My baby sister part 2

I sat there, dazed and recovering after getting the inexperienced-but amazing blowjob from my baby sister. She was on her knees in front of me, my cum dripping down her face and tits, still trying to catch her breath after I had fucked her face and filled her mouth with my jizz. I felt a mixture of guilt and satisfaction at that.
“Did you…Did you have an orgasm?”
“Yeah kid. I did.” I chuckled. I saw a flicker of some emotion on her face, and sat up.
“Do you want one?”
She kept her eyes downcast, embarrassed about what had happened, what was happening now, but she nodded all the same.
I quickly pulled off my shirt and used it to wipe my cum off her chest and face. Then I picked her up like a baby and lay her trembling form down on the couch.
“Just relax.” I whispered, stroking her stomach in gentle circular motions. She closed her eyes and took a deep breath, and I let my hand draw lazy circles up around her right breast, spiraling to the nipple at the center.
It hardened instantly when I took the tiny pink bud between my thumb and forefinger, rolling it gently, then giving it a light pinch. I leaned forward until my mouth hovered above her nipple, and exhaled, sending a shiver through her body.
Then I took it into my mouth, sucking, licking, biting her until she was gasping.
As I repeated the process with her left breast I slid my hand down her stomach, cupping the crotch of her jeans and massaging her pussy.
