Sam knew that his sister knew that he wasn't going to answer her question. It was a trick question! She'd taught him this long ago. You never answer any question with a cock in your mouth. Sluts know what their mouths are good for after all! Sam reminded himself of this as he shot a playful glance to Clarissa as if to say 'nuh uh, you're not getting me that easy!' He was a bit curious as to what Johnny would say to his question though. Him and Clarissa had a running joke about who was the better cocksucker. That and kissing were the two things that were fair to compete in. Some men had preferred Clarissa. Some had preferred Sam. Most had said both were amazing and then given whatever answer they thought would give them another blowjob fastest. What would Johnny say, he wondered idly as he reached about a third of the way down and paused there. He put his own hands around the base of it again, not moving them just using them to hold it still.<br/><br/>Johnny's comment though, also got no answer, although the response was more of a pouty glare than a playful look. It still stung Sam in a way to hear Johnny say such things about him! He could still remember Johnny making similar comments at school, shoving him up against lockers and asking him if his black gothic lipstick made sucking dick easier. Well, he didn't dress like a goth anymore. He still wore lipstick. And no, it actually didn't! Still, he glanced away quickly, not moving his head off the cock. Clarissa would scold him if he did. And then he would feel bad. No, once a cock is in your mouth it only comes out if the dick is about to go in someplace else.<br/><br/>He paused as Johnny announced that there were rules. More rules? He gulped, the feeling tangible to Johnny, as he referred to Sam's cock as a tiny little thing, the female pronoun almost obviously meant as an insult there! He glanced down at Johnny's dick. There was no way. He'd never get this all the way down! He'd never got a cock this big down his throat! Maybe halfway at best!<br/><br/>Still, his need to have his own cock played with was so powerful. It was throbbing, dripping a little even, it really really really wanted his sister's soft touch! He made an upset, whimpering noise into Johnny's cock that would be felt as a rather nice buzz, and then glanced down again. Mmmmf! He had to try. It was almost pointless but he had to try.<br/><br/>He forced his head down. It slipped a little. A half an inch. Another half inch. His throat was being moved aside. He knew he couldn't go much further. He slowed down. A little more. A little more. A little more.<br/><br/>Suddenly Sam was choking, his throat shaking and quiver all about Johnny's sensitive cock head. He pulled back quickly, inhaling sharply through his nostrils, a bit of drool slipping out around the cock itself. His eyes got a little red and watery from that. He glanced up, begging with his tearful eyes to change the rules. He could see Johnny had no such intentions. And so he steeled his nerves and threw himself down that dick again. Again he choked, but this time he held it there for a bit longer, about two thirds of the way down now. Not that far away!<br/><br/>He did it again, and again, choking on Johnny's dick and pulling back to breathe. He knew from experience sucking dick that most guys told him this felt amazing and it was so hot seeing someone choke on their cock. But he knew despite this that he wasn't going to be able to get all the way down. And so he pouted and sucked the big dick in his mouth and hoped it would just give him a new blast to choke on so that he could let it go and play with himself at least!
