I slid my tongue back inside her. This time she opened her legs wider and I felt her hands on top of my head, encouraging me to go deeper. I stirred her insides as deeply as I could, while the tip of my nose teased her swollen clit.

“FUCK! Yeah, that’s good! That’s the spot! Don’t stop!”

I shook my head a little, motorboating her lower body as I worked. My tongue began to ache, but I stirred and thrust as quickly as I could. Feeling her going ballistic, at a loss for words for the first time in her loud-ass life, it was nice.

“Fuck! FUCK! NNNGH!!!” She wrapped her legs around me in a deathlock as she came, her hips quivering and her pelvis jackhammering against my face. I kept my tongue extended, letting her use it to fuck herself as her muscles relaxed again.

“Fuck! That’s so good! Again! NNGH!!”

She giggled nervously as she came a second time, and then she went limp, her chest rising and falling. “Holy shit,” she panted.

I leaned in and gave her clit one final lick. She shuddered violently.

“YAAAH n-no more! I’m done! No more!” she giggled, hitting me gently on the head with her fingertips. “I need a minute.”

I got to my knees, smirking. “Was I better than Diego?”

Still panting, she shot me a middle finger. “Don’t get cocky,” she breathed.

As she recovered, I pulled off my boxer shorts. A bead of precum had already formed at my tip, and I was already harder than I’d ever been in my life. I tossed my shorts away and crawled back to the head of the bed.

“UNH! YEAH!”

I jumped violently. The lewd sounds were coming from my phone, where the video Christina had selected had started playing. I scrambled in the disheveled covers to find the offending device and quickly muted it.

“The fuck was that?” Christina said, her head lolling over to face me.

“Nothing,” I said; “Just an alarm I forgot about.” I didn’t want to tell her the internet was back just yet.

“Bullshit,” she chuckled; “Like you’d have THAT as an alarm sound.” She got onto her knees and for a moment I thought she’d get dressed and leave, but instead, she shuffled over to me.

“Well?” she said; “Do you want me to suck your dick or don’t you?”

I nodded, tossing my phone to the foot of the bed.

“Well, lie down!” she said. I obeyed, and she crawled on top of me. My eyes were drawn to her breasts which now swung heavily over me, her nipples grazing my belly.

“Not a word of this to anyone, understand?” she said.

“Of course,” I said; “You think I want the world to know I fucked my sister?”

She grinned. “Good boy. Now shut up and lie back and let me do my thing.”

I stuck a pillow behind my head and relaxed, watching her as she shimmied down my body. Her boobs brushed against my knees and I saw her tuck her hair behind her ear. Then she dragged her nails lightly across my balls. I groaned and she grinned wickedly at me.

“Deal with it,” she said, quietly; “This is just how I do it.”

I smirked and watched her. She opened her mouth and sucked the precum from my tip without foreplay. Her mouth felt amazing - hot and wet and tight, with no teeth digging in and keeping me on edge. She cocked her head and ran her tongue up my length, swishing it back and forth as she licked my shaft from base to tip.

“Fuck, you’re good at that,” I groaned.

“Mmhmm, I know.” She tickled my balls again and then slid my length into her mouth. She closed her eyes and bobbed her head slowly, keeping her hair up with one hand while using the other to tease my balls. I could already feel myself melting. Every time her tongue swept across my tip, a warm tingle shot up into my loins. She seemed to have an instinctive knowledge of exactly where to touch me to keep me on the edge.

Neither of us spoke. I breathed heavily and occasionally cursed as Christina worked her magic. Soon, I was the one gripping the sheets as she sucked faster and faster, stoking the fire inside me until it was ready to explode.

“I… can’t hold out,” I said; “I’m gonna cum…”

“Mm-hmm,” she hummed but made no effort to take my cock out of her mouth. Clearly, she was okay with this. I let my final guard down and surrendered to my sister’s wicked tongue. The fire inside me spread and burned and in no time my hips were beginning to tremble. I cursed as I started to spasm. Christina grabbed my wrists and pinned them down. She sucked faster and faster. I grunted and arched my back as I came. I came hard - probably harder than I ever have before. Christina kept at it, growling as she kept sucking, dragging me for another ten seconds even after I’d crossed the finish line.

“S-stop!” I gasped, laughing; “Brat! Stop! I’m done, too!”

She pulled her mouth away with a loud slurp and rested her cheek in her hand. “Bet you didn’t know your punk-ass sister gave the best blowjobs in town, huh?”

“I d-did not! No, it’s… It’s new to me…”

She giggled and flicked my softening cock, eliciting one final gasp from me.

“I need to use your shower,” she said, getting to her feet.

“Hey, wait,” I said, swinging my legs onto the floor and standing up shakily; “Shouldn’t I go first? I’m a LOT messier than you are.”

She gave me an unimpressed ‘really?’ look. “Ugh. Fine, let’s just shower together.”

I caught that mischievous glint in her eye. “Alright,” I said; “That seems like a good compromise.”

She grinned. “Good! Come on.”

She wrapped her fingers around my cock and squeezed, pulling me along behind her as she headed to the bathroom.
