Sam's eyes were locked on Clarissa's, but she was looking at Johnny. It made him smile to see his sister so happy, and he felt tingling all over his pretty, feminine body as he leaned in and their lipstick touched. It was always so sweet when he pressed his lips against his sister's back to the very first time, and every time after that for the years that they had been slowly building up to where they were right now. So many of his first experiences had been with her, and then with her and a stranger, and now, now she finally had her prefect one and he could help pay her back for all she'd done for him! And all it would cost is his dignity and self-respect and well, all small prices to pay for Clarissa to be even half as happy as she'd made him!<br/><br/>As they kissed it was almost like he could forget whose cock she was stroking off right now. But then his hand gripped Sam's thick lustrous hair and he felt himself being pushed down with his sister. He knew she'd want to do this, so he didn't dare resist.<br/><br/>The thick head of the cock bumped into their chins and so he pulled his chin back just enough that it was now poking at their lips, even as their lips locked with each other. He relaxed he kiss for a moment to see what Clarissa would want to do - keep up the kiss in a teasing manner that just brushed at his cock, or do something more. Either way he told himself, whatever my sister wants, she gets. She deserves it!
