My girlfriend (Molly) and I, both 26, hosted our first sex party last weekend. I've been attending swinger's events for a few years now, and I got Molly into it when we started dating about 6 months ago. We've been to a few parties since, then Molly suggested we should organise one. She said one of her closest friends, Olivia always mentions how she'd like to go to one whenever Molly is talking about what we get up to, and Olivia would come if we had a party. I like Olivia, she's really pretty, but I didn't think she's a good fit for a party like this, she's always very quiet and awkward. I imagined her just standing in the corner not talking to anyone or following Molly around like a shadow.

I agreed that we should organise a party, but would rather we kept it small. We talked about who to invite, and the first thing out of Molly's mouth was "Well we need to invite Scott". I met Scott years ago at a party and we've became good friends since. Scott is always very popular at these parties, he's very outgoing and incredibly well hung. I'm just about 8" long, and Scott's probably got another couple of inches on me. Scott hosted us at a party a few months ago, and it was fun to see Scott fuck Molly, up until then, I had been the biggest guy Molly had been with. It was a. no-brainer that Scott was coming, plus Olivia, a couple we've played with a couple of times before and a new couple that we'd met on an app and were excited to meet completed the guest list.

We were all set for the party, then last week Molly comes home from the gym and tells me that she was talking about our party with her personal trainer, Sophie, and Sophie said "So, where's my invite?". She couldn't tell if she was serious or not, but apparently Molly was telling her about her time with Scott after our last party, and it seems Sophie was pretty interested in meeting him. I wasn't familiar with Sophie, so I didn't know whether she'd be a good addition or not. Anyway, Friday afternoon comes along and Molly gets a text from Sophie asking our address, so it seems like she's coming.

When everyone arrived, Sophie was definitely made quite the first impression, she was very sexy, nice toned body, obviously as she's a PT, wearing a sexy red lingerie set with a bra that was too small for her C or D cup tits and a little g-string that was no match for her cheeks. Everyone else looked great too, although Olivia predictably was dressed more for a regular party than a sex party.

I couldn't quite enjoy the party as much as I normally do as I was trying to make sure everyone was enjoying. Scott was playing with one of the other couples, I could tell Sophie wanted to join in, but wasn't too sure how as it was her first party. I took her into the bedroom that the others were playing in and gave her a kiss and started to grab her arse. She started rubbing my cock over my underwear before taking in out and dropping to her knees. Molly came in to help her out and they both went down on me. I loved listening to Sophie choking as she tried to deepthroat me. Scott had finished playing with the other couple and came and stood next to me. Molly made a move over to start going down on him. Instead, he grabbed her and flung her down on the bed, grabbed a condom and started pounding her. Sophie and I stopped to watch the two of them, I kept rubbing Sophie's pussy and I could feel her getting wetter and wetter as we watched Molly's big E cups bouncing around, her moans getting louder and her face and chest turning red as she's powerless to do anything about it. After about 10 minutes, Molly's legs start to shake and she cums.

Scott only has a few minute to rest before Sophie boldly proclaims "My turn!". I take Molly to recover in the living room, still a little wobbly on her feet and leave them to it. Olivia, still fully clothed, said to Molly "OMG that looked intense, I've never seen anything like that". I asked her if she was enjoying herself, she said yes, but I wasn't convinced. I asked if she wanted to join in, again she said yes. I asked her if she'd be comfortable getting down to her underwear like everyone else. She did. She had a figure of an in-shape girl who has never been to the gym. By this point, Sophie is getting more than she can handle in the main bedroom, and everyone else is in the second bedroom, so I guide Olivia to the sofa, remove her underwear and go down on her. She really loosens up after that, and starts to enjoy herself. She returns the favour and starts to blow me, mentioning that she's never been with a guy as big as me before, which is nice to hear after Scott getting all the attention.

Eventually, the second bedroom becomes free and I take Olivia in there, with Molly coming to watch. I had all night of sexual tension to unload, and Olivia was the perfect release. We gave Scott and Sophie a run for their money in terms of noise. After a few minutes, Olivia squirts. I keep going, then a little while later she squirts again. Then again. "I didn't know you were a squirter" I said. "I'm not" she replied. I loved that, gave me extra motivation do go even harder. Eventually I finish and blow a huge load. The three of us lay there and start talking, Olivia said she didn't know what happened with the squirting and that she "hadn't been fucked like that before". I said not to worry and it's actually a massive turn on. Round 2? I asked. Olivia laughed and said yeah, but I'm a little tender so be careful. Molly left to go join one of the other couples. I was a quite disappointed I didn't get the chance to fuck Sophie as she was a total 10/10 with a killer body, hopefully I'll get the chance eventually
