[B/s] [Incest] [Blowjob] Sister Inspects My Cock

​

I ran into my house, my face red and flushed.

That’s it, I had enough of women, they’re all evil, cruel bitches.

I thumped my way past the living room and headed for the kitchen, I needed a drink, something to wash away the taste of shame that built up in my throat.

“Hey what’s wrong?” I heard someone call out from the living room. It was Julie, my sister. She was a couple years older than me but unlike other siblings, we got on like a house on fire.

“Nothing,” I called from the kitchen, rummaging for a carton of milk. I took a deep swig and enjoyed the distraction for a moment.

“I know that tone. You’re pissed about something. Come over here and we can talk about it.”

I sauntered to the living room, I felt the weight of the world on my shoulders. Julie was lounged on the sofa, the telly was on in the background. Textbooks were spread either side of her. She must’ve been studying as usual. She’s not the usual bookworm type of girl though. She wore glasses yes, but she had a hot librarian look about her. Sometimes I catch myself staring at her too long when she’s deep in thought, chewing the rubber end of a pencil. I catch myself wondering if her lips were as soft and sweet as they looked.

Today she was wearing and oversized sweater, and yoga pants. The sweater was comfortable looking, and did a good job of covering up her generous cleavage. The yoga pants though, did nothing to hide her round, peachy ass.

Christ, what the fuck am I doing? What is my problem?

I know what the problem was. I was horny as fuck. I was horny 15 minutes ago and I sure as hell am horny now, now that I had the chance to calm down.

“You ok?” Julie smiled, giving me that angelic smile that never failed to warm me up.

“Not really,” I moped.

“Come, sit. Tell your big sis all about it.” She patted the seat next to her.

I made a show of reluctantly crashing down next to her, but I couldn’t be more pleased. I loved that scent of lilac and jasmine she seemed to always carry with her.

“Girl problems?”

I nodded. Half the time, she knew the problem just by looking at me.

“I thought you were getting along great with what’s her name, Sally?”

“Yeah we were. Not anymore.”

“Bad date?”

“Yeah.”

She gave my leg a reassuring squeeze. A hum of excitement shot from where she touched me right to my cock. I tried to focus feeling guilty instead.

“How did you mess it up?” she teased.

“It was going great,” I sighed. “Just that after, when we got back to her place…”

“And?”

“We were fooling around.” A hot flush rushed up to my face. “We were kissing and shit and I was getting naked and she laughed at me.” The words tumbled out of me before I could stop myself.

Julie adjusted her glasses and cleared her throat. “She… Did not like what she saw?”

“She laughed at it. She said my dick was gross.”

“I see.”

We sat there for what seemed like an eternity. It was so quiet, I swore the sound of my heart beat was roaring in the room.

“Do you mind showing me?” Julie asked, clearing her throat.

“Show you..? My dick?”

“Yes.”

My stomach turned into knots. Sally, yes maybe. She was a date, a girl I hardly know. But Julie. Not Julie. I can’t do it. I can’t bear for her to laugh at me too.

“No way.”

“Don’t be afraid. C’mon, I’m your sister.”

She gave my leg another reassuring squeeze. “Besides, it might help with my bedside manner, me studying to be a doctor and all. I’m expected to not be phased over anything. And I’m sure my little brother is fine.” Then she hit me with that killer smile.

“Okay, sis,” I sighed.

I stood up. Deep down I’m freaking out, but fuck it. If I can’t trust Julie, then I can’t trust anyone. I fumbled the tongue out from the buckle and let my jeans drop to the floor. I closed my eyes and thumbed down my boxers.

“Oh my…” I heard Julie say after what seemed like forever.

“It’s fucked up isn’t it.”

Silence. I pried my eyes open, I needed to see her face, her beautiful, angelic face marred with horror. Instead, she was wide-eyed. And she seemed to be biting down on her lower lip.

“I-its… Fine. I haven’t seen a finer specimen before, if I do say so myself.”

“You’re just being nice.”

“I’m not! It’s a very delic- I mean, strong, sturdy looking cock.”

*Cock*. I never heard such words come out of my normally reserved sister. For such a filthy word to come from her lips. It was kinda hot.

“Maybe it’s weird looking when it’s, you know, hard.” I always thought my dick looked a bit different to other guys’. It wasn’t just longer than usual, it was fat too, like an overfed leech or something. I used to break out in cold sweats when I had a boner in class; there was absolutely no subtle way to hide it.

“I’m not sure myself, but that’s a good hypothesis. Do you think you can make it hard so I can be certain?”

Maybe I was imagining it, but her eyes almost had a hunger to them.

“Can you look away first?” I never jerked it before in front of someone else, definitely not in front of my own sister!

