My Sister Helped me with My Boner.

I want you to tell you of something that happened to me that if I told you I'm sure no one would believe.
I was in my twenties and visiting my parents, My parents were both in their fifties, mom was still in great shape for her age and I know she looked after herself.
They had arranged for us to go out for a meal that evening so we all had to be ready for a curtain time.
As I was on my own in my bedroom I was feeling rather frustrated I decided to have a good jerk off, but for some reason, I couldn't get it hard, maybe the trip down of the medication I was taking affected my bloody cock.
So in my infinite wisdom, I had some enhancing tablets so to speak.
Popping a few I waited for the reaction to take place.
Sure enough within twenty minutes, I had one hell of a hard-on, laying on my bed I started to pump my now mega-hard cock, hoping to finally relieve the frustration I had felt all afternoon.
Still, it wouldn't happen, I just couldn't get to the point of shooting cum, it wouldn't happen.
The thing was time was moving on and it wouldn't go down, The stories of these tablets giving you a long-lasting hard-on on this occasion were true.
Then out of the blue Mom knocked at my door, You getting in the shower soon we have to be ready to go in a few hours.
In my very nervous voice, I shouted back, “Okay Mom no problem,”
“You okay, you sound funny,” she said.
“Yeah, I'm fine, just working on something that's all,”
“ okay whatever it is hurry up okay,” she said.
The thing was it wouldn't go down, my bloody cock was so hard that I was worried if I couldn't cum I would have one hell of a bulge in my trousers all night.
After about twenty minutes of trying things were getting a bit worrying, nothing was happening, Then my slightly younger sister knocked at the door and just walked in, Holding a basket of washing she said,” Mom told me to bring you this,”
“Don't you ever knock, “ I shouted.
Then looking straight at me she said, “You jerking off when you should be in the shower,” she said.
“Look leave me alone okay, Yes I'm bloody jerking off,” I said.
“ moms going to kill you if you're not ready, you know they can get mad if we piss them off,”
“Don't you think I know that, look close the door,” I said.
“What's the matter with you,”
“Look I took a pill Okay now it won't go down,” I said.
“ you daft sod, what you going to do,”
“ that's it I don't know, I'm stuck”. I said.
Well, I don't want any arguments tonight okay, I'm actually looking forward to it,”
“ I know me too but it's not going to look good is it with me having this bloody bulge in my pants,” I said.
“Okay look do you want my help,”
“What? How the hell can you help with this,”. I said.
“Look you have a problem, Do you want my help or not,” she reiterated.
“Okay how”
Back in five minutes,” she said.
Still, while she was gone I kept trying to sort this mess out, still, it was so hard it hurt, then my sister came back, saying for all our sake this better work okay,”
“What will,” I asked.
“Look I'm your sister you my brother, We help each other right,”
“Yes, why what are you thinking,”
“If I do this you will owe me big time,” she said.
With that she grabbed my sheet covering my cock,” What you doing,”
Then leaning forward she took my shaft and proceeded to suck my cock, I couldn't believe what she was doing, her mouth just seem to devour my whole throbbing cock.
“ Christ is, what the hell,”
Looking up she just said” You want to cum don't you, so shut the fuck up and let me sort this,”
With that, I laid back and let her try to get me to cum.
After ten minutes of sucking me off, she realised it wasn't happening,
“ Jesus how many tablets you took,” she asked.
“Two,” I said.
“You suppose to only take one you stupid idiot,” she said.
“So what now,” I said.
“Okay plan two, now this is the last resort okay,”
Asking me to stand up she turned to me saying if this doesn't work your screwed ok,”
“Want doesn't work,” I said. Turning around she just dropped her panties saying,” fuck me, get that Cook in me and fuck me,”
“What, I can't You my sister, “
“Look it's the only way to sort this, If you don't then like Ive. Said you're screwed, it's your last option,” she said.
Looking down at my sister's backside and I must say an amazing-looking pussy, I just took my cock and slipped it into her wet hot hole.
I began to fuck my sister's pussy, she covered her face in my bed to drown out her moans as I just went for it, I pounded her pussy for all it was worth.
Holding her hips, I pulled my cock into her as far as I could, she then lifted her face saying, you best hurry up in going to bloody explored in a minute at this rate, my cock continued to thrust deep into her, then I could feel my cum begin to rise up my shaft, she too just screamed in my sheets, I could hear her muffled noises and I groaned as my cum was about to blow, pulling out I held my cock and shot my cum over her back.
I splattered her with so much cum that she said, “After that lot, I'm showering first okay, and you owe me big time.”
Nodding I said “Thank you and you have an amazing pussy for my sister,” I said.
“ yeah well that's the biggest cock I've had in a while as well,” she said.
“ Shame your my sister you're a great fuck,” I said.
“ shame your my brother, or I would fuck that cock of yours most days,”.
“Okay well if I can return the favour if you feel you need relief then let me know,” I said.
“You never know I think I might take you up on that offer,” she said as she left my room.
The evening went as expected, all was calm with us after my cock issue, then when we got home we all made our way to our rooms, as I lay on my bed my phone flashed up a message.
My sister said, “ I need help, I'm frustrated,”.
Replying I said,” Well if you need help I have the perfect cure,”
“Do you have the same issue as earlier, “
“No, but I'm sure I can get things moving so I can help you with your problem,”. I said.
The next thing was a quiet knock at my door, Letting my sister in she said.
“We have to be quietso mom and Dad don't hear us.”
“It's ok I can do quiet,”
“ I just need a quick again, since earlier my bloody pussys been on fire, all evening,”.
“Okay, I can do it quickie if it helps,” I said.
As she only had a robe on, she turned round as she did last time, lifting her robe up she again exposed her backside and pussy, “ Just slip it in will you am horny as hell I need to get sorted,”
“All I could do was do as she asked, I slid my cock into my sister and began to fuck her tight pussy once more.
“ you can cum inside me this time, I'm on the pills so it's ok” she whispered.
That just seem to spur me on, I slowly pounded her pussy as again her muffled groans just echoed around the room.
Within a few minutes, she came as my own orgasm pumped my cum into my sister's tight pussy.
She instinctively pushed back on my cock to get me in deep as I filled her with my load of cum.
When I had done she stood up saying, “Thank you I needed that, I Best get cleaned up before Mom and Dad see me.
With that she left my room, I couldn't believe we had sex again, twice in one day, and with my own sister.
After about ten minutes my phone went off again,
“ thank you for helping me my pussy and myself are now sorted for today, can we just stick to quickies, I don't think I'm ready for the full naked full-on love-making thing,” she said.
I was only at Mom and dad house for a few days but in that time my sister and I made the most of the quickies and I must say we became even closer after that weekend.
