Where?". She poked me in the ribs, and said "I can see that I missed out on something, too!", gesturing toward the bulge of my swimsuit.
About that time, we were interrupted by a big splash, shortly followed by a minor rainstorm of pool water – apparently, Robyn had taken the opportunity to do a 'cannonball' into the pool at the end nearest us.
I gestured toward the pool, and said "I think that was our cue to join in.", Lucy nodded her agreement, and I called out "Last one in is a rotten egg!" before making a mad dash for the pool. It caught her completely unaware, and it was a couple of seconds before she started after me, giving me the chance to dive into the pool just ahead of her.
The three of us splashed around in the pool for a good half hour; it was really a pleasant experience to be the center of attention of two well-build lovelies in bikinis. Robyn, as noted before, was an excellent swimmer; Lucy was doing a pretty good job, too. Somehow, I managed not to let myself drown – mostly.
Finally, though Lucy and I were starting to get tired, and got out of the pool to go and lay on the pool chairs. As we laid there soaking up the sun, Robyn continued to splash around in the pool, and make dives off the diving board. A while later, Robyn got tired as well, and came over to lay down with us. She started talking about how much she'd enjoyed dinner the night before. She finished up by saying that when she told Sandra about it, she'd be "soooooo jealous!". At the mention of Sandra, Lucy started a bit, and said that she'd almost forgotten to tell Robyn that Sandra was going to be coming to visit earlier than expected – that she'd be arriving the following Thursday, in fact. Robyn almost screamed in happiness at that, and started dancing around the pool – I looked over at Lucy, and she rolled her eyes at me, indicating that she thought that perhaps Robyn had lost her mind. I laughed, and told her "Remember what you said about another girl not being that much more trouble?", and she stuck her tongue out at me in reply, laughing when I made a kissing motion at it.
By this time, Robyn had worked her way back around to us, and flopped down on her chair again. When I turned to look at her, she gave me a Significant Look, and said "I'm going to be*so glad* when she finally gets here! I'm sure we're going to have so much fun!".
When some other people showed up for a dip in the pool, Robyn got back up, and joined their kids in some game whose rules wouldn't make a lot of sense to any adult, and involved a lot of splashing and swimming. Lucy and I stayed out in the sun, and after a bit, she got up and moved her chair closer to me, so that we could hold hands as we sunbathed. When she asked me if I'd put some sun block on her, it was all she could do not to laugh out loud when I asked "Can I use my tongue?". She handed me the lotion, and I started spreading it out on her shoulders. As I worked my way down her back, she kind of wiggled her hips, and when I got down to her suit bottom, started easing my hand under the edge of it as I smeared the lotion around. After she'd let me get my hand completely under her suit bottom, and give her ass a nice massage with the lotion, she turned over, and I could see that her nipples were erect, and poking through her top. She said "Do my front, too?", and laughed softly when I replied "I'd die to!".
I moved around so that my body was blocking her from the view of the other people, and as I applied the lotion to her, used the opportunity to slide my hands under her top and play with her breasts, making her nipples even harder. I couldn't spend too much time there, though, and I'm sure she was as sorry as I was when I slid along the chair, and started applying the lotion to her belly. She quickly perked up, though, as I allowed my hands to dip under her suit bottoms, and brush across her soft bush; and briefly slide across the outside of her vagina, pausing to give her clitoris brief little rubs. I still didn't want to draw attention to us, though, and didn't carry on like that for any longer than I dared. I could see a combination of relief and disappointment in her eyes, though, when I finally stopped. When I stood up, she could see that my penis had hardened considerably, and with a mischievous look in her eye, asked if I'd like her to 'do' me, too. I caught the meaning, and said "Sure – I'd love it!".
She had me lay down on my stomach first, and almost duplicated what I'd done to her: first applying the lotion to my shoulders, and when she'd gotten to my lower back, taking the opportunity to slide her hands under my swim trunks and squeeze my ass. When she was done with my back, she had me turn over – careful to keep herself between me and the other people, so that the couldn't see my erection – and started on my front. When she got down to my belly, she didn't even hesitate to slide her hands under the waistband of my suit and start rubbing my erect cock, and slide her hand even further inside to caress my balls.
She, too, understood the need to make it look innocent though, and soon finished applying the lotion, letting me turn back over onto my stomach to keep my erection from becoming obvious to the other people. When she'd laid back down on her chair, she turned her head toward me, and said "You know, that has got to be the most erotic, sexiest thing I've ever experienced – what you did to me, and what I did to you; right out here in front of all these other people!". I smiled at her, and told her "That's one of the nice things about sensuality: it can be an aphrodisiac all on it's own."; she nodded her understanding, and with a gleam in her eye said "With stuff like that to encourage me, I don't think it's going to take as long as I'd thought!", meaning her wish for us to become intimate. I smiled in return, and took hold of her hand as we laid there for another couple of hours before heading back to our respective apartments hand in hand, leaving Robyn playing in the pool.
Part 4
About 5:00, Robyn's mother, Lucy, stopped by to tell me that she had to go do her grocery shopping, and ask me to keep an eye on Robyn while she was gone. 5:30, or so, Robyn came over and asked where her mother had gone, and after I told her, asked if she could use my shower to rinse the chlorine and such from the pool off. I said "Sure, go ahead", and didn't any more than have the words out of my mouth than she had pulled her bikini top off, and started tugging her bikini bottoms down, right there in front of me. I wasn't disappointed by this, of course, but it still surprised me a bit.
With a wicked little smile on her face, Robyn headed in to take a shower, wiggling her cute butt at me the whole time.
I heard the shower shut off a few minutes later, and shortly after that, Robyn calling to me, asking me to bring her a towel. I got one, and when I started to hand it in to her, she grabbed my wrist, and pulled me into the bathroom with her. She asked me "What's the matter? Don't you want to spend any more time with me?". I assured her that I most certainly did, but that I didn't think that we had enough time to really have any fun before her mother got back. She asked when her mother had left, and when I told her, said that her mother almost always took an hour to do the shopping, even though the grocery store was only a couple of blocks away – and then added that she figured we had another 15 minutes, anyway. With that, she leaned back against the sink, spread her legs, and started caressing her clitoris and the outside of her vagina; in just a few seconds, I could see her vaginal lips were extended, and her clit was starting to show itself, as well. I could also see that the excitement and cool air had hardened her breasts, making her nipples stand up like little volcanoes.
My cock started getting hard, and when she saw the bulge in my pants, stopped what she was doing, dropped to her knees, and started unfastening my belt. Realizing that we didn't have much time, I pushed her hands away, and started unhooking my belt myself; she used the opportunity to unzip my pants, and when my belt was free, unfasten them and pull them down to my knees. With only my underwear left, she quickly reached up and pulled the front of them down, so that they were 'latched' under my balls, opened her mouth, and sucked my entire penis in. When she started moving her head back and forth, and massaging my cock with her tongue, it wasn't long before I had gotten hard enough that she couldn't keep the whole thing in her mouth; settling instead on sucking me in far enough that the head of my erection softly hit the back of her throat on each inward stroke. After just a couple minutes, though, she stopped, and looked up at me saying "I'm still on my period, so we can't do any more". I nodded my understanding, and she promptly went back to sucking my still-wet cock, and rubbing different parts of it with her tongue when she had most of it in her mouth.
