A party changes everything

© 2025 by incognito

After a twelve hour retail shift, with an hour commute either side, the last thing Rob wanted was to have to socialize, but he knew as he pulled up at home that the party was already in full swing, taking a few deep breaths he gripped his chin with his hand and sighed to himself in the cars rear view mirror,

“Let’s just get this over with”

Rob was in his early twenties, in his own opinion he was average in most regards, his girlfriend was, in that same honest opinion, well out of his league, she was hosting the party, though it was family so Rob was hoping for something that wouldn’t leave him throwing up into the small hours like a trip to several nightclubs. As he opened the door he was greeted by several cheers and loud music – he mentally booked himself some time to be emptying his stomach contents later, for now his girlfriend, Kate was handing him a drink and giving him a kiss. All in all not a bad thing to come home to he mused as he slid his arm around her waist.

Kate was outgoing and beautiful, the quintessential leggy blonde, tonight she was wearing a little black dress that showed off her figure perfectly, as Kate moved aside, Rob caught sight of Kate’s soon to be sister-in-law, Sarah, Sarah was a few inches shorter than Kate, and her shade of blonde came from a bottle, but she was just as pretty, she wore a white top and a mini skirt, whenever she got too close to the fridge her lack of a bra became obvious, a few of the guys at the party were trying to get her to drink a lot, but having been drunk on nights out with the both Kate and Sarah, Rob knew she could outdrink guys twice her size. Still tonight there was a look in her eyes that unsettled him. Trying not to think about it he gave Kate another kiss and finished his drink, making pleasantries to the few people he knew as he made his way to the bedroom.

As he walked into the room he was greeted by Spike, the German shepherd was very happy to see him, and spent a long time running in circles before laying down at Robs feet until Rob made enough of a fuss of him.

Rejoining the party, Rob went to the drinks cabinet and began making himself a drink. He felt a hand softly land on his shoulder, and turning around, he practically caught Sarah as she fell into him most of his drink went flying, he supported her as she took her time standing up, she never broke eyecontact as she ran her hand slowly up his chest from just above his groin. The party had started a couple of hours before he arrived, he made a mental calculation of how she could be drunk so quickly – having been out drinking with her before his experience was telling him that unless she’d been drinking pints of vodka, she was still nowhere near this intoxicated. Around them the party went on, the person who’d knocked Sarah apologised and moved on, Rob couldn’t help feeling that there was something he wasn’t quite aware of. Making up his mind he finished what was left of his freshly made drink and tried to find Kate.

Kate was outside on the decking area enjoying a quiet few minutes before returning to the party when Rob emerged, he looked flustered and a bit concerned as he sat next to her,

“Excellent party, as always” He began with a smile, then he fidgeted awkwardly, “What’s up with Sarah tonight?”

Kate drew a deep breath and held his hand, “You know her boyfriend, Matt? He broke up with her a few days ago” Rob nodded but didn’t say anything so she continued, “So, I suggested she come here” Kate paused a bit her lip, “and I thought you’d be a gentleman and take care of her for the evening?”

Rob felt his heart stop for a moment, “Wh… why me? We’ve got friends who are single…”

Kate now looked him in the eyes, “You’re a great guy, kind and considerate. She just needs someone to be nice to her, show her that she can have fun and not have to do something she doesn’t want to”

Rob rubbed his forehead, “and if she tries it on? I mean I love your dedication to the cause, but she’s wasted already”

Kate smiled and kissed him, “That’s why it has to be you – I know you wont take advantage of her”

Rob held her for a few more seconds then more noise indicated that others from the party were making their way outside. Kate began making conversation as Rob headed back inside,

“There you are” Sarah’s voice called out as he came back through the patio doors, she handed Rob a new drink, “To replace the one you dropped when I fell for you” she said with a sly smile and a wink. Rob laughed as he drank it, nearly spilling it again, Sarah cheered as if she’d scored a point in a game.

