He took my advice to heart, and I felt him relax. I moaned as he tugged and fondled my nipples.
I leaned forward, letting my tits droop over his face. Billy understood and took a nipple into his mouth and sucked on it.
“Yes, that’s it,” I groaned, rocking my hips back and forth, feeling his length rake my insides. “Suckle on them, little brother.”
Billy grunted, and I felt his energy change. His tongue lashed against my nipple and he started moving, his hips meeting my thrusts.
He wanted to lead.
I smiled and let him take over, let him drive his cock up into my cunt. “Fuck me as hard as you can.”
He groaned around my nipple, sucking on it a little too hard, sending a sharp bolt of pain through me.
I didn’t mind though, finding his newfound enthusiasm intoxicating. I cradled his head with the crook of my arm, whispering into his ear. “That’s it, fuck me. I want you to cum in me, okay? Give it all to me, little brother. Fill me up.”
His face went tight, and I knew he was at his limit. Like a woman possessed, I bounced back against his movements, taking him as deep in me as possible.
I knew it was going to end, so I wanted to make the most of it.
“Sis, I’m going to cum. I’m cumming!” he yelped.
Sweat slicked between our bodies as I pressed myself tight against him, pushing my mouth onto his lips. He groaned and my tongue snaked in, finding him. He mumbled something into my mouth, and his hands clawed my buttocks, holding me tight against him.
I cried out, letting another orgasm wash over me as I felt his cock swell in my pussy. He held me tight against him, not letting me go as he emptied his cum deep into me.
God, I took it willingly, savouring the sensation of hot, potent cum flooding my womb as my body shuddered with orgasmic pleasure.
His hips kept rocking, as his body tried to force as much of his life force into me, driven by the one singular need to inseminate me.
If I wasn’t on contraception, I would surely be impregnated by a young buck like him.
We lay there together, spend and exhausted for a moment.
I slowly got off him and his cock slid out of me, leaving me a gaping mess with globs of cum leaking out of me.
I hopped off the table, and with a sudden flash of mischievousness, I bent over and took his flaccid cock in my mouth and sucked our juices off.
“Fuck,” he shuddered.
He was definitely a good fuck.
Then, rather unceremoniously, we both got dressed.
“We made good progress today,” I said, giving him my assessment. “Considering the amount of times you can ejaculate before you are done, I think many women will find that a plus in a sexual relationship. Your size may be of a concern, but you will have to find a partner who is understanding of that – not all women like big penises.”
He nodded.
“I recommend finding a steady partner. That would be the most efficient way to keep your libido levels in check. Until then, your sister will be more than adequate.”
I made him an appointment for a follow up assessment, and I was already looking forward to feeling my brother’s hard cock inside me again.
