A no. 2 card

As John drew his card he was slightly apprensive about what it could entail, and when he read the card his nerves certainly didn't leave him. The card had a Emboldened gold 2 on the top with a subheading of Exhibitionism, it then explained that his task was to go outside into a wide open space and masterbate till climax, it then specifies that no outside influence can alter your task.
After enquiries from the others, John explains his task to the others and following the giggles and encouraging comments he begins to stand up and head outside. He decided to go sit down on the front garden and began to hesitantly unzip his jeans, as he pulled them down enough to pull out his hard cock he noticed Mrs Johnson over the road putting out her washing, she was about 40 and had a son and a younger daughter. She had dark hair and big tits and was quite curvy but was by no means fat, John would often see her jogging in the evenings. He'd always found her attractive but not particularly amazing; however now with his solid cock and her putting out her and her son and daughters underwear he began to find her increasingly arousing.
He began stroking and watching her as she bent over to pick up her basket showing her ass, as she strightened up she noticed him lying therewith his trousers undone. She walked over and seductively asked " you want a bit of help with that?" pointing at his cock.
"yer, please Mrs Johnson" he nervously confessed.
Then his older neighbour smiled and got onto her knees, she put out an outstretched hand before he heard rapid knocking on the window. As he turned he saw his sister Fiona holding up the card and then shaking her finger to remind him that he couldnt have any help with this.
He explained that they were playing the sex game to which she replied "oh, i love that game!" with some enthusiasm before saying "oh well, maybe you'll need some help with that task..." she immediately began groping at her sexy tits and squeezing at her hardening nipples. She then turned around in doggystyle showing him her ass as he kept pumping his shaft, continuing in this position she undid and wiggled out of the top waist half of her jeans showing off some black satin panties.
John was beginning to feel like he'd cum soon, as he groaned slightly Mrs Johnson realised this and rubbed her ass more through her panties.
"I'm gonna cum!" she then spanked her ass, and taking that as an invite, John raised onto his knee's and with a groan shot streams of his white cum all over her black panty covered ass.
"Oh yes John!" she yelled as his orgasm finished dribbling out the last of his cum right over her asshole. Looking at her cum covered panties she said "i think i'll have to change these, while i'm in my house could i fetch my two and then we could all join you?" nodding at the 3 gorgeous ladies in your lounge.
"Yes! Course you can! I mean, i'm sure it'll be fine" not trying to seem too eager. She smiled before taking off her panties, being careful not to lose your cum and saying "You can take these inside, maybe your sisters will like them" and with a wink she turned around and headed into her house to fetch her children.
When he went in, Fiona and Daisy were quick to grab the panties and lap at all his cum and with a white mouth and tongue daisy enquired "did she say she was coming to play with us?"
"Yep, and she's bringing her kids too"
"Cool! The more the merrier- plus, Luke and Jenny are hot!"

The doorbell went and your mother went to let the trio in. Luke came in first, he was tall and athletic and the girls looked excited to see him, then Mrs Johnson wearing tight black trousers and lastly was Jenny, she was gorgeous; she had almost black hair framing a really pretty face with a slim body, B, possibly C, cup tits and an amazingly tight ass.
"So, who's turn is it?" Mrs Johnson asked.
