Mark was anxiously waiting for the work day to end. Pacing back and forth behind his desk, with 15 minutes to go. He had made sure that everything he needed to have done was done long before the end of the day. Not only was it Friday but today was his 25th birthday. Normally he didn’t care about them anymore now that he was and adult they didn’t mean as much. However this year his wife, who was 4 months pregnant had promised him sex for his birthday. They hadn’t had sex since shortly after she found out she was pregnant. She just wasn’t turned on after she found out. She didn’t know why, and god knows Mark tried to turn her on, it just didn’t do anything for her. He understood but it didn’t stop him from craving her touch, hell at this point any woman’s touch.
He continued to pace, his thick cock growing hard in his pants as he thought of his wife’s petite body, firm ass and slight baby bump drove him absolutely crazy. He knew she would want to wait until after dinner and cake but he didn’t think he’d be in the door more than 2 minutes before he had his cock out and would be trying to get her naked. Down to 10 minutes to go. He was going crazy when his phone vibrated on his desk. He looked down and saw it was from Anne, his wife. His face lit up, hoping it was a teasing text or even better a risque photo like she used to send him. His excitement quickly turned to disappointment as he read the text. “Hi babe, so change of plans for tonight”, his semi-stiff cock softened as he continued to read, “Stacy is coming to spend the weekend to celebrate your birthdays, her trip got delayed, so we’ll be going out to dinner and she’ll be here through Sunday”. He wanted to scream but had to stay composed as he was still in the office. Stacy was was one sister-in-law he could stand, and they shared a birthday which meant they tended to see her on his birthday. But not this year, this year was supposed to best him and his wife as Stacy was supposed to be going to NYC for her 18th birthday. But apparently the trip got postponed a week so she was coming to spend the weekend with them. And he knew exactly what this meant for him. NO SEX! His wife, who before she was pregnant was normally ready to go when ever he wanted, had one hard fast rule. No sex when family was spending the night and no sex when they visited family.
He flopped down in his office chair and typed his reply “That sucks her trip got delayed, but great we’ll be able to see her and take her out for her 18th.” He might have been horny as hell, but he wasn’t going to let his disappointment show. He KNEW how emotional the pregnancy had made Anne, and also Stacy was the one good in-law so at least he knew he could make her 18th special and try to make up for her trip getting delayed. He send another text “I’ll call Bobby and see if he still has a table we can get”. Bobby was the owner of the best restaurant in town, now that his father had retired and one of Mark’s best friends so he was confident he could get them in to make the night special for Stacy. “Great, let me know” came a quick reply from Anne.
Mark dialed Bobby and let him know about Stacy coming for her birthday and it was last minute and asked to get squeezed in on the reservations. Bobby worked his magic, he always did for Mark, and got them a 7:30 reservation. Mark texted Anne again “Bobby is the best, as always, we’re in at 7:30. I’m leaving the office now”.
Mark gathered his things and headed out. As soon as the stepped out of the office the heat and mugginess hit him in the face. He was hoping it was going to have gotten better after it rained earlier in the day. Just another thing to make his night worse. He got to his car in the parking garage and cranked up some music, as well as the AC and started to head home. His mind still racing with the thoughts of sex and how bad he wanted, no needed it. Thankfully traffic was not too heavy tonight and he made good time home.
He walked in the door and both women, his sister in law was now a woman today after all were sitting at the table chatting. He did his best to keep a smile on his face as he walked in to greet them. Once he saw them, it was easy to keep it there. They were both already dressed for the night. They both stood to greet him. Anne was wearing a modest black dress that with her baby-bump, still showed off her curves and bump very well. And it was hugging his favorite feature of his, her tight, firm ass. However as beautiful as his wife looked, Stacy looked simply stunning. He couldn’t help but stare. She was wearing a very tight, form fitting red dress dress. He honestly couldn’t decide if he wanted to say something as the older brother-in-law or just enjoy the view of her now 18 year old body. He opted for the later. After all the dress looked painted on, formed around her 34B breasts perfectly, and amazingly, made her ass look even better. Both sisters had amazing asses after all, but he had never seen Stacy’s looking like this. He wasn’t sure if it was because she was finally 18 or because of the dress but he couldn’t help but stare and his cock throbbed all over again. He shifted uncomfortably, not wanting either of the women to see.
Anne gave him a hug and a modest kiss hello. Followed by Stacy hugging him extra tight and exclaiming “thank you so much for taking me out tonight. I was so bummed after my trip got delayed”. Her body being so close to his, made his throbbing cock become fully hard. He hadn’t had a woman hold him that close since before his wife was pregnant. He was torn between not wanting his arousal to how and enjoying the feeling of being that close. He also let the thought of fact that a tight, close hug being the most contact he has had, bother him slightly. He finally broke the hug and said he was going to walk the dog quick and then they’d leave for dinner.
