself, I asked what they wanted; almost in unison, they asked "Pizza?". I thought about it a moment, and decided that it actually sounded pretty good. I volunteered Robyn to go order it so that Sandra and I could cuddle a little longer. When she left, I nudged Sandra, and when she turned to me, told her that I'd really enjoyed what she'd done. She blushed slightly, and told me that she'd been a little worried and nervous about it at first, but that between Robyn's guidance and my acceptance of what she was doing quickly calmed her down. About that time, Robyn came back in, and crawled onto the bed to lay on the other side of Sandra, her head resting Sandra's shoulder. Robyn listened as Sandra went on to tell me that she liked what she and Robyn had been doing, but that she wanted to "know the rest of it – you know, what it was like with a guy".
At that, Robyn reached around to cup one of Sandra's breasts before telling her "I like what we do, too – and in some ways, it's even better than what I feel when I'm with him. But in other way's it's not as good. I mean, it's like they're two completely different ways of having fun. They are, I guess, but it's like the way it even *feels* is completely different, too."
