Helping My Sister

I have an older sister Lora, one year older than me. She is a senior in high school. She is one of the very popular girls in school, but she does have some problems when it comes to studying. Honestly, she is incredibly hot! I am her brother, and I will freely admit that I think she is hot and I have plenty of jackoff fantasies about her. Lora is blonde, blue eyes, 5’6″ great figure. I have seen her many, many times in her bikini and I can say she has a great ass and big tits, big nipples when they become erect. I have some pictures of her in her bikini that I use to jerk off to daily.

She came into my room one day to ask me to help her.

“Blake, I need to ask a favor of you.”

“Sure sis, what do you need?” Luckily for me, I was sitting at my desk. Otherwise, she would have seen the erection I got while talking to her.

“I am doing really badly in one class, and I need help to study for the mid-term. If I fail the class I will have to take summer school before I can graduate. I desparately need you to help me.”

“Sure Lora, I can help you study.” She ran up to me with her arms wide open. She gave me a huge hug, pressing her tits against my body, and gave me a quick kiss on my lips. “Thank you so much! You are an awesome brother! If you can get me to pass, I will owe you big time!” She turned and left my room; I watched her sexy ass wiggle as she walked out of my room. Seeing that was all the encouragement I needed as I got up, grabbed one of her pictures and cranked one off.

I helped her study for her midterm, and she ended up getting an ‘A’ on her test. I will never forget when she showed me her grade. I was up in my room playing with PS4; she came running into my room, “Look Blake! Look what I got on the midterm you helped me study for!” She got an ‘A,’ and I was so proud of her. Thank you, thank you, thank you so much, Blake!” She jumped on my lap and gave me several hot, thank you kisses all over my face. I felt a bit embarrassed.

“Oh come on Lora…quit it.” She stopped kissing me, with her arms still around my neck. She was straddling my cock; I hoped she could not feel my hard-on. She looked at me,

“Oh, you like it, Blake. I know you like having me cover you with kisses.” She gave me a little wink, and as she did, she brushed her knee across my cock as she got off of me.

“Well Blake, I still want to thank you for your help.” I laughed a little at her.

“I thought you just did?” Lora didn’t say a word in response, she just smiled at me, and she got this odd look on her face. Lora placed her hands on my knees, spreading my legs apart; as she did it, she dropped down to her knees. “Um…Lora…what are you doing?” She didn’t respond at all as she moved closer between my legs. Then she reached out, grabbed my belt, slowly undoing it. I jumped up in my chair; I never expected this from my sister. She kept looking up into my eyes, smiling with her beautiful smile. Lora then unzipped my pants and placed her hand on my erect cock! The electric sensation that shot through my body as my sister touched my cock was incredible. I honestly thought Lora was going to give me a hand job; I didn’t expect her to suck my cock instead!

“I can see you really enjoyed me kissing you!” Lora said as she slowly stroked my cock. Before I could think of something to say, she lowered her lips to my prick head and gave it a wet kiss. Then I watched as my cock slid into my sisters’ mouth! I let out a loud moan, and then I yelled out

“Oooh Fuck!” as Lora slowly slid my prick out of her mouth. My sister smiled at me, giggled a little as she ran her tongue all over my throbbing shaft and then licked the pre-cum from my cock head. I couldn’t keep my eyes off of my sister as she licked my cock. She got my cock so wet with her saliva as she ran her tongue all over my cock before running her lips up and down my shaft. I never had a blowjob before, and I knew no blowjob would ever come close to being as good as the one Lora was giving me.

Lora then licked my balls, sucking them lightly into her mouth, working her tongue around them before releasing them from her wet mouth. I kept my hands on arms of the chair, trying to keep myself from writhing around with such lustful pleasure as my sister now fully sucked on my cock. Then it hit me; this was incest! I knew why it was considered forbidden; it felt so fucking great! I kept watching my sister bobbing her head up and down my hard prick. The slurping sounds coming from my sisters’ mouth as her wet lips worked my shaft made me even hornier. I could feel my sister sucking my pre-cum right out of my prick. My eyes glazed over as I lost myself in this erotic pleasure, I just watched and listened to my sister sucking my cock. I couldn’t believe how great a blowjob felt and how great my sister was at giving head. I have watched so many porno movies, and I never saw a blowjob as hot as the one my sister was giving me!

She really knew how to suck a cock! I lost track of time as I watched her working her lips up and down my cock. As she worked my hard prick in and out of her mouth, she kept rubbing my balls. I could feel my cum load building up in my erect shaft. I suddenly realized that I didn’t ask her if I could cum in her mouth or not. At this point I was so lost in my lust I was not going to stop my sister to ask her. I just figured I would let her know I was going to cum and see what she would do or say. I kept my arms resting on the arms of my chair as I looked down at Lora and she kept looking up at me as she worked my prick with her sweet, wet mouth.

“Oh Lora…that’s it, please don’t stop sucking my cock. Oh yes, Lora…I’m gonna cum! I can feel it Lora…I’m going to cum…sis…I can’t…I can’t hold it much more…I’m going to come!”

She didn’t stop; she didn’t say a word; she just worked my cock faster and faster moving her mouth up and down it. The pressure kept building as I tried to keep myself from cumming in her mouth but I the intense pleasure I was experiencing would not allow me to hold back for too long. Finally, I couldn’t hold back any longer, I grunted and yelled out, “FUCK! I’M CUMMING!” At that moment my prick exploded inside of her mouth. All the times I have jacked off, I have never come as much as I did in Lora’s mouth; that includes all times I have jacked off to her photos.

I felt my cock pumping spurt after spurt after spurt of my hot cum into her mouth and best of all was I could feel Lora swallowing it! I don’t think she was expecting the amount of cum I spewed from my cock because I could feel her gag at one point from the volume I unloaded into her mouth. I was in such a delightful world of pleasure, not just from cumming but from knowing how much cum I was pumping into my sister’s mouth; I cum a lot! Lora kept working her mouth up and down my prick as filled her mouth with cum; cum was now working its way out of her mouth. I saw my cum running down the sides of her mouth and her chin. I gave her a wicked grin as I watched her trying to keep up with my volume. Finally, I emptied my prick into her mouth. I felt her swallow several more times as she sucked my prick dry.
