Sis looked at the white fluid that I had deposited in her pussy, “Did you just cum in me?”
“I’m sorry, Sis,” I cringed, “I couldn’t help it.”
“It’s a damn good thing I’m on the pill,” she said, calmer than I expected.
My eyes roamed her body, stopping between her spread legs. I saw the cum dripping from her tight pussy. She rubbed her finger up and down the slick mess that I had made in her sex. My cock still stood, hard and throbbing.
She looked at me with a naughty smirk, “Do you want a sloppy second?”
“Fuck yes,” I said with enthusiasm.
Sis stood up and told me to sit on the shower bench. I followed her instruction, my cock pointing at the ceiling. Sis turned away and sat on my cock, guiding it in with a hand between her legs. She slid slowly down my shaft until her soft ass was on my legs.
My head fell back against the ceramic wall as she started rocking her hips, grinding her tight pussy on my throbbing cock. I could really get used to this.
Sis hung her head forward as she rode me. My hands steadied her firm hips. Her hands rested on her knees while she labored. I felt her start to tremble and she moaned loudly. Her orgasm was building. Slipping one hand around the front, I fingered her clitoris to help. She convulsed when she felt my fingers on her most sensitive spot.
My balls were already nasty with my cum from our previous fuck. It was a nasty good feeling. So hot and slippery. The only reason I had not already climaxed was the drip on my face from the showerhead.
“Fuck, little brother,” she growled, “Fuck me with your big cock.”
My free hand slid up her wet body, cupping her left breast. Her nipple bore into my palm. She was on the edge, all she needed was a push. I curled two fingers and took a chance. Sis was taken completely in the pleasure of an extreme orgasm when I pushed the two fingers inside her pussy along with my dick.
She was already slick from my cum along with her own juices, but her orgasm generated a flow of girl cum than flowed like a faucet. I felt it run over and down my forearm, dripping from my elbow. I had to remove my hand from her tit in order to cover her mouth. No need to wake the parents at this point. she wrapped her arms around herself and almost fell forward. I pulled my fingers from her pussy and caught her with my slippery hand.
I lowered her to the floor of the shower as she came hard. Kneeling between her legs, I pushed my cummy cock back into her. She had stopped screaming and was in the part of her orgasm that made her just float on a cloud. I started pounding my cock into my sister as she writhed under me. I could feel the heat in my groin growing, bringing me closer.
Sis was staring into my eyes and saw that my orgasm was imminent. She wrapped her legs around my waist and held my hips tightly to her ass. I was at the point of no return. Nothing short of an atomic bomb, or dad walking in could stop me.
I grunted and thrust one last, hard time. My cum erupted in a violent blast. I felt it pump through the length of my cock. Gritting my teeth in order to keep from shouting, I pushed my hips harder I to hers. Her fingers slid over my cheeks as she sweetly looked into my eyes. My orgasm past, I collapsed onto her body, breathless. she tickled the nerves of my back with her fingernails.
”This is going to be a fun summer,” Sis whispered into my ear.
The end