They left for dinner, ate, and had a good night but the thought of no sex, yet again dragged on Mark’s mind. He did everything he could to not let it show. He didn’t want to ruin Stacy’s 18th birthday more than it already had been and didn’t want his emotional wife to catch on to his disappointment. After dinner and dessert, they paid the bill, left a generous tip and headed home. Anne was barely in the door and announced she was going to head to bed as she was exhausted. Mark stayed up for a short while to talk with Stacy but headed to bed shortly after as he was still horny as hell and didn’t trust himself to stay up with Stacy any longer as she was still in her little red dress and he didn’t know if he could control himself any longer. The last thing he did before heading to bed was worn Stacy that the window AC unit in the guest bedroom was on the fritz and showed her where the fans were in case it went out.
——————————————————————————-
Stacy went to the guest room and changed into her short pajama shorts and a tank top. She debated sleeping naked in case the AC went out but didn’t want to put clothes on if she needed to get up and get the fans. She was hoping her sister and brother-in-law would stay up with her for a while but understood them being tired. She was just bored and not usually in bed this early. She was also bummed about her NYC trip. She was planning on losing her virginity on the trip. She didn’t like most of the guys in the small town she lived in and even coming to the city where her sister lived she didn’t want to do anything there because even though the city was bigger than her town, her sister and brother-in-law seemed to know everyone and she was afraid of news of her having a one night stand to lose her virginity would get back to them. So she reluctantly climbed into bed and decided to sleep rather than dwelling on not being able to have sex this weekend. She’d just have to wait until her trip the following weekend.
She wasn’t asleep very long before the AC went out and not long after that she woke up dripping sweat as it was still super muggy outside. She stumbled half asleep to get the fans but they didn’t help at all. She tossed and turned in bed for a while before deciding she couldn’t take any more and decided she needed to go ask to sleep in the bed with her sister. She knocked on the door quietly and heard Mark’s groggy voice “yeah?”.
She opened the door slowly and explained what was going on and asked to sleep in their room. Mark, still being half asleep begrudgingly agreed. He already lost a lot of space in bed to his pregnant wife and her pregnancy pillow that kept her from sleeping on her stomach. And of course Anne was still passed out so Mark slid as close to the edge of the bed as he could and let Stacy slide in between them. He soon passed back out as he was only half awake anyways.
It took Stacy a little while to get comfortable between Mark and her sister. She finally got comfortable and fell asleep. It was almost midnight before she fell asleep. Due to lack of space it wasn’t long before she was curled up against Mark, her ass pressed against his crotch. They both slept curled up next to each other all night. It was shortly after 6:00am when Anne woke up and was slightly confused when she was her sister in her bed but figured the AC must have gone out in the spare bedroom again and slid out of bed to allow her sister and husband to continue to sleep. She walked towards the master bathroom quietly and as she did noticed that they were spooned against each other. She didn’t think anything of it as they were both sleeping, not realizing that the Mark’s cock was fully erect and pressing against her 18 year old sister’s ass. She slipped into the master bathroom, peed and slipped back out to head downstairs.
It was another hour before Stacy woke up, feeling her brother-in-law’s stiff cock against her ass. This just returned all the thoughts of sex and losing her virginity to the front of her mind. She considered sliding down his pajama shorts in order to see and possibly play with his stiff, thick cock. But her decency made her think twice about it. However she needed to do something. So she headed into the master bathroom and started the shower. She stripped naked and stood in front of the mirror admiring her naked, petite body as the water heated up. She cupped her small, perky breasts and let out a heavy sigh as she pinched her nipples.
Once the water was hot, she stepped into the shower and grabbed the shower head right away. She quickly, and easily positioned it into place, having done this more times than she cared to count at home. She turned the water onto pulse and easily found her clit with the spray of water. Her eyes instantly rolled into the back of her head. She l et out a low, heavy moan as pleasure raced through her head. She swirled the water expertly around her clit and her breathing quickened. She closed her eyes and imagined what it would be like to have a big, hard cock sliding in her and she played with her clit. It wasn’t long before she was imagining Mark’s stiff cock fucking her. She slid her hand down her firm stomach and quickly slide 2 fingers into her wet, eager pussy. She moaned loudly, almost too loudly. She even let “Mark” slip from her lips as she curved her fingers up to slide across her G spot. She was fucking her pussy hard and still swirling the water on her clit when her orgasm came out of no where and washed over her body. Her legs shook hard and she had to bit her bottom lip to keep from screaming. She was still picturing Mark’s thick, veiny cock sliding in her, in place of her fingers.