She gave a mischievous smirk and half turned her head away. I tried to not think about her being right there and gave the little guy a tug or two. Shit. It wasn’t working. Performance anxiety? I cursed to myself. It was a medical examination for God’s sake. I stroked, rubbed and tugged, but it was no use. My nerves were raw from embarrassment.

“I can’t do it.”

Julie turned back; her eyes fixated on my dick. “Nervous?”

“Very.”

“Hmm, maybe it’s because you feel like a lab rat. I know, how about if I took off some of my clothes too. It’s fair then and maybe you’ll feel like it’s an even playing field.”

I tried not to sound too excited. “Yeah that makes sense.”

Julie lifted her arms and pulled the bottom of her sweater and yanked it over her head. She wasn’t wearing anything under her sweater apart from a lacy white bra. I tried not gasp. Hell, I tried not to stare but her gloriously full and ample breasts were right there in front of me. I could almost but not quite make out the beautiful areolas half hidden under the lace too. A painful throb of excited twitched in my cock.

“Had a good look?” She teased.

“Sorry.” I felt the heat burn under my cheeks.

“It’s not fully erect yet.”

“I don’t think I can make it hard by myself. It didn’t work just then.”

Before I could complain, Julie’s hand shot out and grabbed my semi flaccid cock. “Maybe you need a helping hand.” She said, her tone thick with sensuality.

Her hand gently danced up and down my shaft. I never felt anything like it. My own hand didn’t feel this good.

“Go on little bro, get hard for me,” she whispered. I tried to suppress a groan. I didn’t know what to do with my hands so I clasped them behind me like a soldier standing to attention. I didn’t know where to look; either the heavy rising and falling of my sister’s breasts, or her face. She looked really, really hungry. For some reason her expression looked hotter than her chest area right now.

Her fingers wrapped around my rapidly hardening cock. Thick angry veins crawled along the shaft and a bead bulged right behind the nape of my cockhead. I felt her eyes fixated on it.

“Its weird isn’t it.” I said, trying to be professional, trying not to let the sensation of her silky soft hand drive me to the edge. It was so wrong to feel this way, that my own sister was jerking me off. Fuck, that thought made my cock twinge and a pearl of precum beaded out of the end.

“Not at all,” she breathed. Her words were slightly slurred, laborious. “From a biological standpoint, you have an amazing specimen of a penis. It’s so thick and so proud. The way it’s shaped, it’s designed to maximize pleasure and increase the chances of insemination.”

My cock never felt harder. The combination of her exquisite touch and her ‘proper’ science talk was an erotic contradiction.

Her face inched dangerously close to my dick. I could feel her breath almost but not quite grazing me. In some desperate hope, I entertained the fact that maybe, just maybe my sister would wrap her lips around it. If not that, then I needed to go away and rub it out. My cock was perilously close to breaking point and there was a very real danger of me ejaculating all over my sister’s face and ruining our relationship.

“Julie…” I moaned. “I’ll to cum if you keep doing that.”

“Really?” She squinted her eyes and her breath grew heavier. “Sorry, it’s my fault you’re like this. I should take responsibility.”

“Oh fuck!” I cried as the sensation of her warm, tight mouth enveloped me. Never in a million years would I ever expect my sister to suck me off right. Many nights I jerked off to her. Sometimes I would raid the dirty clothes basket and sniff her panties. But for this; my beautiful elegant sister to be doing this. I was unbelievable.

Her tongue swirled and lapped at me, I felt her trying to draw out my semen. My hands wrapped around the sides of her hair, tugging at her long, silken auburn hair. She moaned in response. Her fingers wrapped around my shaft but not quite enclosing it, gripping and pumping as fast as she could.

“Sis… you need to stop, I need to cum…” I begged, feeling that deep ache rising from my balls.

“Cum in my mouth, baby brother. I want to taste your cum.”

Oh god. That did it. Such filthy words spilling out and encouraging me. I can’t, I’m going to cum in my sister’s mouth!

With a hearty bellow, I clamped down on her face and submitted to my sweet, desperate release. Wave after wave of thick, hot cum spurted from deep within me and shot right into my sister’s waiting mouth.

Julie giggled with glee as the cum hit the back of her throat. I looked down at her and her eyes were wide with need and she didn’t stop pumping away, determined to coax as much cum out of me as possible. With one final spurt, I relaxed and collapsed onto the floor. Without thinking twice, my sister opened her mouth, showing me the copious amount of cum I’ve just unloaded into her.

She closed her mouth and took one big swallow, ingesting it all. Ingesting my cum. I groaned at the sight of her throat moving up and down, picturing all of my incestuous cum travelling down to her tummy.

“Yummy,” she simply said, letting my cock flop out of her mouth. “If you need more tests, you know where I am.” Then she stood up, used her thumb to scoop a drop of cum that was leaking from the side of her lips, ate it and walked upstairs.

I sat on the floor butt naked, panting and dumb founded at what just happened.
