"We'll be back tomorrow night Max," said Max's father as he left; he and his wife were going to spend the night on the town.
Max's parents had left and the eighteen-year-old was now alone in the house. He quickly ran upstairs and changed. He grabbed a box from underneath his bed and headed back downstairs.
He sat in front of the television and opened the box. It contained several porn videos, all featuring women with usually big breasts. Max was obsessed with women that had big tits. He had never dated a girl with really big tits before. All the girls who were interested in him only had C cups. The ones with the D and double D's were too high class for him or fat.
Max popped in one of his videos, it was called "Julie's Juicy Jugs," into the VCR and sat back with some lotion and a towel.
As the video got more intense, Max pulled out his hard seven-inch cock and stroked it. A huge black cock was fucking Julie Jugs hard. Her huge fake breasts bounced and flopped unnaturally on her chest like huge silicon boobs do. The cameras zoomed in on her big tits; Max increased the speed of his stroking. He laid his head back and moaned as he reached his climax.
Suddenly, as Max's cock began unloading a river of hot cum, his older sister Brenda entered the house, dropping her suitcases as she saw him. Her eyes bugged out as she realised what she was seeing.
"MAX!!! Where are mom and dad?" Brenda blared.
"OH SHIT! BRENDA!" exclaimed a surprised Max, as he tried to hide his cum-spewing cock from his sister's sight with a pillow of the couch.
"That's disgusting Max," Brenda commented.
Max's face turned red as Julie Jugs reached her climax and came all over the huge black cock which was still pounding her pussy raw like a piece of meat. Her huge fake tits continued to bounce and wobble on her chest.
"What the hell are you watching?" Brenda asked.
Brenda saw Max's box full of big tit porn.
"I knew you were sick Max, but I didn't know you were this sick," Brenda said, as she picked up one of his busty pornos and read the box.
"Catch big-titied Shelly fuck like no tomorrow and watch her enormous plastic tits bounce like someone playing the bongos," Brenda read. 'Big fake tits Max? Haven't you ever seen real breasts before?"
Max straightened up and put his cock back into his PJ bottoms, still covered in his sticky ejaculate.
"Yes, but all my girlfriends have only had C cups, Brenda. A lot better then your chest," Max argued.
"Oh really?" Brenda said astonished by Max's statement. "Then I guess you have never seen F cup tits before?"
"F? You have got to be kidding me? There is no such thing as F's, unless you got implants. Don't tell me you came all the way from college just to show mom and dad your implants?" Max challenged.
"No, stupid brother, I don't have implants; mine are actually the real thing. Seems to me you haven't been paying attention much, I had a growth spurt a few years back," Brenda explained.
"Why would I want to look at my sister's chest?" Max asked curiously.
"Because your sister has, real, huge tits, the likes of which you've never seen before," Brenda responded.
Max focused his attention on Brenda's chest and saw large lumps underneath her heavy jacket.
"Take off the jacket and let's see?" Max suggested.
Max felt a tingle in his cock, as it struggled to come back to life.
"Ha ha ha, Silly brother. Be careful of what you wish for, you might just get it," Brenda uttered as she winked at Max.
Brenda started to unbutton her jacket. She tossed the heavy jacket to the floor. She had on thick sweater, full of different dark blues. Brenda's chest got Max's eyes, as her breasts looked larger without the jacket.
"I'll do you one better. I'll take off my sweater too," Brenda quipped.
Max started to sweat and moved around in his seat, as Brenda grabbed the bottom of her sweater and started toying with Max. She lifted her sweater up barring her shirt-clad stomach, then brought it back down. Brenda slowly started moving erotically like a stripper. The smell of Max's ejaculate covered cock arousing her. She teased Max a little bit more and finally lifted the sweater completely off her top-heavy torso.
Max's dick quickly hardened as he laid eyes on his sister's enormous rack. Brenda still had on a gray tee shirt, which was stretched outwards due to her massive tits. Her enlarged nipples poked through the thin gray shirt and bra.
"Now do you believe me?" Brenda asked teasingly as she giggled.
"How do I know your bra isn't stuffed?" Max suggested, as he rubbed his hard cock through his jeans.
"I'm not finished young brother," Brenda said, as she reached under her shirt and unfastened her mammoth bra. She pulled the huge bra from underneath her shirt and allowed her gigantic F's to sway and wobble freely underneath her shirt.
The swaying giants underneath his sister's thin gray shirt hypnotized Max's eyes. Her nipples massively poked through her shirt.
"God sis! You have such..." and before Max could finish, Brenda leaned over to him and slipped her juicy tongue into his mouth.
Max returned the favor and French kissed his sister. Her enormous udders hung down in front of Max's chest and lightly brushed up against him.