Her orgasm subsided and she slid her fingers out of her tight, virgin pussy. She moved her hand to her mouth and licked her cum off of her fingers. She returned the shower head to holder and began to wet her hair.
———————————————————————————————
Mark woke, groggy yet he knew right away that he was hard as a rock and the bed was empty. He didn’t even remember Stacy coming into the bedroom the night before. He heard the shower running and figured Anne and gotten into the shower. He got up and headed towards the master bathroom. Taking off his pajama pants and shirt as he went. He thought maybe Anne would allow sex even with her sister in the house since she was sleeping and the shower would muffle the sounds. He didn’t say anything as he entered the master bathroom. He slowly stroked his hard cock as he walked to the shower and slid back the shower curtain. He was shocked when it was his barely 18 year old sister-in-law in the shower. He almost screamed but realized his wife would hear. He quietly began to apologize. “I’m so sorry, I figured you were Anne, I figured you would have showered in the main bathroom”.
Stacy was just started to wet her hair, he was confused as to how he didn’t hear her come through there bedroom to get to the bathroom. Not realizing she had been in the shower long enough to masturbate and cum already. Stacy quickly looked down as his big cock that he was still stroking and explained shyly “No it is okay, um I was actually just thinking about you and that admittedly bigger than I thought it was cock”.
“Excuse me?” he said quietly.
She didn’t reply verbally. She simply reached out and put her small hand around his thick cock and gently pulled him towards her, forcing him to step into the shower. He was about to ask her what she was doing when she passionately kissed him. He wanted to push her away, but it had been too long since he was touched past a basic kiss and hug. So he kissed her in return and just let it happen. He wrapped his arms around her and quickly slid his hands down to her firm ass, squeezing it hard. She broke their kiss and slowly kissed up his neck and nibbled on his ear before whispering in his ear “take my virginity”.
The words had barely left her lips when she turned around and bent over. She reached behind herself and spread open her ass, showing off her puckered asshole and spreading her glistening pussy. Mark didn’t even think twice about it. He lined up his throbbing cock with her virgin pussy and gently pushed the tip of his cock forward. She let out a loud gasp as the head of his cock slide into her. Her tight pussy tried to resist his advancing cock, but he pushed forward. Slowly sliding in and out of her tight pussy. Finally reaching fully penetration. Once he was fully inside her, he held his cock there for a moment, while he reached in front of her and pinched both her hard nipples.
He left one hand on her breast and took the other and grabbed a hand full of her wet hair and pulled her head back hard as he began to fuck her. His pelvis pressing hard into her petite, firm ass, splashing water into the air with each thrust. Stacy slide her hand down and quickly found her clit and rubbed it as he pushed hard into her pussy, thrusting each inch of his thick cock into her. She wanted to scream in pleasure so bad, but knowing she couldn’t she instead sucked on two of her fingers as she began to orgasm for the second time this morning. Her pussy clenched and pulsed around his cock as she came hard, pressing her hips back into him as he pushed hard into her her. He pinched her nipple hard as she reached the height of climax. Her pussy squeezing hard his cock made him groan low.
Her orgasm subsided but he was still fucking her hard and fast. The force of his balls slapping against her ass, making a distinct sound. She pushed hard and fast into her tight pussy. Feeling as if it got tighter with each thrust. He groaned loudly and roughly said “Your tight pussy is going to make me cum”.
Stacy had a moment of clarity has he said that, realizing he wasn’t wearing a condom and she wasn’t on birth control, she pulled off of his cock and got in front of him on her knees. He wanted to cum inside her but knew he was too close to try to get her bent over again. He quickly stroked his cock and began shooting large, hot streams of cum all over her face.
As this was happened, Anne opened the bedroom door to wake them for breakfast, and realized both were not in bed, and heard the shower running. She quickly goes to bathroom and quietly opens the door, and walks to the shower, she yanks back the shower curtain, just as a third, large, thick load of cum splashes across her sister’s face. She simply smiles, and exclaims “honestly, I figured you two would have fucked last night after I went to bed. I’m surprised it took you to this morning.”
As the last stream of cum splashes across Stacy’s face, they both just look at Anne in shock, trying to figure out why she isn’t pissed. Anne just smiles “I know how horny I was at 18, and honey, I know you have been horny constantly since I’m not in the mood. And after I promised sex for your birthday earlier this week, I arranged for her trip to delayed so you could have it with her, knowing I wouldn’t be near wanting it. I figured the rest would take care of itself and my promise of sex would be kept”.
She laughed “well I’m starting breakfast, finish your shower and be downstairs soon to eat”. With that Anne walked out of the bathroom and left them to clean up.
