I hope readers love Martha and my sister as much as I did, also as individuals, and can enjoy that they discover that two girls can also enjoy each other. At the end of the week, I join them, but it will be a few chapters later.
After his parents left, Martha took her bag into his older sister's room. His sister had already said that she was going out to sunbathe, so she got out her bikini and put it on. Then she put the six-pack and two cans of beer in the refrigerator and found a towel and went out on the deck to join her. She was lying on her stomach with her bikini top unhooked, and the straps under her arms.
Martha lay down and reached back and untied her top, and then after a moment, undid the bow behind her neck. His sister turned her head and smiled and then said:
"Hi. This is just great, that you can come out here too. For me too, I'm going to have the best tan I ever had."
"Um-hmm," Martha agreed, smiling back: "... for me too. Nice that your parents suggested that I could."
"It was my idea, but it was great that they agreed. ... Oh, you should have some suntan lotion, at least to start. I'll get it."
She held her top and got up and slipped her arms through the straps, just adjusting it without fastening it. and went back in the house and returned, saying: "Here, I'll do it for you." "Thanks," Martha replied.
His sister started to lean down, and then snorted when her top started to slip and fastened it before she rubbed the lotion on Martha's back and legs, and then lay back down again and slipped her arms out of the straps of her top as she smiled at her again.
"Thanks," Martha said again, smiling back.
"I didn't wear my bikini when my parents were here."
"Thoughtful of you. You did with your brother?"
"Of course, wouldn't you with yours?"
"Of course, even with my parents, when I had one. I guess they're more liberal than yours."
"One like that? My parents certainly wouldn't have liked that. Bet your brothers did, though."
"I didn't ask them, but I guess I didn't mind their seeing me in it."
"Wanted them too?"
"Didn't really think about. Oh, I was pleased that I could wear it, you know, that there was something in it."
His sister chuckled with a nod. Then Martha did, remarking:
"Oh I guess I did want them to see it - see me. Long before I had a bikini, when I got my first bra ... I guess all girls want to. I didn't think I really needed it, but Mother said I had to, ... when school started."
"What did you do? Show it to your brother? Which one?"
"How did you guess? The younger one, both older than me."
"Really!? Just like that? In just your panties and bra?"
"Um-hmm."
His sister sat up in her surprise, forgetting her top as she asked again: "Really? Oh!" and she blushed and picked up her top.
"That doesn't matter," Martha said, smiling at her, and rolled onto her side and raised herself up on her elbow, leaving her top behind. His sister looked less embarrassed and snorted with a grin and put her top back down as she looked at Martha's breasts and replied:
"No one can see us."
"Looks like the sun saw you a lot, however."
"Oooh! He didn't tell you, did he?"
"That you wanted to go topless in France."
"He did?!"
"Looks like you did here."
His sister blushed, nodding, replying:
"He said he couldn't stop me."
"Hm-hmm! Could have been an interesting struggle."
"He didn't. You don't mind if we do?"
"No, sometimes we go topless in Norway."
"Oh, that's good, nice. Want some lotion on yours?"
She handed the lotion to Martha, who sat up and spread it on her breasts and elsewhere. His sister watched her with a smile and then looked more serious and asked:
"If you talked about that, ... uh, ... well, ... I guess you got on well together."
"Um-hmm. Told me your parents were worried that we might get on too well."
Martha's nipples had popped out, but they both were looking past each other. Then his sister murmured:
"I kind of got that impression too, from a few words I overheard."
Her nipples had also popped out. They were silent for a few moments, their nipples relaxing. Then his sister's popped out again, and she blushed. Then Martha's tightened again. She rubbed her arm over them and then murmured:
"They were right," still looking at the horizon.
It took a few moments before his sister found her tongue:
"Oh? I hope they didn't find out!"
"I do too, he does too."
"Must have been tense driving home with them. ... You did?"
"Yes, we did ... sleep with each other."
"Sure hope they didn't find out."
"Me too. Surprised?"
"Hmm? Not really. Well, yes, but I could imagine that it could happen."
They looked at each with slight smiles. Martha said:
