As Lewis' struggles cease you feel satisfaction knowing he is already submitting to you but you are far from done. You were going to destroy every bit of pride your brother had.
You lift yourself up a bit. Still sitting on one of his arms you lifted your leg up and firmly planted your foot over his other arm, holding in place while giving you free use of both your arms. In a slow, exaggerated motion - mockingly - you lift your shirt up and over your head and toss it to the side. Despite your shirt being soaked your were still sweating from intense workout earlier in the day, combined with the 90 degree weather. Lewis immediately starts to struggle again but you shift your weight back down on him and grab his other arm again, reassuming the optimal position over him.
"Wow, Lewis. Your face is red." you laugh. "You're looking pretty heated. Don't worry though, I've got enough sweat to cool down the both of us."
"Ash, sto--!" before he can finish your brother's face is now in your sweaty bare armpits. As he continues to try and speak you quickly open and close your armpit, squeezing his face and making a suction/fart sound off of it that both shuts him up and cracks you up. Again Lewis' struggles subside just a bit - only enough so that he isn't rubbing his face into your armpit more by doing so. Realizing this, with his face directly in the center of your pit you slide yourself back and forth over him. This pulls his face up and down the length of your pits. Up and down, up and down, back and forth. After maybe just a minute you can feel it becoming easier as his entire face becomes slick with your sweat. After about 5 minutes his face starts to become uncomfortable with more friction as you've literally rubbed every bit of sweat into his skin.
"I see ya got that breakout all cleared up. Don't worry - I'm pretty sure I'm great for your skin." you taunt as you take his wrist in your other hand and shift over to your other armpit.
Lewis starts to scream but is once again muffled as you squeeze him into a headlock; face first into your hairy, sweaty armpit.
"shh, shh... relax......" you whisper into his ear. "isn't this just the best?" you continue is a hush, condescending voice. "They say smell is the strongest sense. We're makin' lasting memories here."
You open your pit again and resume sliding it round and round his face. "I feel like we're really bonding right now!" you laugh. "Can't say I didn't give my lil' bro the attention he needed." Lewis manages to shout off a broken up "I ha-- ---ou" but starts coughing and spitting a bit as ends up getting one of your hairs in his mouth.
"Ahaha, nice one, bro." you tease "I hadn't even thought of that, yet. Do I taste as good I smell?"
You continue to massage his face with your armpit but now concentrate on a smaller area, right over his mouth and nose - hoping he'll try and talk and end up with a mouthful of your pit hair. Lewis catches on and keeps his mouth shout tight but is now forced to breathe through his nose. Realizing this, you push the fleshy, most damp part in the center right up against his nostrils. Lewis struggles more intensely but you hold him tight. As he breathes in you can both feel his nose sucking and pulling against your pit and hear a slurping sound as he snorts your sweat directly up his nostrils. After about 5 long seconds you let him have air and he starts shaking and coughing.
Your brother has literally snorted your sweat right from your pits up his nose! You laugh hysterically "Ohh man! Hahah, good job lil buddy!" you notice how he's still shaking, making funny little tremors. "Ahah, easy there, bud. Wow, I must be like a drug, huh??"
Lewis finally catches his breath a bit and cries out "Ewwwww. I HATE you! It's dripping back.... down my throat... it's gross I can....tast--" still coughing "it's so...nasty...taste.... is so -<cough> strong."
"That's 'cause I'm strong" you sneer. "That's my power you taste! -- and the smell is submission."
"Don't you worry, bro, It might take a bit of work but we can get rid of that smell." you say in a comforting and reassuring tone. "... we'll just need to replace it with another smell, that's all!".
Lewis starts trying to yell - still hacking and coughing - and struggles more intensely so you throw one leg over his side and saddle him in a full mount while you decide what to do next; grinning and pinching his nose shut when he tries to blow out some of the sweat he inhaled.
