It was twisted, it was wrong, and it was so undeniably hot.
Tyler searched your face as you struggled with the idea, and then he beamed when you nodded reluctantly.
"Okay... Okay, I'll help you. But remember! You're really strong now, and you could hurt me real easily. Just be gentle, okay? And you can't ever-"
Tyler interrupted you, reaching over and pulling you closer. "I know I know I know, I can't ever tell anyone. I'll keep it a secret!"
You were close enough now that you could feel the heat from his muscle-bound body, and could feel the smoothness of his skin where your feet were touching his legs.
You took a deep breath to steady yourself, and then grabbed hold of his cock before you could talk yourself out of it.
He gasped at the contact, and spurted a jet of pre that was more voluminous than any load you had ever shot.
You opened your mouth and slowly moved to the tip of his cock, and began licking the tip.
This earned you another gasp, and a small whimper as he let out a spurt that make you cough.
"Are you okay, Joe?" He asked quickly, looking concerned and rubbed your back.
"Yeah, yeah I'm fine..." You assured him, and then wrapped both arms around his two-foot cock and began licking his cock-tip in earnest.
He bit his bottom lip and whimpered again, trying to keep himself from choking you with another spurt, and rested his big hand on the top of your head.
Relaxing a little now that he was being careful, you began to rub your hands up and down his shaft.
Tyler groaned, closing his eyes and bowing his head as he endured pleasure like he'd never known before.
"Joe...!" Your little brother had touched himself once or twice, but it hadn't been anything like this. This was incredible! His big brother was sucking his big dick, and he looked so cute while he was being submissive...
Then you stopping licking his slit and moved down to nuzzle his balls, squeezing and rolling them with your hands, and Tyler shuddered. This was even better!
When you looked up again, licking your lips to clean the pre off of them, Tyler reached down and pulled you up to chest-level with him.
He'd never intentionally harm you, but all the hormones were making him horny and dominant.
"Joe, I want you to..."
