Erica was home for the summer from her freshman year in college. Campus living was certainly a different experience, but she could wait to be home again...even if she was sharing the house with her geeky little brother. Their parents would be away for a month on business (both of them the corporate types), so the house was going to pretty much going be theirs.
Her younger brother Eric (their parents were very unoriginal) was when she left him about 10 months ago, a tall and lanky twig of an 18 year old. He wasn't a typical geek per se, but he was the most popular guy in school either, kind of a tweener with average looks. You could imagine her surprise when she got out of the cab and saw him at the door. He had really filled out.
"Oh my God, look at you!" she screamed as she greeted him with a hug. "What have you done with my little brother huh?"
"Made the football team," Eric answers. "Coach works us like dogs, you know?" The work had certainly paid off nicely. Gone was a tall, lanky kid and in his place was a well built young man, muscular, fit but not a powerlifter build, moreso like a Greek sculpture, the near perfect male form. He effortless grabbed up the bulk her bags and led her back into their home. It was just like they left it when she left, save for it being pretty quiet.
"How long have Mom & Dad been gone?" she asks.
"Couple of days. You know things are really kind of different around here now. Most of your old friends are either pregnant or just straight up bar tramps now."
"I'm sure it's not all that bad now is it?"
"You remember Tina, right? From next door? She's the town sperm bank if you catch my drift."
"Damn..." Erica replies. Tina was the girl next door...literally, straight A's, bright and cheery demeanor. "Guess a lot has changed...but some for the better, yourself included."
She smiles and he smiles back they reach her room.
"Still that same way you left it, a mess," Eric laughs. "Mom did straighten it up a bit, but she knew you'd flip out if she moved anything."
"Isn't that sweet...well, I guess I got some unpacking to do. What're you gonna be up to?" "Oh nothing, hit the mall maybe, chill out for a bit. Want me to get you anything while I'm out?"
"No, I'm just gonna relax." With that, Eric left. He was still as shy as ever it would seem. She fathomed whether or not he was still a virgin, and gorgeous as he looked now, because of his timid nature.Erica was now busy pulling out all the clothes she brought with her. Didn't take long before she was settled right back in, laying down on her bed in the big, empty house. "God, I can't do this...if I was gonna lay around in an empty building I'd have stayed on campus."
Erica grabbed her keys and headed on out herself. It would be good she thought to she just how much the place had changed for herself. She met up with a few friends, even Tina, who true enough was a whore who worked for free, flirting heavily with some guys at the bar they had went to. It was getting late, so Erica decided to head on back home. She was still a bit tipsy, but managed to get back safely, and entered the house quietly so as not to wake her brother who was probably asleep. Tip-toeing down the upstairs hall past her parents' room she could hear a wet slapping sound coming from Eric's. The lights were off so creeped over and open his door a crack not worried that she be noticed. The sight she beheld left her breathless. Eric was laid spread eagle on his bed, his completely naked body exposed for all to see assuming that he was home alone, stroking his cock.
His huge cock.
His hand was wrapped around the biggest member her eyes had ever seen, even bigger than the ones on the guys she saw in pornos she and friends giggled over in the dorm room. It had to be about a foot long from base to tip, and it was very thick. It was generously lubed as he masturbated to a magazine pictorial of a busty brunette, much like Erica herself. His body was glistening with sweat, indicating that he probably was at this for a while, his muscular, chiseled body gleaming in the nightlight he had on to the side.
Erica couldn't help but think that this whole scene was really hot. She stood there spellbound as her younger brother (whom she officially would have to stop calling "little" as of tonight) cranked on his monster. Her own hand wandered underneath her skirt, sliding her panties to the side as she started to play with herself watching it all.
This went on for a few more agonizing delightful minutes until Eric closed his eyes tight and groaned aloud. She had to bite her lip from doing the same, but then her jaw simply dropped. He let loose with vertical cannon shots of white goo that splashed all over his stomach and chest. He was quite the gusher.
Eric thought she was going to swoon. She quickly but quietly shut his door and rushed to her rush to her room before he noticed she had just watched him service his gargantuan tool. Throwing herself on her bed, she slid off her panties and began to brush at her clit with her dainty soft fingers. She began to masturbate furiously herself, stuffing her fingers into her pussy. Her brother!!! All she could think about at that moment was her brother and that monster cock of his. How it would feel having something that huge pounding into her, stretching out the walls of her box. Her hand went back over her clit, the other now grabbing at the head board of her bed. It was swirling the firm but soft pleasure point with furor at that point and Erica was letting out short little squeals aware that she might be heard if she let looses and she didn't want him to know she was there. She covers her mouth as she came, letting wave after wave of sensation tingle all over her body. Beads of sweat trickle from her brow and she comes down from the high, her hand never even leaving her loins as she drifts to sleep.
Morning came around, and Eric had jumped out of bed, threw on some sweats and went on customary 2 mile jog. The coach had always been a stickler for conditioning, he believed it was the most important part of training for football. Since his body was now "conditioned" to that of a machine of sorts, he could manage the distance in 20 minutes or less. Afterwards he came on back home and headed up to the bathroom, stripping down to get into the shower. He steps into the lukewarm water, letting the jets cleanse away his workout, not just from this morning, but the previous night as well. Suddenly he hears a knock on the door.
"Eric! You in the shower? I really have to pee!!!" screams Erica from the other side. It was safe enough, not like they didn't share this very bathroom before...
"Come on in, the door's not locked!" he replies over the stream of water cascading down his body. As she entered, he could see her through the frosted glass of the shower door, a blurry silhouette of a young woman who unlike him had sported a fit form for years and years. Erica was naturally curvy, full hips and a perfectly round ass, natural DD cup breasts, thick, creamy thighs and legs that went on forever. She had kind of favored natural beauties like Jelena Jensen or moreso Aria Giovanni, who's pictorial he was admiring the night previous, a night like any other night except that it felt a little different to him now that he thought about it.
"You know Erica, I gotta tell you...last night, I kinda felt like I was being watched for some reason...in bed...you know? Ever get that feeling?"
"You're just being paranoid, little brother..." she answered. Did she just call him "little"? Oh he was certainly not anymore, not in any sense of the word, but his notion made her dreadfully nervous. Did he know she saw him jerk his monster of a penis off last night?
"Where were you last night anyway? Thought you said you were gonna chill in the house?"