Rob was talking to Sarah for most of the night, she was getting more drinks for them, thanks to Kate he knew to avoid the topic of Matt. Before they knew it most of the guests had left, Kate came over and sat on Robs lap, leaning back to kiss his neck she announced that she needed to go to bed, Rob went to stand up but was surprised when Kate tapped him on the nose, “Yew can’t leave a lady all by hershelf” She slurred as she gestured from Sarah to the empty room.

Rob grinned and nodded, then stood up, “I’ll be right back, just got to get her to bed” Sarah made a face and let out an ‘awww’ sound before going to make another couple of drinks.

Upstairs Rob helped Kate to the bedroom, Spike immediately left the room as the door was opened, “I’ll try not to take thasht peshonally” Kate laughed as she watched the dog make for the stairs, Rob helped her undress, the sight of her naked body took his breath away, he slid his hands over her toned stomach and around her perfect D-cup breasts as he kissed the back of her neck, Kate spasmed slightly as he nibbled her earlobe in just the right way, she could feel her nipples become erect as his hands waved over them, he moved to put his hand between her legs, they opened slightly her body reacting automatically he could feel the heat eminating from her as he was almost in position to bring his finger up her shaved pussy and use her natural lubrication across her clit, she turned to put her body against his, she moved his hand onto her shoulder instead, “I love yew” she mumbled into his chest as she pulled herself close to him, “But tonight yew have a job to do” she followed up with another drunken tap on his nose followed by a second tap on his bulging groin, “probably best to hide that tho” she said with a giggle as she slid into the bed, “Don’t want her gettin that…” Rob was about to say something to reassure her, then Kate continued “…Not yet” before immediately falling asleep.

Not sure of what to make of Kates words he adjusted himself so that it wouldn’t be obvious that he was walking into the room with a raging boner after his encounter with Kate, then Rob made his way downstairs, the house seemed very quiet and empty after the party, Sarah was sitting on the sofa waiting for him, another drink ready she patted the seat next to her, Spike was laying on his bed in the corner of the room, licking himself, “Shall we?”

The two drank some more and talked for a few minutes before Spike came over to them, she sat in front of Sarah and sniffed her leg, she jumped from the cold wet nose and the lick. Rob went to move him but she gave a sly smile and stood up, Spike backed up unsure what to expect as she bent over at the waist to give Rob a look down her top at her breasts, completely unencumbered by a bra, she reached under her short skirt and pulled down her thong, “This is probably what he’s after”

Rob could barely breathe, as Sarah stood up and offered her underwear to Spike, who took it with him back to his bed. Rob was still trying to make some sense of the situation as Sarah straddled herself across his lap, she leaned into whisper into his ear,

“Your last drink had a little something in to help get you in the mood” she leant back and started to pull her top up over her head, Rob finally managed to get his body to respond, he reached out to stop her.

“I’m not sure you put it in the right drink”

Sarah blushed as she slowly ground her pussy against the bulge in Robs trousers, she threw her top to the other side of the room, her body really was similar to Kates, she fondled her breasts as the nipples became erect “It was in both” she stood as she removed her tiny skirt, unbuttoning his jeans she had started pulling them off when she gave a soft moan.

Spike had come to investigate the discarded top, but the smell of Sarah’s thong couldn’t compete to the source, Sarah wasn’t prepared for the sensation as the dog found her clit, her juices encouraging him onward in his searching. She was torn between moving him away and trying to let him have easier access, as she paused the dog saw its opportunity and redoubled it efforts making the decision to stop him even more difficult, writhing in pleasure she suddenly remembered she wasn’t alone, she looked up from Robs lap expecting some form of disgust, judgement, or shock but found he was clearly enjoying the impromptu performance, she forced her arms to move and pulled Robs trousers off, his boxers coming with them until finally his cock sprang free, Sarah knew that Kate and Rob had both been virgins when they got together, so Kate didn’t have a frame of reference for what she was seeing, Sarah however could see that at around eleven inches Rob wasn’t just long, he was huge. She arched her back as a wave of pleasure overcame her, Rob put his hand to the side of her face and she guided his rock hard cock into her mouth. As she began to suck she could feel more waves of pleasure hitting her from the dogs attentions, her legs opened wider and she bobed her head up and down, muffled moans escaping alongside desperate breaths as she took more and more into her mouth and throat.

