Mike couldn't get any satisfaction. During the skype session earlier in the evening, he had been surreptitiously whacking off under his Dad's desk. He'd nearly shot his load when Jenny was getting sprayed by Steve's cum, but the unexpected ending of the video link had left Mike with a raging erection and no stimulation. He would normally have pulled up a porno movie on his laptop, but the situation had become more complicated by the unexpected arrival of his sister Hannah and her boyfriend Tony in the office.
"Oh! Hey Mike," said Hannah, surprised to see him there. Mike noticed she quickly straighten the top of her dress, which had probably just had Tony's hands in it, pawing at her tits. Mike caught a quick glimpse of a black lacy bra beneath her short white dress. Hannah's long red hair and bright green eyes made always made for a stunning sight, but she looked especially hot tonight: The dress was tight around her small but perky tits, her legs looked even longer than normal as she stood casually in her stiletto heels. Mike's cock started to harden again under the desk just watching her: He had ignored or fought with his sister for years as they grew up, but at 19 she'd become a frequent focus of his late night fantasies, which mostly involved Hannah's eyes smiling at him as she slowly took every inch of his hard cock into her willing mouth.
"Er...we were just going to pick out a book from Dad's library," Hannah said.
"Yeah, sure," said Mike rolling his eyes. "There's hardly any brandy left, but there's still plenty of single malt whiskey."
Hannah giggled and smiled at Mike "That obvious huh?" She reached over to stroked his face gently. "You won't tell Dad will you?" She'd clearly had a few drinks already, and Tony was standing right behind her, trying (but failing) to touch up Hannah's ass without Mike seeing.
"Huh? Oh no, no, I won't say," Mike mumbled. His naked prick, under the desk was just a few inches from his sisters thigh, and the knowledge was making him even harder. He pretended to finish working on his laptop, and waited until Hannah and Tony started fixing themselves a drink from his Dad's "secret" bar in the bookcase. Quickly and quietly Mike tucked his dick back into his pants and zipped up his jeans, then he yawned and said goodnight as he left the room trying to keep the prominent bulge in his pants out of eyesight.
Hannah and Tony came upstairs soon after their nightcap. Within minutes Mike heard the rhythmic squeaking of the bed springs as things moved along in the next bedroom. Hannah was the classic cute and friendly girl-next-door: the sort who loved to babysit and help with charity events and got straight A's at school and college without every seeming to study. But since she'd found sex with her first long term (now ex-) boyfriend Jake, Mike had seen (or rather heard) a whole different side of her. He was well practiced at finding the best spot to listen in on his sister, and moving to the back of the closet where the wall was thin, could hear all the sounds as he was in bed with them.
"Hey, Hannah," Tony said. "You like my big fat cock in your tight cunt?" Not very subtle, but Hannah seemed to like this stuff.
"Ungg, yeah that cock is soooo hard... go faster now Baby...God I'm so wet! My clit gets so hard when your massive cock is in my pussy – do you feel my hard clit? ....I love it when you put your finger on my asshole – will you touch my ass while your thick cock fills my cunt with jizz, Baby?" Wow, thought Mike, she was on form tonight.
Mike was beating off in time with the rapid pumps that Tony was delivering to Hannah's pussy. Mike had been trying to work on some tantric stuff he'd read, about men who could have like five orgasms without ejaculating. He'd got quite good at it with his girlfriend Angela, but the sounds of Hannah squealing "I think I'm gonna cum.... I'm gonna cum on your hard cock Baby!" was almost too much for him.
All too soon though, Tony was grunting and moaning like he was spraying a load into her tight snatch. Hannah was crying out too, but it sounded more frustrated than blissful to Mike. When Tony finally finished, the room next door quickly got quiet. Mike started up his computer again and was going to finally get some relief watching that porn movie, when he heard Hannah's bedroom door click. He moved to the door, hoping to see his sister's naked body going to the bathroom, but instead nearly bumped into Tony who was slipping on his jacket while heading toward the stairs.
"Shit, you surprised me!" Tony said. "I've, er, got to get home before midnight. Umm, a big exam tomorrow."
"Right," Mike said. From what Mike had heard, Tony hardly ever attended any of the college classes, spending most of his time trying to juggle multiple girlfriends. The sleaze ball was probably going to see another one right now! "Yeah, it's a bummer about those Saturday morning tests."
"What? Oh... yeah," Tony continued lamely. "Well, Hannah's asleep, so say bye for me in the morning OK?" He crept down the stairs and, quietly opening and closing the door, was gone.
Though Mike knew it was wrong, he couldn't resist taking a look at his sister while she slept. The hall light was enough to see that she'd fallen asleep on her belly, with her body half covered by the sheets. He could see one perfect, tight globe of her ass, and those long, long legs, her red hair in disarray down her back.
Her steady breathing made Mike more confident. He stepped into the room, walked quietly over to the bed. He could see her black bra and a matching thong laying discarded on the floor next to her crumpled dress and heels. A sudden wet squelch beneath his foot made Mike realize he'd stepped on the condom Tony must have used. He cursed Tony under his breath – what kind of pig just throws a loaded rubber on his girlfriends carpet? – but after he'd had a chance to get over feeling grossed out, Mike realized two things: First that Tony must have shot about a half cup of semen into that thing and second, that Hannah's pussy would be nicely fucked but not full of jizz.
Mike leaned over his sister's sleeping body and looked down between her legs. Her cunt hairs were moist and tangled and a beautiful smell came from her – the scent of a recently fucked pussy. Mike moved closer still and put his head down over her butt so he could breath in the odor. He cautiously slid a finger gently along her ass cheeks and ran it between her thighs to caress her pussy hairs. With no reaction, he became more bold and slid two fingers over her puffed up pussy lips, feeling the warmth and moisture. Hannah stirred a little, and Mike froze. She settled back down again and Mike continued his slow careful caresses, moving a finger along the line of her slit, which easily opened up to receive one then two fingers. Hannah's pussy seemed to suck them in, and Mike just let it happen, sliding his fingers around in the welcoming wetness. He slid his fingers in and along her lips like he was in a dream, marveling at how hot she looked and how inviting her snatch was.
Suddenly. Hannah half awoke and sleepily said "Hmm, what're you doing, baby?"
Mike thought frantically. "Shh," he said in what he hoped was a fair match for Tony's voice "Shhh, shhh."
"Hmmm that feels nice," Hannah said, as she reached out a hand to Mike's naked leg. Mike froze again as Hannah's hand worked its way up his thigh and quickly found his stiffened cock. "Are you ready to go again?" She asked, surprised. "Quite the stud tonight! Wanna fuck my pussy again, Tony? It needs fucking... will you help me with your massive cock? Please mister?"
Hannah was insistently beating Mike's cock as she said this. Part of him wanted to go on forever, but he was worried that she'd roll over and see him. The hallway light had gone off automatically, and so the room was pretty dark, but he couldn't take the chance. At the same time he couldn't just stand and leave which would be really weird – who would do that when his hot girlfriend was begging to be screwed. But he couldn't fuck his sister...could he?
Hannah started to roll over. "Do you want me to suck on it?" she said.
