They both snickered again. His sister rested her hand on the point of Martha's hipbone and rubbed her thumb in the hollow at the base of her thigh, as she said:
"He was right about your hair."
"But your is nice, too, ... as much as anyone would want, ... like your breasts," and her hand found one, her fingers holding its fullness for a moment, squeezing it, and then finding her aroused nipple. His sister moved her thumb again with an appreciative sigh as her other hand slipped under Martha's waist - and hers did the same - and they both held each other's hips and moved their faces closer up the other's thigh. Martha's other hand slid up from his sister's her breast and towards her hip, and then they were both drawing each other closer, their faces sliding up between their open thighs. And then with a mutual sigh, they clasped each other together and burrowed their faces deep between the other's waiting thighs that lowered to hold the other's head as their mouths found the other's aroused pussy.
In the now brighter morning light, there was no hesitation about what they wanted. Clasped together in perfectly mirrored positions, their bodies hardly moving, just twitching occasionally as their tongues moved, hidden in each other's moist, aroused cunt, and moved in unison, better now than the first time, lapping and boring, and lapping and rubbing the other's firm, aroused clitoris in almost perfect unison. And in the same unison, their fingers slipped down into the crevice between the other's hips and found her asshole, both holding still for a moment as their fingers moved, and then their hips moved in unison, rocking up, and then relaxing, and then rocking up as they both moaned, and then moaned again more emphatically as they clutched each other and their thighs twitched, and then twitched again, fluttering, quivering, and then clutching and clutching again and again with wet noises, as they gasped and moaned, and then again and again as their hips jerked and their thighs quivered.
And then they just sighed loudly, and their bodies slumped, completely relaxed, just moving with their following deep breathing and sighs.
And then they just lay, breathing less deeply, and then their hands moved, stroking each other a little. One and then the other extended her leg, leaving the other's face free. Then they were still for a while longer. When his sister slid her hand down and found Martha's breast, holding it, Martha did the same. They fondled each other while one and then the other took a deeper breath, but then released it.
Then, finally, Martha drew another deeper breath and asked softly:
"Do you always ... come that good? That must have been wonderful."
"It was, thank you. ... Not until he did it for me. Don't you? It was so good, and knowing you were, too, ... that I was making it so good for you. ... I just loved it, ... like I thought I would, ... all in my face. I wanted that. ... Don't you?
"Not until he did it. ... Hnnn! Like you said. ... You're lucky, learning so soon. ... And I wanted you to, ... wanted to know it was being good for you and to have it ... like you said."
"All in our faces, like he likes it. Now I ... we know why he loves it so much. I do too."
Martha nodded. After a moment his sister continued:
"And oh, that was so good, when we were doing it together, it was almost as though I were doing it to myself. That was funny, but so good."
Um-hmm, like that. That occurred to me, too, ... yes, funny. ... Oh, thank you, too. I should have said that before. I guess I didn't want to admit how much I liked it."
Martha squeezed her breast, and she squeezed hers in return and replied:
"I'm so glad you did. It's just too good not to like it! ... Oh, ... I guess ...? Oh, ... I don't know, ... I guess, I just love it any way. ... I mean, ... well, I shouldn't have done it with him, ... maybe more than I shouldn't with you, so ...? Oh, I didn't mean that! I didn't want to say that! ... I mean, ... 'cause I shouldn't have done it with him, it wasn't any more of a taboo - breaking a taboo - to want to do it with you, ... and I did. Well, it was easier for me to admit I wanted to. ... Yeah, I think that's what I mean, what I wanted to say, ... that it was easier for me to admit to myself that I wanted to, that I liked it. Did that make sense?"
Martha snorted with a smile and nodded and agreed:
"I think so, yeah, that made sense, ... after you got there."
They both snorted, and then Martha added:
"Yeah, I think it does, sort of explains why it was more difficult for me to admit I did, ... that I do, too."
"Oh, that's good! Thank you, ... for helping me explain what I meant, ... and for agreeing that you liked it. ... I wanted you to, ... didn't want you not to, ... want to feel that maybe you really didn't want to, ... even if you did it - and so good - but then wished you hadn't."
"I might have, before you said all that. But now I can't help but admit that I really liked it. ... You're as good about talking about sex as your brother is."
His sister snickered and replied:
"You know where I learned.
"Hmm! Um-hmm. I did too, from him. I wonder what he thinks we are doing?"
"Right now? What we could be doing? What time is it? Maybe he's taking a shower - and washing it - ... hmm? - not like that, or maybe like that - and thinking we could be too, one of us, or both of us - showering - or already making breakfast, naked. Yeah, he probably thinks that, at least, that we have agreed to go naked, knowing we both would want to."
"Um-hmm, we sure did. And if he thought that, he must be wondering if we will ..."
"And probably pretty sure that we will. He knows us both pretty well."
"Well, we haven't disappointed him then."
"That sounds funny, two girls that have slept with him agreeing that they haven't disappointed him ... this way."
"Um-hmm, but he would understand and ..."
"And like it. Like with the roommates, ... or that other girl. He didn't mind that they did, and they were good, ... with him. Of course, if they liked what he likes, they must have liked everything, wanted him to do everything, ... anything he liked ..."
"Or they liked."
"Like us."
"I guess so."
"We do."
Martha squeezed her breast in response and was silent for a moment before she replied:
"But don't tell anyone."
They both snickered softly as they fondled each other's breast, and then his sister murmured:
"Not even him?"
"You probably won't need to tell him. He'll just know."
"Yeah, ... probably. ... I hope you don't mind?"
"I guess not. ... No, ... I kind of like the idea, ... that he thinks - would think - we have, that we were curious enough to ..."
"And liked it."
"Yeah, ... I guess ..., that, too."
"Oh, I do! ... Oh? ... I guess that's like before, ... that it's easier for me to say so. ... But I really hope you did."
Martha just nodded on his sister's thigh with a little snort, and then blew on her hair, and then snorted again and fondled her breast with another nod and replied:
"Um-hmm, but ... No 'but', ... it's just still a new idea, ... a little hard to admit. Oh, I think all girls would like it ... if they once did it, ... sort of like doing it to him the first time, but that was easier ... to admit I like. ... Hm-mmm! I really told him how much I liked that."
