Melissa was laying on the beach in her favorite place, where the beach was secluded on both sides by patches of mangroves. It seemed to her like it was sort of cozy. It reminded her, in fact, of a pillow fort in the living room, making a small place out of a larger one.
Usually she was alone, but she was not alone this time. Sandi was lying next to her. They were both nude, both tanned, and both relaxed.
It had been a challenging few days, especially for Sandi. Sandi had come to better understand what it meant to be a sexual plaything, and not just because of what Melissa was teaching her. After spending part of the morning learning what a rim job was and what it was like to give one, she got to find out what it was like to eat pussy for an audience. She also got to find out what it was like to have a pretty big penis stretch her anus and invade her bowels. The afternoon with Max had been similar to the morning. She was better prepared, having put in a much larger butt plug before lunch and being better prepared for a reaming in the afternoon, but it was still a stretch. Literally.
Max had wanted to have another go at her ass, as Sandi had anticipated. It was a still sore from the treatment it had received before lunch, but she had lubed up well and used a larger plug, so that if he again used her there again it would not be so bad. It helped a lot.
Sitting in a chair, Max called her over. "You have a strange combination of eagerness and innocence, you know? I like that."
Sandi looked down, not sure how to respond.
"See if you can get the whole thing in your mouth this time. I'll be more patient."
Melissa watched from behind as Sandi leaned over and put his cock in her mouth. She could see Sandi's vagina and the butt plug, and saw her breasts hanging. She imagined that was what it looked like when she did that sort of thing, and the thought unexpectedly excited her. She resisted an impulse to reach out and stroke Sandi's labia and instead walked around to look at Sandi as she started to suck on his cock.
Sandi did not try to tease or build up to anything. He was already hard, and she just tried to get him in her mouth all the way. She got him down partway, had to pull out, but tried again. She got him in as far as the back of her mouth, the entrance to her throat, but could not go the rest of the way. She did this several times, and then she held him there and forced him in, into her throat.
She did not get him in all the way, and she had that stomach lurch that made her choke, but after pulling out, she pressed down again and got him even further in. She held it for a moment, pulled out, but went after it again and got him all the way in. She managed to hold it for a little while before she pulled out. She repeated this over and over, getting him all the way in and holding it, until he said "Good job."
He had not told her to stop, exactly, but she correctly understood that she had passed some kind of test. She looked pleased with herself. Melisa felt proud of her too, in a way, though she was also feeling left out and even a little jealous.
"Turn around."
She did.
"Spread your legs a little, and bend over some. I want a good look."
Sandi did what she was told, but it felt very exposed, somehow, to have her vagina and ass right in someone's face being examined. She had the butt plug in, but that did nothing to make her feel less exposed. She found herself feeling a little embarrassed. She was also looking at Melissa, who had walked back around and looked on with some interest.
Melissa was used to being the object of attention with the various visitors to the island. She felt slightly left out now, which surprised her. She also felt quite interested, enjoying her role as a spectator. Most surprising, to her at least, was the fact that she was also pretty aroused. She had first noticed that when she watched Sandi squirm on the wishbone. She was impaled and tied down so she could barely move, but her writhing efforts and the sheen of sweat that formed on her taut body had really turned Melissa on. She had felt a little of that when Raymond was tied and had the hair on his balls and crotch removed, but she was also uncomfortable being the person doing it. With Sandi, she was just watching and it was more exciting to her.
She watched Sandi's face as Max removed the plug. Her eyes grew wide, and she formed a silent "O" with her mouth. She relaxed a little when it was out, but then Melissa saw him grasp Sandi's hips and guide her back towards him. Sandi's face was a study in concentration as she was guided to straddle his legs and lower herself onto Max's cock.
Melissa watched with fascination as it slowly disappeared in Sandi's anus. Sandi still looked like she was struggling to get it in there, accommodating as best she could as she went. She had a look of relief on her face when she finally bottomed out and she relaxed, trying to get used to being stuffed with cock.
Melissa could only see Max's balls beneath Sandi's wet slit. He spread his legs some, which caused Sandi's to spread that much more. Her vaginal lips, much larger than Melissa's, were spread a little on either side, looking like a butterfly or an orchid of some sort. They glistened with her fluids. Her eyes looked a little glazed. Her mouth still formed an "O".
Melissa got on her knees between Sandi's legs. With her tongue, she licked up the length of her vagina and ended with a flick on the sensitive little nub at the apex. Sandi jumped, or as much as she could with a good sized cock in her ass. Max reached around and grabbed her tits, pinching the nipples with their little rings. They were still a little sore from their piercing but she was so aroused at this point that she just found it more arousing.
Melissa took both of Sandi's labia between thumb and forefinger and pulled them apart, exposing the wet pink inside. She used her tongue to lap up and down, stopping at the little clitoris on every pass. Sandi could not sit still, and her squirming and jumping resulted in her working the cock in her ass such that she fucked it while it fucked her. This was starting to have an effect on Max, whose groans served as the bass line to the song that Sandi was singing with gasps and little squeaks.
Melissa was reminded of a time not that many months ago when her asshole was impaled by Mr Thantos' cock while Lisel ministered to her vagina in exactly the same way. She had been so afraid that she would have to even touch Lisel, much less go down on her. That seemed silly to her now. She enthusiastically worked to pleasure Sandi, which in turn pleasured Max.
