“Harder! Destroy this tiny little pussy that you claim to love to fuck so much,” my wife yelped as I continued to thrust inside her, parting her glistening lips from behind. I love fucking her doggystyle. I looked down at her plump caramel colored ass and smacked her right cheek as I bucked my hips harder, plunging my manhood deeper into her sex. After the smack, and the redness it left, I grabbed her just above her hips and pulled her into me as I thrusted even harder. I looked down at the kaleidoscope of nerve endings just a few inches above my cock. Her forbidden entrance was the sexiest I had seen, and not forbidden at all. But I wouldn’t be fucking her ass tonight.
“Fuck you are sexy,” I groaned as I continued to manhandle her petite frame. Her girly sounds coupled with the clenching of the tightest cunt I have ever been inside made me want to explode. But not yet. My mind wandered as she screamed when I smacked her ass again. And then again. I went back a few hours to our date. A fun little night out with her sister and boyfriend. Drinks, appetizers, and bowling. Maria, her sister, took the ball in her hands and studied the lane. Her heels together with long legs protruding from the red and white shoes. Her legs were sexier than her sister’s. Long, lean, and young. Very young. She took three steps toward the pins, bent down and released the ball. My eyes stared at her nineteen-year-old ass as her much-too-short skirt flared up. She twirled around as all ten pins fell and leaped into the air. Her perky teen tits bounced in her blouse. But her ass. Fucking hell.
I smacked my wife’s ass again and looked down, imagining it to be Maria. I love fucking my wife, but her sister is fucking hot. It doesn’t hurt that she’s nearly a decade younger. I wonder if her boyfriend Michael is fucking her as I fuck her sister right now. SMACK.
“Fuck baby!” my wife moaned. “What’s gotten into you?”
I snap out of it. “Sorry, fuck, I’m just into it.”
“Don’t be,” she mouthed back with a pant. “Fuck me harder. Hit me harder. Use my body. I’m fucking loving it.”
Our sex life is great, but when images of her sister get into my head while I’m fucking her, I go into another dimension. SMACK. I slap her again. And again. I look down at that perfect little figure that I get to fuck whenever I want and all I can think about is fucking her teenage sister. I pull her hair back causing her body to rise as I penetrate at a different angle.
“God yes, I’m so close to cumming all over your cock,” my wife moans. “Don’t you dare fucking stop.”
“Mmmm,” I groan. “I feel you dripping all over me.”
I pushed farther inside her. The whole time I was fucking my wife all I could think about was how I wanted to annihilate her sister’s innocent pussy. No way her barely twenty-something boyfriend knows how to handler her. He’s way too timid to give her a proper fucking. I bet her nipples are pinker than my wife’s. Her skin is slightly lighter. Thinking of Maria’s nipples being hard and whether or not she keeps her pussy trimmed or waxed smooth like my wife’s sends me over the edge. I wanted to pull out and shoot ropes of white all over my wife’s pretty face. I love facials, and so does she. But the vividness of her sister’s innocent hot teen body along with the Asian death-grip her pussy had on my cock made me explode. Instead of on her face, I filled my wife’s pussy and made it overflow. It was the most I had came since, well, since the last time I thought of her sister while fucking her. Which, to be honest, wasn’t that long ago. Except the time, three nights ago, that I held my wife’s head while her lips were wrapped around my cock. I came so hard that it dripped from the crevices of her lips with my cock still filling her mouth. Droplets of white escaped her chin and fell onto her tits. I pushed her back onto the bed. She giggled, put a finger on her nipple and moved it up her rounded flesh taking a bit of my cum with it. She smiled, winked, and licked it off her finger. It was fucking hot. What was even hotter is that I imagined it was her sister. Goddamn.
“Holy fuck,” Nenita panted. “That was fucking hot!”
I pulled out and watched my cum seep from her insides. “Yes, it was,” I whispered to my wife while collapsing on my back beside her. Her breasts hung down as she was still on all fours. Her nipples could cut glass. My wife, Nenita, is sexy as fuck. She has always turned me on, more than anyone, except now that her sister was of age, it was hard not to imagine what it would be like to fuck her. And being her fitness trainer increased the sexual tension exponentially, at least on my end. Maria was much too innocent, and I think that is why I wanted her so badly. I just had one of the best sex sessions of my life, and all I could think of was what Maria would wear to our workout session tomorrow. Whatever it is, it will turn me on. Thinking of her in a sports bra and tight gym shorts made me hard again. My wife noticed, wrapped her lips around my member and sucked me until I filled her mouth. It didn’t take long.
“Someone was felling very frisky tonight,” she smiled and opened her mouth showing me that it was all gone.
“You’re a naughty little devil, aren’t you?”
“Gotta keep my man happy so he doesn’t stray,” she winked and curled up beside me. We feel asleep naked, spooning. I dreamt of her sister that night.
