It had been just over six months since nineteen-year-old Jenna's parents had divorced, and a little over two months since her mum Tina had brought her new boyfriend Dave home to meet Jenna. She'd told her that she hoped this would work out and hoped Jenna would accept Dave into the family. Jenna had been very close to her dad, but that had been thrown out of the window after finding out he'd been having an affair.
While trying to sleep that night she'd realised that the signs had been there. She covered her ears, trying to drown out the loud moans and groans from the neighbouring bedroom where her mum and Dave weren't being too subtle about having sex. Jenna thought back, it was a sound that had been infrequent when her dad was here, probably due to him saving himself for elsewhere instead. It was worse two nights later when her university friends were around to watch a film, and spent more time giggling while listening to the porn-like sounds coming from upstairs.
"What?" her mum asked when she came down to make drinks, "It's not like you lot are all virgins."
"I'm pretty sure the whole street could hear you!" Jenna exclaimed.
The others all giggled again while her mum pulled a face at her.
"You sound a little jealous darling," Tina laughed, "we'll try to be a little quieter later."
Jenna groaned knowing later meant sometime that night. Time to put on headphones and listen to music she thought to herself, that way I might just get some sleep. Once her friends had gone she laughed to herself. Dave seemed okay to be fair, they hadn't really spoken too much but he did always say hello and seemed pleasant, he was treating her mum well even though it was early days, so she'd give him the benefit of the doubt for now.
Things changed a few days later. Her mum upstairs changing, Dave used his newly cut key to let himself in and shouted hello to Jenna, smiling broadly. As Jenna turned to say hi back, she stopped and stared. A young version of Dave followed him in, although he was taller still. Dave was around six feet tall, which seemed tall enough as Jenna and her mum were only 5' 3". Younger Dave was around four or five inches taller than him, his head shaved or he would have looked even bigger.
"This is Dean, my son, he's just finished at University so will be moving in too, if that's okay with you?" Dave said, finishing the sentence and looking at Jenna's mum who'd come downstairs.
"Sure, not a problem, we can put a bed in the spare room next to Jenna," Tina announced.
Two days later Jenna was sitting eating breakfast when a blonde girl walked in and started making herself some toast. Jenna stared at her, asking what she was doing. She wore an open shirt far too big for her, presumably one of Deans, and just a pair of skimpy briefs underneath. Her firm large breasts pushed the material open showing her stomach.
"Dean told me to help myself to food while he, erm, regains his energy," she giggled, "You must be Jenny, right?"
"It's Jenna actually," she scolded, "are you his girlfriend then?" she asked.
"Well I was last night, and again this morning, and probably after he's drunk this coffee," she giggled again.
Jenna watched her take a tray and put the mugs and toast on it before slinking off towards the stairs. Her arse swayed as she moved, and Jenna looked on in dismay. She glanced at herself in a mirror. She wasn't too bad looking she thought, but nowhere near as pretty as the blonde girl had been. She looked a little further down, bemoaning her 30A cup chest, wishing she had tits like the blonde girl had.
Jenna sighed. It was a feeling she was all too familiar with. All of her friends were similar, not quite as perfect in the breast department as Dean's conquest had been, but all bustier than herself. She had gotten used to it, when they were out men always stared and pointed at her friends, but not usually at Jenna herself. She'd had boyfriends of course, but they never seemed to stick around after having had their way with her.
A couple of her friends were at her house later before they went to a local club. Tina and Dave had come back from work, changed, and gone out themselves. Dean came downstairs, grunted, and made himself a drink, much to the delight of Jenna's friends. He wandered off back upstairs and must surely have felt two staring sets of eyes burning in his back.
"Fucking hell Jenna he's hot," Diane told her.
"He's alright I suppose, but he's practically my step-brother," Jenna answered.
"I wouldn't care, I'd still let him have me if I were in your shoes," Jodie told her, laughing loudly.
They teased her further, more so once the drinks had flowed.
"I wonder how big his cock is, I wonder if it's in proportion to how tall he is?" Diane giggled.
She exaggerated holding her hands wide apart, Jodie laughing that If he was that big you wouldn't be able to walk afterwards. They fell about laughing again while Jenna joined in a little begrudgingly.
"Jenna, take a photo of his cock to show us," Jodie instructed.
"He's not going to let me do that, he barely speaks to me," Jenna gasped.
"Then you'll have to do so sneakily," Diane told her.
They went to get food before the girls went home, and when Jenna got home later Dean was sitting watching TV and merely grunted towards her when she said hello.
"Are mum and Dave in?" she asked.
"They'll be back late Jenny, they've asked not to put the door chain on if we've gone to bed," Dean answered.
"It's Jenna!" she retorted back.
