Steve watched as the large cock disappeared into her mouth. Her lips wrapped themselves around its girth, gliding up and down its length, her head bobbing merrily as Gavin looked down at her.
As he watched, Steve freed his cock from his shorts and wrapped his hand around it, wishing it was his cock that the mouth was wrapped around and loving. He stroked his cock as it filled out to hits full size, swelling as his fist pumped up and down the shaft in time with the mouth on Gavin's erection. He wished that he could be inside the room, rather than out here, peering in through the window. But there was no way that he could do that. He took some comfort in the fact that if he couldn't have Julie, at least his cock was bigger than Gavin's.
He eyed the girl up and down as she continued her oral performance inside the bedroom. She was slim, athletically so, with blonde hair cascading about her face, occasionally obscuring his view, but being pulled out of the way regularly enough to keep him interested. He watched her mouth for a while, the lips full and gorgeous as they parted to allow the long, almost serpentine tongue swirl about the head of the cock. They were a lovely pair of red lips, the colour setting off beautifully against the bronzed skin of the girl's face, which was smooth and almost elfin in its beauty, the cheek bones high, her eyes almost catlike in shape, a scintillating green in colour.
His eyes travelled down over her shoulders to where he could see her lovely breasts falling beneath her chest as she knelt over her boyfriend who was laid back on the bed to enjoy his girlfriend's performance. The nipples were tight and erect, obvious even from his vantage point outside. Her waist was narrow and her hips spread just enough to show off some womanly virtue, but not so much that you would ever consider her 'Rubenesque'. Her butt was tight and her legs long and slim from all the running that she did.
Steve pulled again and again on his cock as the girl continued to suck on her boyfriend. She held her head still and took the cock in her hand, pumping it and Steve watched intently. He could tell from here that Gavin was cumming and that the girl was swallowing it all! It was too much for Steve and he allowed himself the release he'd been seeking, his own cock exploding and blasting sperm all over the wall below the window.
As Julie clambered up alongside her boyfriend on the bed, Steve wished that his cock, like Gavin's had been able to spray its seed down her throat. But it wouldn't be right to do that to your sister, so Steve just watched. He stayed awhile to see if his younger sister was about to take things further, but she and Gavin just lay there and Steve decided that he should get inside before their parents came home again. He went back inside to the TV, to await the two young love birds time to come back out.
Their parents had gone out and left the three of them at home, expecting that they would all sit down and watch a movie, but Gavin and Julie had quickly made their way off to her bedroom, asking Steve to cover for them. He was jealous that he had to sit here and cover for his sister whilst she went off and kissed her boyfriend in her room. As he sat watching the movie, waiting, he had gotten curious as to what his sister was actually doing and had gone out into the yard just on the off chance that he could see something.
He was amazed when he realised that they had the light on and hadn't pulled the curtains closed ... he could see them as clear as he could wish for and had then stood mesmerised as Gavin had pulled Julie's top off over her head to reveal her bra clad breasts.
Steve had watched his sister's breasts with interest for a couple of year's now as they started as just budding little things on her chest and gradually filled out to the C cup size that they were today (he knew her cup size, because he'd kept an eye on the changes to her underwear as it hung upon the line over the same year's he watched her sweaters fill out).
Gavin had started to suck on her breasts and Steve found himself with conflicting emotions ... lust as he saw her nipples pulled and stretched and worked over ... arousal as his cock reacted to the scene before him and shock that he was getting so turned on watching his own sister! Shock that was surpassed when Julie had pushed her boyfriend back on the bed and pulled his pants down and started to suck on his penis! Steve hadn't managed to get that far with his girlfriend and his little sister was already doing it to her boyfriend!
Just thinking back over it had given Steve another erection and typically, Gavin and Julie chose that moment to join him back on the couch. As they sat down, Steve asked if they wanted a drink, getting up to get one for himself, with some small hope of hiding his erection until it subsided.
As Steve stood up to go get the drinks he'd offered, his crotch passed at eye level before Julie, who nearly gasped out loud at what she noticed. She quickly looked at Gavin to see if he had seen it too, but he was too busy trying to see the movie. She'd never really looked at her brother's crotch ... he was her brother after all, but just then when he'd walked in front of her, it was hard not to notice the enormous bulge in his pants.
With the taste of her boyfriend's cum still in her mouth and her insides churning from the release that she hadn't managed to achieve for herself, she became acutely aware of the slimy state of her panties, wet first from giving her boyfriend head and now even more so because she had just seen a hint of the size of her brother's cock.
She couldn't believe that she was being turned on thinking about her brothers' dick and tried to concentrate on the movie instead. Steve returned after a bit with the drinks and sat down next to her on the couch as Julie was in the middle with Gavin at the other end. Julie's eyes were drawn to his pants as he walked in front of her again and although his erection had subsided somewhat, she could still make out a large enough bulge to get her excited again as he sat down.
Just before the movie ended, their parents arrived home and all thoughts of her brother's dick were pushed from her mind, but later that night, Julie lay in her bed, naked, her legs spread and her fingers working feverishly on her clitoris in an effort to release the tension that she had managed to build. As she stroked herself, she remembered the gush of Gavin's cum into her mouth, the feel of the smooth skin of his cock in her mouth ... but superimposed and interspersed on all the images was a vision of the bulge in her brother's pants.
As she came, her juices oozing down her bum crack from her pussy, Julie lay wondering how on earth she had just managed to cum whilst thinking about her brother's dick.
