Sister becomes my nurse

This is a fictional story, with two completely new characters instead of me and my sister.

Summer break is the best. Kids out playing basketball, or staying inside playing videos games till your eyes bleed. Me, I enjoyed skateboarding. One day I tried going down a set of 8 stairs and let’s just say… that was idiotic. I ended up with 2 broken wrists. God fucking dammit. My summer break and I gotta spend it doing pretty much nothing. It was kinda embarrassing at first because I could barely do anything myself. My fingers weren’t gonna get their strength back for like 2 months. So, in turn my family had to help me out. “Family” being my parents and my sister. But my parents worked long and hard and had other obligations outside of work, even during the summer. So my primary caregiver ended up being my sister.

The worst thing was I couldn’t masturbate. The days kept going on and my sexual frustration kept piling. What do you expect from a 15 yr old boy? I could only get so far by using my exposed but immobile fingertips. It was hopeless. As I already said, my sister – older than me by 2 years at 17 – became my main caregiver. She would help me undo my pants so I could go to the toilet and help me dress/undress in the mornings and before/after a shower. It kept getting more and more awkward as I couldn’t stop my boners every time my sister would help me. By the 8th day of summer, I couldn’t control myself anymore and my cock said “I’m in charge now.” I apologized to my little sister as she would have to lift my shorts back up and tuck my fully erect penis back into my shorts after the toilet. My precum would get on her hands and it was just a sticky mess. Being older than me, I’m pretty sure she knew all there was to know about boys dicks. I’ve caught her watching porn before in the past.

Don’t get me started on when she had to dry me off after a shower. She may as well have been giving me a handjob, yet she was so delicate as the towel grazed my balls and my taint. By day 12, I literally thought my balls were going to explode. My erections were almost purple. The light tug from the towel as she dried my hard, throbbing shaft was all it took; I sprayed cum all over her face. The biggest ruined cum blast I’ve ever experienced. Thick white ropes of cum came spewing from my cock. I couldn’t stop cumming for almost 35 seconds. As I looked down at my little sister’s cum covered face, she was calm and just kneeling there on the floor. “OH MY GOD. Madison, I am so sorry. I haven’t masturbated in 12 days and I was so fucking horny. PLEASE don’t tell mom or dad!”

She wiped a bit of the cum from her eyes and calmly said, “Its not the first time I’ve had cum on my face.” I was in disbelief as she grabbed a towel and walked into my room cleaning her face. I walked into my room behind her and as she started helping me put my boxers on, I asked her what she meant about not the first time having cum on her face before.

“Aiden, you might not want to hear this from me but I’m sexually active. I have been since I was 14. I’ve seen cocks and I’ve had sex. So when you came all over my face, that was nothing new. I mean… you ARE my brother and I’m helping you out ‘cause I knew I would have to. And I know it’s gotta suck not being able to pleasure yourself. But if you can keep it a secret and be nice to me… I can “help” you out with this till you recover. Deal? Because we aren’t gonna be playing Spider-Man every time I dry your dick off. I’ll jerk you off or whatever I gotta do to get you to cum. This stays between us because I’m probably the best damn sister on the planet.”

Since that day I didn’t know what to think but apparently my cock knew. So getting out of the shower the next day with a raging hardon, about to burst, my sister got the message immediately. She grabbed some lotion and started slowly stroking my shaft with her soft hands. She definitely had some experience here; playing with the tip of my cock, pulling my foreskin, caressing my balls, changing the strength of her grip, and more. She stroked harder and faster and as she saw I was about to cum she aimed my cock right at her mouth. But instead of just opening up, she took my cock in her mouth and tightly sealed her lips. I guess she didn’t wanna make a mess so I just let go and spewed all my hot cum into her wet, warm teenage mouth, which she swallowed a moment later.

Later that night she came into my room again. She was wearing a loose fitting top that showed her nipples through her shirt. “So bro how was the handjob earlier today? Did I do I do a good job? You don’t need to answer that; the amount of jizz that came out speaks for itself.”
“You have no idea how good it felt, Mads. I thought afterwards I would regret it because you’re my sister and I wouldn’t see you the same way. I thought it would be all awkward between us now, but I don’t feel anything different.”
“If I’m being completely honest, Aiden… I’m kinda happy you broke your wrists. ‘Cause now I get to see your cock every day! Let me say that you have a very nice cock. And your big saggy balls are so lickable too. I don’t mean to sound weird and I don’t know where it came from but… I’ve been into incest porn for a while. It’s just what gets me off nowadays. More than any other genre. I’m sorry, but I figured this is the best chance I can get to share with my brother.”
“Wow, Maddy. I mean, I could tell when you swallowed my cum and you didn’t flinch that you enjoyed it, but I didn’t know about your incest kink.” Just that once sentence did me in again. I was getting a hard on. I couldn’t help it. I looked down at my boner and then back at Madison. "Well, sis… I guess I need some ‘help’ right now, if you’re up for it.”

I stood up and the tent in my pants was staring my sister in the face. She proceeded to pull my boxers down to reveal my rock hard cock. With no hands she opened her mouth and started giving me a blowjob. She was going very slow, and I could tell she was savoring the moment. She took my cock out and slapped it against her face. She pushed me on the bed where she started licking my balls. I couldn’t believe the pleasure I was experiencing. This blowjob was becoming sloppy as she wasn’t swallowing any saliva or pre cum. Then out of nowhere she started deepthroating my cock. Just up and down and up and down. I had no idea she had these skills. I was in pure ecstasy as the cum was sticking to her lips as she would pull away to take a breath. My throbbing cock felt like it was going to burst if it got any harder.

“Cum in my mouth, Aiden, whenever you’re ready. I want you to shoot that hot cumblast down my throat.” I still couldn’t believe this was happening. She went back to deepthroating my cock. Up and down then she would pause once she had my whole cock in her throat and wiggling her tongue all around my cock, savoring all the precum that was in her mouth.
“I’m about to cum!” “In my mouth, bro! I want every last drop!”
She was sucking faster and harder up and down my cock like her life depended on it. I couldn’t hold it any longer. I went of like a firehouse in her mouth. My legs trembled with every pulse of my dick, filling my sister’s mouth with my hot, sticky cum. Even after emptying my balls for the second time that day, it was still one of my biggest cums. She pulled away from my cock to open her mouth and show me the amount of cum I shot. She was swirling it around in her mouth. I couldn’t see any of her teeth or her tongue. It took her 2 gulps to empty her mouth of my baby batter. “That was so amazing, Mads. Its gonna take days to replenish the cum I just shot into your mouth.”

“That is the most cum I’ve ever had in my mouth. I’m glad my big brother could do that for me. I love having your cum in my mouth, Aiden, it tastes so good.”
“Well… looks like my balls are gonna be empty for a long time from now on, eh?”
“You know it. And I’ll make sure they stay empty, big brother.”
