"Mmmmmmmmmmmmmmm."
My sister Gina enjoys me playing with her boobs. Very much so. At home, on a date... yeah, we date... or at work, like now. She's a nurse. A very sexy one. I decided to pay her a visit at the sperm bank she works at. Oh yeah... she works at a sperm bank. Visit my sis, fool around... and make a donation. A really cool way to spend an hour or so.
She's sitting in my lap in one of the "donation" rooms, her back to me. I'm groping those all natty 36Ds through her baby blue nurse scrubs top, really getting rough with them. Squeezing them extra hard, and kneading them deep and extra dirty with my big horny hands. Which in turn, is making my sexy, older, nurse sis writhe excitedly on my ever-hardening crotch, and moan really nice and slutty, while I do it all.
I'm licking and biting Gina's neck, sucking on it too, as I paw those big, beautiful titties, now doing it under her top, but over her dark blue sports bra.
"Mmmmmmmmmmmm. God, yes! Do it, baby. Paw the shit out of my tits. God, yes!"
Gina's very content smile makes me smile while I do my naughty shit. Manhandling those super soft melons extra rough through that tightly packed, blue sports bra. Her raging hard nipples tingling non-stop through the thin bra and onto the palms of my hands. My hands pawing and kneading them harder and rougher by the second, much to Gina's very appreciative delight.
Gina's wide butt slowly, but oh so perfectly, grinding on my bulge through my black leather pants. I'm going commando... and so is she... so her slutty butt is really going to town, working my fat veiny rod, rocking magically back and forth, and all the way around on it, over and over and over. And God... it feels fucking amazing.
Both of our bodies very much enjoying all of the very heated action in that sterile, sperm depository. The fact that we're making-out in a sperm bank not only turning me on so very much, but also my sister. Her nipples are threatening to rip right through that super smooth, blue sports bra any fucking second now.
My hands finally find their merry way up under her bra. Her warm, super soft, naked breasts exciting them so fucking much. I squeeze those big titties so hard. Gina screams out ecstatically with a big, wicked grin. She licks all around her pink lip gloss covered lips, grinding my now rock-hard bulge even faster with her big, thick ass.
I quickly reach down, and pull down her scrubs... and whip out my hard cock, which isn't easy to do in those tight pants... letting her naked booty do it's naughty thing on my exposed crotch. Awesome shit right there. Fucking awesome. My cock twitches non-stop. Throbbing and jumping against Gina's big booty as it heatedly glides across my big dick in every direction possible.
I move my hands back up to Gina's titties, pawing those bare boobs mercilessly. Really rough. Really deep. Shaking, kneading, squeezing, cupping, and slapping, then violently squeezing them some more. Gina's big jiggly tits turning red from all of the intensely furious titty manhandling.
Her nipples throbbing violently in my hands. Her loud and heated moans of joy echoing out in the room. Both of us laughing and grinning away from the naughty aspect of what we're doing at my sister's workplace.
"God... I wanna suck that big beautiful cock now. I just have to, baby bro. Mmmmmmmmmmmm." Gina sucks softly on her lower lip, grinning so bright and so wildly horny.
"Be my guest, sexy sis. But... be ready to swallow a whole bunch of it. I've got tons of sperm saved up for you, you filthy cum slut." We share a nice, naughty laugh at that.
A minute later, Gina's on her knees in front of the chair, spitting all over my insanely hard dick. Jerking it fast, rubbing in her spit lube, then spitting on it some more. I sit back, watch, and grin. My sexy bitch sister can work a dick like nobody's business.
Her shoulder-length, dirty blonde hair swaying slightly around as she wildly gobbles up my fat, veiny meat. Throwing her head around heatedly as she sucks me off. Her glossy lips stretched wide to very happily accept it into her cock starved mouth. Spit rolling down my meaty shaft. The big veins running all over my cock throbbing outta control as my older sister applies extra tight sucking pressure on my shaft. Her hands softly tickling and massaging my big, beefy balls.
Gina's big tits are hanging so enticingly out of her bra. Looking so wickedly beautiful. Her scrubs top still pulled up above them, just like her sports bra.
My happy growls are getting louder as more of my cock gets eaten up by my sister. Her head bobbing fast. Her glossy pink lips rippling up and down my shaft. The veins on it bulging. Thumping harder and harder as my impending cum gets closer and closer to becoming a very messy reality. I cum a lot... and my sister absolutely loves every fucking drop. Anywhere on her... or in her. She's not even worried about getting a specimen cup for me. She's gonna take the first load right down her fucking throat, like a true cocksucking slut.
Gina's sexy eyes lock onto mine. Her lips dancing faster down my shaft. That's it.
"FUCK!!!"
