That night before I went to bed I carefully examined myself. Now that I was no longer a virgin I was sure that something must have altered me 'down below' so I got a mirror and sat on my bed. I looked at my lips β they seemed slightly puffy and swollen but otherwise looked normal. I parted them and examined the interior, then slowly inserted a finger and probed but could not discern anything different. What was all that fuss about virginity? The actions of my finger soon brought that familiar rush of moisture and I found myself sliding my finger in and out, mimicking the lovely thrusting I had experienced with Michael's penis surging inside me. But my finger was a feeble substitute, less than half the length of Michael's rampant organ, and pathetically narrow in comparison. I lay on my bed a while, my hand working energetically between my thighs, but the sensations did not thrill me even though I was intensely aroused. I read a book for a while and waited until my parents were asleep and the house was silent and then tiptoed to Michael's room. The dear boy was fast asleep. I crept in beside him and he woke up.
"Ssshhh," I placed a finger on his lips, "Michael, I can't sleep."
He pulled me close to him and took me in his arms. We kissed softly and I snuggled my face into his shoulder. "Michael, I have been thinking about today."
"Jen, you're not sorry we did it, are you?"
"No, Michael, of course not. But... Well, you came, but I didn't... and now I can't sleep."
Although it was dark I knew he was grinning at me. I punched him gently on his chest. He grabbed my wrist and pushed me onto my back, pinning me down.
"What are you proposing?" he asked.
"Well," I whispered, "I just thought... maybe you could help me..."
"Jen, we can't do that here!"
He released my arm.
"No, I know that, but you could β do this..."
I took his hand and guided it downward. I was only wearing a small T shirt and had nothing on below. I parted my legs and his fingers cupped reassuringly over my eager mound. Immediately I felt him swelling and growing hard against my hip. I left his hand between my legs and reached for him, found the slit in his pyjamas and wrapped my fingers softly around his erection. My brother moaned and kissed me, and his fingers started to work their magic. His touch was far more exciting than my own earlier manipulations. Our tongues touched, caressed, and we kissed slowly and sensuously as we silently pleasured each other. Michael's finger dipped inside, instantly generating shivers that rippled through me. I gasped and lifted my hips up towards him, aching to feel his penis inside me instead of his finger. I felt the solid girth of it filling my grasp, and remembered the feeling I had experienced as he had pushed it into me earlier that day. Michael's finger slipped out, wet with my juices, and his fingertip moved up, teasing the swollen bud. I moaned with pleasure and lay back, spreading my legs wider, and luxuriated in the delight as he skilfully brought me closer and closer to ecstasy. I tried to keep my hand moving on him but it was hard to concentrate and I gave up and cupped my breasts, squeezing them as the thrill grew and grew.
"Michael β Michael!"
"Ssssshh," he whispered, and his fingertip moved faster. I struggled to keep quiet as my orgasm burst and my body shuddered in delicious spasms. My legs clamped together, trapping his hand as I came. When the thrill subsided I kissed him.
"That was heavenly, Michael. Thank you."
"Do you think you will be able to sleep now?"
"I am sure I will."
"Well," he said. "You might be able to, but look at me!"
He drew the duvet back and in the dim light I could see him holding his penis at the base, pointing it up to the ceiling. It looked fiercely erect!
"Well, you can take care of that," I laughed and pretended to start getting out of his bed.
He grabbed me and pulled me back.
"Oh, no you don't!"
He put his hand on the back of my neck, and pushed my head firmly towards his erection. My goodness, Michael had never been so bold before! I felt a perverse thrill at being dominated.
"Michael, you will have to tell me what you want."
"You know," he said and urged my head down with another push. I reached behind me and took his hand away.
"Maybe I do, and maybe I don't," I teased him. "Either way, you are going to have to tell me what you want".
"Jen, you know what I want. Please do it?"
Oh dear, my darling brother was getting shy again.
"Michael," I giggled, "tell me, I won't do it unless you tell me. Spell it out".
He paused.
"Jen, I want you to... I want you to kiss it."
I bent my head and gave his penis a quick peck on the tip.
"There, done!" I said.
"No, Jen, I mean..."
I could sense my brother's anguish. On the one hand he was as randy as could be and desperately wanted to come, but he was by nature so shy and well mannered that he found it difficult to keep pace with his naughty sister.
"Jen, I want you to... suck my cock".
At last!
"Michael, why didn't you say so!"
I snuggled down in the bed and laid my cheek on his stomach and took hold of him, lifting him up from his stomach so I could get him to my mouth. I kissed and licked the very tip, catching the bead of moisture, tasting his saltiness, feeling him tense beneath me. I could smell him, that strange animal smell. It must have been the influence of his male pheremones because I always got instantly wet when I smelled it. I nuzzled against the firm rubbery glans.
"Michael, tell me again what you want?"
I think my brother finally understood that I wanted him to be forceful, because I felt his hand on my head, pushing me down.
"I want you to suck my cock!"
It was a thrill to hear him talking dirty and I obediently enveloped his glans in my mouth and suckled on him for a while before I broke away.
"Yes, Master, is that OK?"
Michael started to get into the spirit of it.