Spike, however, had other ideas, so focused on sucking the magnificent cock in her mouth she barely noticed that the licking from behind had stopped, not that Robs’ grip on the back of her head would’ve allowed her to turn around to find anything out. Then she felt the dogs weight on her back, the booze and drugs she’d put into her own body wouldn’t let her try and escape as she felt the front legs grasp her waist, the scratching from the claws sending her on yet more waves of pleasure, a small part of her brain told her that something was about to happen, she opened her eyes to see Rob in ecstacy, then there was a hot wet probing at the enterence to her pussy. As Spike found his mark he hammered it home, her whole body vibrating with his thrusts, she pushed back into him as he pushed forward, she felt him get bigger every second, then as she felt him pounding against her cervix something else was growing, the base of his doggy cock was now too big to come out, she was stuck there, knotted to him. The sight of such a successful mating proved too much for Rob, he unloaded his cum straight down Sarah’s waiting throat, this, along with the feeling of the knot rubbing against her g-spot sent her into multiple orgasms, every pulse of Robs cock, and every twitch of Spike sent her higher and higher, then as she thought she could take no more she felt Spike begin to cum, if Rob had been a large load, Spike was something else entirely. Her pussy was plugged by the knot, she could feel it filling her up, his doggy seed desperately trying to get his bitch pregnant.

As Robs cock slid out of Sarah’s mouth, she moaned with pleasure, looking up she could see that Rob had a hold of Spikes’ collar and was keeping him still, she mumbled “Thank you” between orgasms.

Laying with her head in Robs lap, barely able to keep her eyes open Sarah didn’t know if she’d ever be free from Spikes knotted cock, it felt like it should be getting smaller, eventually, about half an hour the knot slipped out, followed by a wave of dog cum, Spike immediately started licking around her pussy for a few minutes, though by now her body had nothing else to give, she felt herself being carried and she put her arms around Robs neck, bringing her to the second bedrooms ensuite he placed her onto a large towel over a small chair she could see a river of dog cum spreading out from between her legs, still on a high after the unending waves or orgasmic pleasure she didn’t expect Rob to stick around, so when he began to run her a bath she was mildly and pleasantly surprised, he carried her over to it and gently placed her inside, running his hands over her body and gently cleaning her scratched sides with a soft sponge, she rested her head against him as she spread her pussy lips open and began to try to wash herself, “next time: remind me to put socks in him” she muttered as she kissed him.

The next morning Rob and Kate were having breakfast as Sarah walked in, she was still moving with difficulty after the energetic display she had put on the night before. Rob passed Sarah some toast as Kate began to speak, “Hey, great party right? why don’t we put the TV on?” She asked, then as they sat on the sofa together with Kate in-between Rob and Sarah, Kate spread out her arms around Rob and Sarah’s shoulder hugging them close, the TV came on and was showing a woman on all fours sucking a guy off as a dog mounted her, Kate and Sarah could only giggle at Robs confusion, Kate spoke first “Sorry to have drugged you last night” Kate played with his hair, Rob still couldn’t find words, watching Sarah on screen writhe with pleasure, Sarah on the sofa spoke up “I’ve had a lot of bad relationships, when Kate suggested joining you two, I wanted to be sure…” Rob nodded slowly, Kate spoke again as on screen Rob was ejecting his load almost directly into Sarah’s stomach “Think of it as our way of asking you to be something special to both of us”

Rob nodded and Kate straddled him as Sarah had last night, “Yay!” She giggled gleefully, she looked at Sarah and gave a sly smile, she called out in a sing song voice”Sp-ike…”

Sarah was putting socks on the dog as Kate was taking her clothes off and gaining access to Robs cock – Life, Rob mused, was about to get a lot more interesting.
