Saturday night, we had a dance party.
My eighteen-year-old sister wore a low-cut dress, showing off her bulging boobs, and sexy stockings with lines in the back... Lines that went all the way up to the candy store.
Tabby drank wine and danced with all my buddies.
Wiggling her tits, flashing her thighs as she gyrated to the beat. She loved flirting with these college guys.
The music changed to a slow ballad. My sister took turns dancing close to every dude. Cheek to cheek, hip to hip. And I saw their cock lumps rubbing against her mound. Sis rubbed back while pressing her tits to their chests.
After more drinking and dancing, Tabby plopped on the sofa. "I'm too tipsy to dance." Sis kicked off her shoes and reached under her skirt, lifting it slightly as she rolled down a stocking.
Lifting her other leg, we all got a peek at her sheer panties as she pulled the second stocking off her foot. She noticed our stares. "Sorry guys, I just wanted to get comfortable."
A guy whistled. "Tabby, we love watching you get comfortable. Feel free to take off ALL your clothes."
"No. You boys behave. I'm going to bed."
I yelled. "Sis, can I come up and tuck you in?"
"Okay Troy, but no one else." Tabby led me to the bedroom and I helped her undress, paying particular attention to her tits and nips.
"Brother, I'm too tired to screw."
"But you gave me a raging boner. Be a good sister and bend over for a quickie."
"Okay boner boy." She leaned over, dropping her panties. "Here's my fuck-hole, hurry!" Tabby moaned as my cock pressed against her wet cleft and punched in.
Grabbing her tits, I screwed Tabby with long slow strokes. We heard someone in the bathroom. Sis looked back. "Fuck me faster but keep quiet."
"Yes, your tight pussy feels so good." We screwed with the muffled sounds of moans and pants. I thrust harder as her twat grew hotter. Soon, sis tensed up, covering her mouth as she climaxed.
Her spasming cunt sent me over the edge. My prick erupted, shooting out wads of cum. Tabby whimpered. Clenching her pussy muscles around my dick, she milked out every drop of jism..
Sis collapsed on the bed. "Thanks, brother. Thanks for tucking me into bed. You always tuck me so damn hard!"

I woke up with a hangover, so I had a Bloody Mary for breakfast. After a shower, I went looking for my sexy sister...with my boner leading the way. Tabby was in her bathroom. I knocked on the door. "Sis, I need to see you. It's really important."
"Okay Troy, wait a minute." The door opened and Tabby stepped out entirely naked. She saw me standing in the doorway with my boner sticking out, stiff and throbbing.
"Oh, that looks really important. Come on bro, let's make it another quickie!"
Tabby walked to the bed and lay on the edge, leaving her feet on the floor. I moved between her thighs, spreading her pussy lips with my cock.
"You wanted to fuck my friends last night, didn't you Sis?"
"No Troy, I was just flirting. I'm a terrible flirt. Did that make you jealous?"
"Actually it turned me on. I got hard knowing all those guys wanted to screw you."
My sister moaned as I pumped my prick inside her. "Oh Troy, last week you accused me of sleeping with your buddies...and now the idea arouses you?"
Squeezing my sister's tits, I shoved all the way into her cunt, fucking faster.
"Yes, it's like a voyeur thing." Tabby giggled. "Sis, last night I overheard Darren and Raul talking about sneaking upstairs and screwing your brains out!"
Suddenly my dick throbbed and spewed. Sis climaxed at the same time, crushing my cock with her convulsing pussy. I fell on the bed beside her, and we cuddled. She kissed my ear.
"Brother, what did you think about your friends talking about me that way?"
"I liked it Tabby. I actually fantasized about it last night."
