“Would you like me to help provide some relief? I know I’m your sister, but I can make the discomfort go away.”
His breathing was shallow, desperate. I could see the desire in his eyes. “Yes, please.”
“Good boy.” I grasped the base of his shaft, pointing his dick towards me and then enveloped his large head into my mouth.
“Oh, fuck,” he hissed. He drew in a breath between his teeth as my lips closed over his shaft. I swirled my tongue around the head, making his body squirm with pleasure.
“Oh, God, sis..!”
I loved sucking cock. Especially one with a large head like this one. The fact that it was attached to my little brother only made it all the more exciting.
Many men I had pleasured orally considered me a world-class cocksucker.
I applied more suction to his crown and then let my lips slide down over the head and onto the shaft. I groaned inwardly as I tasted the salty-sweet precum on my tongue.
“Can you keep your mouth shut?” I asked him.
“Huh? Y-yes, of course.”
“Good. Then I feel better doing this.”
I took his tip into my mouth and began to slide it down my throat. It almost felt like a python devouring its prey. I giggled to myself, watching his face. Poor Billy didn’t know what to make of his own sister taking his entire cock down my throat.
I backed off a little and slowed down when I felt him reaching his limit again. I wanted to enjoy the moment for as long as possible. Professionally speaking, it also facilitates the maximum amount of ejaculation, thus speeding up his recovery.
Billy was thick, one of the thicker men I had the pleasure of sucking off. As a challenge of sorts, I took his cock right down to the balls, almost making me gag in the process.I was so proud of myself when my nose brushed against his pubic bush.
Then I started bobbing my head up and down, using my throat muscles to milk his gorgeous cock.
His hands gripped the sides of the table. “T-Tina… Oh fuck..!”
Urged on by his desperation, I put him out of his misery. Young men really had no patience. I would need to spend plenty of time training him. I supposed inexperience had its allure, too.
Billy cried out as his cock swelled in my throat. With a desperate, needful grunt, each spurt shot down my throat as his cock pulsed uncontrollably, and his body bucked and writhed in unadulterated ecstasy.
Then something happened to me.
The act of pleasuring my little brother had a profound effect on me, too. So I reached down and teased my pussy, in an attempt to alleviate some of the pent up frustration. But it had the opposite effect. It felt too damn good having my brother’s thick cock down my throat. It made me hyper sensitive. Every stroke of my finger over my clit sent waves of pleasure through me. His cock swelling in my mouth, dumping load after load of hot, thick cum in me, pushed me over the edge and I came hard. The world turned white, and I tried to focus, greedily swallowing as much of his cum as possible.
I was impressed by his vigor. Despite cumming so much earlier from my ‘massage’, it seemed like he still had plenty stored up.
When he was done, I let his cock slip off from my mouth and I opened wide, showing him his cum before I swallowed. I wanted him to remember this as the best sex experience of his life.
“You have one of the nicest penises I ever had the pleasure of sucking,” I said.
“Thanks, sis.”
I enjoyed jacking him and sucking him off, and true to his claim, his cock was still rock hard.
That all too familiar need, that craving, grew inside me. I needed his big cock inside me.
I was curious to see what my brother’s cock would feel like stretching me out.
Semen dribbled out from his tip, so I leaned over and licked it clean. His cock slid into my mouth again and I let my tongue roll over the crown, licking and sucking on him gently to clean it up.
“Billy, I think we need more drastic measures. Clearly, your penis is still not satiated, so I feel compelled to do everything in my power to help you.”
“What do you have in mind?”
I got off the examination table and removed my clothes.
I had a great amount of pleasure watching him eye up my body. I didn’t know any man who could resist the allure of my big breasts, womanly curves and tight pussy.
I hope Billy was curious to find out about the last bit.
“Would you like to have intercourse with me? Of course, everything we do will be bound by patient-doctor confidentiality, so don’t worry about anyone finding out about this.”
“Damn, I’d love to, if it’s okay with you, sis.”
I smiled and climbed back onto the table and gave him a few minutes’ worth of cock sucking.
No longer able to ignore the ache deep inside me, I straddled him, grabbing his shaft and aiming his dick directly towards the entrance of my pussy.
“I’m going to have to control the penetration. A cock as fine and big as yours might hurt me if you get too enthusiastic.
He nodded, and I held the lips of my pussy open with one hand. With my other hand, I guided his cock to my opening.
I dropped my hips ever so slightly until my pussy kissed his tip.
It started going in, but then it stopped.
Fuck, he was a big boy.
I licked my lips. It felt divine, but I might be too tight for him.
I was determined to take him inside me, though. I rocked my hips up and down, each movement taking a little more of him. I hissed at the sharp bite of pain, his bulbous head stretching my opening. I didn’t care. I needed to feel him in me.
I thrusted down as hard as I could, and maybe I took in half of his shaft.
“Oh, fuck, sis. You’re so tight..!” he husked.
“You’re so nice and big inside me, Billy,” I moaned, feeling my thighs buck from the strain and sweat beading down my forehead.
I bounced up and down, making small strokes. As the discomfort mellowed over, I let each stroke go a little deeper. Luckily, I was so turned on from having such a big cock, I was soaking wet with need. My juices helped with lubricating him.
I braced my hands against his hard abdominal muscles. A few more strokes later, my pussy kissed the root of his cock.
“Finally,” I sighed with satisfaction.
I was in heaven. I told him I was going to start moving, and I moved my hips up and down, my pussy milking his cock with each delirious stroke. He was so thick and deep inside me, it was like a mixture of pain and pleasure.
I hissed through my teeth, enjoying the feeling.
“Sis, can I touch you?” Billy asked. His eyes were fixated on my breasts.
“Of course. Apart from nourishing, breasts are also used to enhance the sexual experience. Touch me as you please.
My brother swallowed and reached out, taking each breast in his hands. They were more than a handful for him, and I felt my nipples harden against his touch.
I sensed a tinge of reluctance in him. Some remnants of shyness still bubbled inside him.
I clasped my hands over his as I rocked, tightening my pussy around his cock, and milked him. I guided his hands until his fingertips brushed over my nipples.
“Yes, that’s it,” I cooed. “Don’t be afraid to explore. Play with them. I will let you know if you do anything I don’t like. Communication is key.”
