Johnny grinned wide, smirking even more than before when Sammie put up no fight letting his cock slip between those soft, wet lips. So easy. He flashed Clarissa a little grin of approval. "Good<em>girl</em>" Johnny couldn't have emphasised that word more, now that Sam's cock was out. Johnny could feel the urge to taunt and feminise Sam rising up. For the first few moments he laid back to let Sammie show just how much of a good girl she was. And he was impressed as it seemed Clarissa's little brother was just as adept at this as she was.<br/><br/>He wrapped an arm around Clarissa, pulling her close and using one hand to guide her head, pulling her lips towards his mouth. He gave a hungry kiss, a little more like the commanding and forceful ones he had given Sammie as his mouth invaded the princess's mouth. Then she started her teasing questions. Johnny was only too happy to play along with that game. "Sammie's mouth was made for sucking cock. Wasn't it?" He asked, wanting to hear Sammie admit to that after hearing what Sammie thought of his cock.<br/><br/>Then Johnny turned from taunting Sam to looking Clarissa up and down. He felt a sense of indecisiveness. For a moment the urge to feel himself inside Clarissa was near overwhelming. But he had all night here, playing with the twins. And more time too, he was sure. There was no way he could fuck these two just once. So instead he decided he wanted to make sure Sammie was taught her place properly. When he saw how Clarissa was patiently waiting for him to take control Johnny decided to do just that.<br/><br/>"Here's the rules." He said with a confident grin. There was no sense of suggestion, just a command and explanation of what was going to happen. "Sammie gets to have her<em>tiny little... thing</em>stroked by Clarissa. But only when her pretty little lips are kissing the base of my cock." It served a few purposes. He wanted Clarissa to help tease and bully Sammie, and to be on his side. And he wanted to make sure Sammie only felt good while she was being a slut. This way she'd be stuck associating feeling good with having her throat full of his cock.<br/><br/>To facilitate the little game Johnny adjusted himself on the couch. He sat side, on, letting Sammie kneel on the couch between his legs while guiding Clarissa to sit up against his though on the space behind him. Sammie's access to his cock would be completely unobstructed, while Johnny's arm around Clarissa could help keep her nice and seated on the fortunately spacious couch while she could reach to force Sammie's head down or to tease him if she wanted to, and to kiss Johnny when he demanded it. And, importantly, Johnny got to watch as the boy he'd always suspected would be a slut did what he was best at.
