Get on your knees between his legs

The sight of your little brother's bulge is too much as you kneel down in between his legs. He stops his gaming and watches you with wide eyes as you lean down placing your nose onto his bulge taking in his musk. You quietly groan from the smell and place your warm hands on top his legs letting it slowly massage its way up to his thighs.

"Adam! What the fuck are you doing bro?" you hear his friend shouts through the headset. His concentration is on you now as you rub his inner thigh under his shorts while your finger tips occasionally grazes his hairy balls. You look up see Adam watching you intensely as you continue to tease him as he has tease you.
