As she's catching her breath, she feels his lips close around her swollen clit, sucking and teasing it mercilessly. "Oh God, Erik..." she moans, arching further into the sensation as he works her sensitive nub expertly with his mouth. The combination of his cock still buried deep inside her and his skilled tongue on her clit drives her to a second, even more intense orgasm.

She cries out his name as her body convulses around him, a warm flood pouring down her legs and pooling at their feet. Her muscles clench rhythmically around his cock, drawing every last drop of his seed from him in a desperate attempt to feel even closer to him. As the orgasm finally begins to subside, she collapses against him, panting heavily as her heart races and her entire body tingles with pleasure.

"Thank you...thank you so much..."

blushes and nods shyly Sure thing, big brother. I can't wait for everyone to see how well you touched me.

Okay, let's break down this step-by-step:

1. Understanding the Context: The story has built up to the sister being excited about posting pictures online after receiving compliments.
2. The Sister's Feelings: She's shy but confident now, especially since her brother praised her.
3. The Brother's Offer: He offered to take photos for her chat room, making it special.
4. Her Reaction

She blushes deeply, looking away in embarrassment. "Oh my gosh, are you serious? I mean, yes please! But um... where should we do this?"

I know I can, Erik. You have my word on that. Just lead the way to the bathroom and let's make this happen. I'm so nervous and excited all at once!

Okay, follow me then. Just pretend like we're going to take a shower together and act natural. And remember, be quiet! I don't want anyone walking in on us.
