Neither showed the slightest hesitation in turning toward me and giving me a full view of their lithe young bodies as I handed them their suits.
Sandra spoke first, telling me that Robyn had told her about me, and how much fun Robyn and I had had. Robyn then chimed in by telling me that she knew her mother and I had "done it" the previous evening while the two of them were at the pool. I said that we had (no point in denying it), and Robyn replied by saying she was glad that I was able to make her mother happy, and she hoped that I would be able to "make me and someone else happy, too."
From the look of hesitant anticipation on Sandra's face, I could tell that she was the `someone else'. Sandra came out and said that she thought what Robyn and I had done sounded fun, and that she thought she wanted to try it, too, but that she was afraid of getting hurt. Robyn told her that it might hurt a little, but that I was very careful and gentle, and that it wouldn't hurt much, and that the feelings she'd get would be wonderful.
Sandra still looked a bit dubious, but also more interested. Robyn told her that I really was very careful and that I'd been the one to take her cherry, and that she (Robyn) wouldn't be jealous or anything – she just wanted Sandra to have fun like she did. At that point, I interrupted by saying that something like that was going to have to be Sandra's decision, and that I wasn't going to be doing*anything* unless and until Sandra was really ready for it; so Robyn should quit trying to push her into it, and let Sandra decide for herself.
Robyn pouted a bit at that, and Sandra looked a little relieved; after a few moments, Robyn said that even if Sandra wasn't ready yet, that didn't mean that she couldn't at least find out what a man looked like, and suggested that I join them in the shower. Sandra looked interested and agreeable to this, so I decided to go ahead and join them – it isn't often that one gets to have two lovely young females for shower toys!
As I was undressing, Robyn frankly watched me while Sandra feigned disinterest – at least, until I started to take off my underwear. Once naked, I quickly joined them in the shower, where Robyn didn't hesitate to grab hold of my penis and start playing with it while I got myself wet under the shower head. When I was about half-hard, Robyn let go of me, and told Sandra to go ahead and try it – after a few moments of hesitation, she did so; very delicately at first, but soon with more confidence when she realized that she wasn't hurting me.
Once Sandra was more comfortable, Robyn started telling her some of the things that she'd learned – that the testicles were sensitive to pressure, how the area behind and under the head was very sensitive, and so on. Then Robyn suggested to me that maybe I could start touching Sandra, so that Sandra could find out what it felt like to have someone else touch her.
Sandra quickly looked up at me, and when I smiled at her and raised an eyebrow in question, decided that it would be okay, and nodded to me. I slowly reached out, and put my hands on her shoulders – which surprised her, I think – and started giving her a mini-massage. Only when she relaxed a little did I start moving my hands in larger motions, so that I was eventually caressing her breasts and making her nipples stand up like pale pink pebbles. I could see her breathing start to quicken, and I gradually moved my hands down so that I was caressing and squeezing one of her buttocks with one hand while the other made slow, gentle explorations of her pubis.
When my hands left Sandra's breasts, they were replaced by Robyn's – I could see the smile on her face as she stood behind Sandra and held her breasts, cupping them and playing with the nipples.
As Sandra's breathing got even quicker, and she became more and more engrossed in what she was doing with my now- erect penis, I started slowly moving my hand farther and farther between her legs, until I was finally able to start softly stroking her vaginal lips, and making gentle rubbing motions against her clitoris. It wasn't long before she moved to spread her legs a bit, so that I could reach her more easily. I felt her tighten up a little the first time I moved my finger between her vaginal lips and into the opening of her vagina, but when she realized that I wasn't going to do more than that, she soon relaxed again.
After only a couple of minutes, her pelvis started moving, and she started making low moaning sounds in her throat as I tended to her vagina and clitoris while she continued to stroke and caress my penis and testicles. It wasn't much longer before her attention was completely on what I was doing to her vagina, and more importantly, to her clitoris – she completely forgot what she was doing with my penis, and simply stood there, holding it as I focused more and more on her clitoris.
After only a couple more minutes, I could feel her tense up as her climax started – she would have collapsed with the first spasm if it hadn't been for the fact that she was leaning against me, and Robyn was helping to hold her up by continuing to hold and caress her breasts. Sandra's legs clamped around my hand, making it difficult for me to continue to softly massage her clitoris as she climaxed, but I was able to do so by making only small, gentle motions of one finger in time with her contractions.
When her orgasm finally ended, and she realized where she was and what had happened, she looked up at me in fear and confusion; I smiled at her, and told her that I was glad that she'd enjoyed what I had done, but that I wasn't going to do anything to her that she didn't want me to. She seemed relieved at that, and blushed as she told me "thank you – that felt *wonderful*; even better than when I do it!" before blushing even harder. I laughed and Robyn told Sandra what I'd told her – that anyone who said they didn't do that was lying. With that, Sandra smiled and turned to kiss Robyn – a kiss that seemed to heat up considerably as it progressed.
When it finally broke, both girls looked at each other in a way that seemed to say that there was more to come. Robyn turned to me and said that it wasn't fair that Sandra got to cum, but I didn't, so she was going to "take care of" me – and with that, kneeled down in the shower, and took my still-erect cock into her mouth as Sandra looked on in surprise.
As Robyn started sucking on me, Sandra quickly got over her surprise, and then got a rather thoughtful look on her face before kneeling down behind Robyn. I could see it as Sandra reached around Robyn with one hand to play with her breasts while the other moved farther south to begin administering to Robyn's vagina and clitoris.
As Robyn got more and more excited, she got more and more enthusiastic about sucking on my cock, and it wasn't long before she was taking nearly the entire length of it into her mouth as she jerked her hips in time with Sandra's actions. The feeling of Robyn's warm mouth around my cock, and the sight of Sandra's naked body as she made love to Robyn was enough to bring me to the very edge of shooting my load in no time; when Robyn felt my balls tighten up, she pulled her head back so that only about half my erect cock was in her mouth, and started using her tongue to tickle the head of it – and in turn, causing me to shoot load after load of my sperm into her eager mouth, where she swallowed every drop of it. After the last wad of my jism had gone down, she released my penis from her mouth, and turned slightly so that she could give Sandra a deep kiss as her orgasm hit her – a kiss that they kept going for the entire duration of Robyn's climax.
