Mentally shrugging Roban smiled at her. "Guess it's obvious I don't know much about this."
Chalissa smiled back at him. "Don't worry Roban; you'll learn fast and we are here to teach you all you need to know."
Taking a deep breath Meyra grinned and said, "OK, I think I'm ready to go."
With that she moved up again, way faster than before. Just as the head of his cock was about to leave her body she pushed down again. Down was less smooth, but still faster than before. Wide eyed Roban watched and thought, could anything ever feel better than this? With every downward movement the ride became smoother and the wild eyed expression on Meyra's face returned, accompanied by heavy panting and moaning.
Smiling at the look on his face, Chalissa took one of his hands and led it to Meyra's swinging tits.
"Don't squeeze too hard, and play with her nipples. I'll show you how she likes it."
Chalissa cupped Meyra's other tit with her hand and gently squeezed, Roban followed her example. Meyra's moaning increased, caused by the new fondling of her tits and her panting became even faster.
"Now pull on her nipples like I do."
Chalissa pulled the nipple between her thumb and forefinger until Meyra's round breast became almost conical, much harder than Roban would have dared. Meyra was continuously moaning, sweat streaming down her face and the pale skin of her chest and face had turned almost crimson.
"She's close, now pinch her Nipple hard and watch her", Chalissa whispered in his ear.
Roban pinched as hard as he dared and winced at the resulting wail of agony coming from Meyra. Her whole body froze, arching her back in a bow and throwing her head back she screamed again and pushed down so hard that Roban could feel the tip of his cock opening her cervix. A vice like grip all along his cock followed her scream and then he felt a rhythmic squeezing of his cock, as the walls of her pussy pulsated in her climax. Roban's eyes couldn't get any wider. Meyra fell forward on to his chest, resting her head on his shoulder. Shudders still ran through her body every few seconds and her pussy continued to squeeze and pulsate around his cock. Roban was in heaven. Slowly Meyra calmed down breathing deeply. Roban couldn't hold back, he lifted her by her shoulders and looked at her face.
"Do that again!" He blurted out. "That was incredible, magic! Yeah, you have a magic pussy. Do that again please!"
Although Meyra's head was hanging limply between her shoulders, she had to laugh.
"I'll do that again gladly, but I need a little rest first."
Suddenly she lifted her head and looked at him curiously.
"Why didn't you cum? You're sixteen! A warm breeze should make you cum! You let me ride you for half an hour and cum on your cock like a starving succubus, but you didn't cum yourself. That's impossible!" To test she squeezed his cock with her pussy and Roban moaned. "Still as hard as when we started!"
"You told me I'm not allowed to do anything unless you'd tell me to do it, and now you are complaining I didn't cum!" Roban grunted frowning at her.
Dumbfounded she looked at him. "I tell you not to cum, and you don't cum? That's it?"
"Didn't want to piss you off again," Roban shrugged.
Now both girls started laughing hysterically. Although he felt like the butt of a joke, he enjoyed Meyra's laughter immensely. Her pussy did marvelous things to his cock when she laughed. Sadly those marvelous things made Meyra groan in discomfort after a while.
"Damn I'm sore and stretched. My pussy really needs a break."
She lifted herself up, and with a wet sucking sound Roban lost his part of heaven, at least that's what it felt like to him. His sad look made the girls laugh again.
"Don't cry, I'm sure Chalissa wants to take a ride too. This time you'll even be allowed to cum!" With an evil grin she added, "But don't cum too soon, let her cum first. Promise me!"
Of course Roban promised.
Chalissa was even tighter than Meyra. She let him play with her tits right from the start. He figured out quickly that he could squeeze her tits pretty hard and she still would enjoy it, but pinching or pulling her nipples was less pleasant for her. When she told him to suck her nipples he was back in heaven. He sucked and licked like a starving animal at his mother's teats. Chalissa's climax was different from Meyra's. Her eyes lost their focus and rolled back in her head. Her mouth opened to scream but no sound came out. Her pussy muscles fluttered around his cock in random pattern of contractions all over its length. After a few moments of that she suddenly took in a huge gulp of air and the earlier missing scream came out with vengeance. Finally she just flopped over lifeless onto Roban's chest.
A few minutes later a tired looking Chalissa opened her eyes again and watched him.
"OK, your time to cum. I hope you can make it quick, my pussy feels like I've been staked on a tree for a week."
She tried to ride him as before but collapsed on his chest after a few minutes.
"I'm fucked out; you have to be on top. Please be careful, I'm also no virgin. The wall you feel at your cock is the end of the tunnel. You can't go all in, please don't try to," she told him panting,
Roban liked being on top. After a few moments of careful pushes he slowly pushed harder and faster without any complaints from Chalissa. To the contrary, her moaning and grunting turned up immensely the more forceful his movements became. She even urged him on with a litany of crude curses.
"Dammit, fuck me you brute ... Split me open ... Ram your cock through my womb ... Fuck the shit out of me ... Fuck me to death!"
It was like music to his ears. She came again before he wanted to himself. He simply enjoyed fucking her too much to end it. Again the silent scream, but this time when her pussy started fluttering he let go too. Now she really screamed, but suddenly the scream cut off and Chalissa went totally limp. And stayed limp, even after he pulled out, cum running in a thick stream out of her stretched hole and her pussy kept contracting for a few minutes longer. A bit worried Roban looked at Chalissa's unconscious body, but she was obviously alive. Meyra merely shrugged.
"Fucked out it seems. I've never heard her scream like that before. Your cock was probably a bit much for her pussy, at least the second go was. I could use a rest too. Wanna cuddle a bit before we sleep?" She asked him smiling.
Of course he wanted! Actually he wasn't tired but cuddling sounded nice. He had only ever cuddled with his little sister. The problem was, the moment he spooned Meyra's back, she pushed her ass in his groin and he became hard and horny again. Playing with her tits didn't help that one bit. Still, maybe an hour later, Roban finally dozed off.
He awoke to the whispering of the girls.
"So what do we tell Leandris?" Chalissa asked.
