She was moaning and groaning constantly now, and while one of her hands was busy gently cradling and massaging my swollen nuts, I saw her other hand dive down between her legs. This was typical for her, bringing herself off at the same time she sucked me off. It was the nature of our relationship, and we were both happy with it. We both got exactly what we wanted.
“That’s it, just a little more,” I said softly as I worked her mouth up and down on throbbing prick, “and you’ll get your first load of medicine.”
This brought another moan from deep in her throat, the lusty groan vibrating right through my cock and sending my libido soaring. My sister was a slobbery cocksucker, and this time was no exception. I could see her slippery spit oozing from the corners of her mouth as I moved her pursed lips up and down, slimy rivulets of hot saliva sliding erotically down the surface of my thrusting cock.
She moved her hand from my sack to the base of my cock, and then started to do that thing she does that always drives me crazy. She scratched gently at the taut skin around the base of my cock, her sharp fingernails leaving small pink trails on my skin. That teasing touch of hers never failed to have me climbing the walls in seconds flat. Between that and her hot tongue rolling all over the shaft of my throbbing dick, I was a goner. I felt the boiling semen in my nuts start to speed up the shaft of my cock.
“OH FUCK! I’M GONNA… I’M GONNA COME!” I warned as I started to go off. I felt my body flexing and shaking as the first thick rope of cum jettisoned forth, plastering itself against the tissues at the opening of her throat. I kept working her mouth up and down as I continued to go off, totally unloading shot after shot of hot, thick cum deep into her eagerly-sucking mouth.
“EHMMM!!!… EHMMM!!!”
I heard my sister let off that tell-tale squeal of hers that I’d come to know so well, letting me know her own fingers had brought her off at the same time I was flooding her mouth. But even when she was coming, she kept sucking like the hot little cocksucker she was. Her tongue and lips were working their magic on my cock as she drew out rope after rope of sizzling spunk. She was swallowing and swallowing, but still white trickles of jizz oozed from the corners of her stretched lips.
“OH FUCK… YES!” I said with guttural groan as I threw my head back and let the intense pleasure roll through me. When my sister sucked me off, it never failed to take me to the exquisite heights only that hot mouth of hers could reach. And, knowing how hungry she usually was, I knew we weren’t done for the night.
“As usual, that was fantastic,” I said as I started to come down from my orgasmic high.
My sister looked up at me, her eyes smiling as she kept gently sucking and nursing on the seeping tip of my cock, getting every drop of creamy seed out of me that she could. She finally slid her mouth off the end my dick, licking her lips salaciously.
“God, I love the taste of your cum, big brother,” she said. “But you’re still hard. Does that mean you’ve got more for me?” She looked at me with a teasing look in her eye as she drew one fingertip over the oozing red eye and then licked it clean.
“I think we both know the answer to that,” I said as I released my grip on her head. “How do you want the next one?”
“You know I love it when you fuck my face.”
I was only too happy to oblige. With a smile on my face, and my turgid cock still standing at attention, I slid out to the side and we switched spots. My sister was now propped up against the pillows with her back to the headboard. This was a position we’d been in many times, so I went right ahead and swung my leg over her lush curvy body, my knees resting on each side of the swells of her breasts. I looked down at the massive spheres, her braless tits settling nicely over the full breadth of her chest, her nipples hard as diamonds as they poked against the soft fabric of her t-shirt.
“Slow and easy, or good and hard?” I asked. I started to lever my hips forward as I wrapped my hand around my turgid dick and pointed it right at her face.
“Slow and easy for a little bit, and then give it to me with all you’ve got.”
She looked up at me and I could see the desire in her eyes.
“And you want me to blow this load all over your face, right?”
“Of course,” she replied, that mischievous look on her face as she formed her mouth into a nice wet target for me.
Not wanting to waste time, I flexed my hips forward and watched as my thick cock made those sweet lips spread wide, her jaw opening as far as it could as I slid right into her hot wet mouth.
“Mmm,” she purred again, and her eyes closed as she clamped down on my cock, her tongue starting to work its magic already.
With my surging prick firmly locked between her lips, I released my hand from around the shaft and reached up for the headboard, grasping it with both hands. With a firm grip there and my knees planted on each side of her, I started slowly rocking my hips, sliding my prick smoothly in and out of her pursed lips.
“Mmm…” she purred again as I got into a slow rhythm, working my cock back and forth as she got used to the thickness and length. I smiled as I looked down at her lips sucking at it, feeling her tongue against my cock as she really went to work. That’s one thing we both liked about her insistent use of the scrunchie; neither one of us wanted any stray hair to get in the way of that talented mouth of hers. Her hair was still pulled well back, securely anchored in that ponytail as I felt her hands come up and grasp the cheeks of my ass, pulling me forwards, letting me know she was ready for more.
It was nice that our mom and dad’s bedroom was at the opposite side of the house, because when I started to fuck her face harder, the headboard started to beat a steady tattoo on the wall. At first, we’d been afraid of being caught because of the noise but nothing had ever happened, and it had been many times since the first time that I’d fucked her face like this.
“Uhn… uhn… uhn…” I was giving off little grunts of pleasure now as I levered my midsection back and forth, sometimes throwing in a slow hip-roll so I felt the warm wet heat of her whole mouth. She was moaning and whimpering with bliss as I fucked her face good and hard, spit drooling from the corners of her mouth and dangling off the underside of my throttling cock to drop erotically on the swells of her breasts. I watched her hand shoot down between her legs again and could smell the intense warm scent of her pussy as I glanced over my shoulder to see her fingers working busily beneath her panties.
Not wanting to come right away, I eased back and slowed down, and then proceeded to ramp things up again as I fucked her face good and hard. She came twice while I was speeding up and then slowed down a couple of times, and then I couldn’t put it off any longer, her mouth was just too hot. I was flexing my hips like crazy and she was whimpering like a wild thing as I felt my climax start. Two more good hard thrusts were all I could stand before I drew back, pulled my surging dick right out of her mouth and quickly wrapped my hand around the bucking shaft.
