So, it's been several weeks since all of this shit began. I'd managed to keep it all from my girl, thankfully, but things were starting to escalate slightly. One night, out of the blue - when I was watching the TV with my girlfriend - I got a text message:
"Add me on Wickr, usr is xxx, delet dis txt"
My heart skipped a beat. Either Shannon was getting stupid, or more brazen. She usually only text when I was at work or if she knew Rachel was out. Surely Shannon was just as complicit as me in all of this now, right? Right!? I hastily deleted the text, hoping I'd committed the username to memory. The fuck is Wickr, I thought. Something like Kik, I supposed.
"Who was that?" My girlfriend asked me.
"Just the boys," I lied, "off out for some beers. I can't be bothered to go, though, I'm too tired."
Seemingly happy with that response, her attention turned back to the television.
To recap, for those who are just joining us, last time I recounted how Shannon left a change of clothes at my house and well, long story short, she caught me washing her panties after I'd used them to jerk myself off. Since then, she had extracted a total of Β£300 from me in blackmail money. She had given me an additional two pairs of panties since, in return for more money. My "relationship" with Shannon had started as good ol' fashioned blackmail, but she clearly was starting to have fun with the situation. She was fucking with me, pushing things and having fun. She was playing with her food like a cat bashing a mouse about.
Her and her boyfriend Nick were trying for a baby, and more often than not, the panties she was scalping me out of Β£100 a go for contained more than one person's fluids. I'm sure some guys are into that, but the stinger for me was that I couldn't yet even bring myself to jerk off in the panties she gave me. They were already covered in whatever quantity of her boyfriend's jizz that had trickled out of her when she had been wearing them.
The first pair I received that were already full of cum she had given to me in person right in my living room. At the time, I just laid them flat in front of me and added my own cum to the material, so worked up I was about my girlfriend's best friend handing me worn panties in my own house. It still gives me shivers now.
So basically, what had escalated from an innocent sniff to a quick wank had cost me dearly, and continued to do so. I was starting to feel that I was no longer getting anything out of this arrangement. Until of course, she started pushing things to the next level.
Anyway, later than night, I downloaded the Wickr app onto my phone and added Shannon's username. I sent her a basic message that said hello.
My phone buzzed.
"Took ur time replyin," was the only message that I received back.
"I've been busy," I responded, angry at her attitude.
Buzz buzz.
"Evidence.zip"
It was an attachment. I couldn't open the .zip file on my phone so I had to creep the office room and fire up my laptop. After installing Wickr for the second time, I was able to download the attachment and open it. A horrible sinking feeling started in my chest.
It was a collection of pictures; screenshots of all my text messages to her, screenshots of my PayPal payments to her, and pictures of eight different pairs of panties, and several pairs of socks. I recognised three pairs of the panties. One was the original pair I jerked off into, the second was the pair she handed me in person, and the third was a pair which came through the mail last week addressed to me, encrusted with the dried juices of her lovemaking. I did not recognise any of the others.
"What is this?" I typed into the chat.
She took about 25 minutes to respond, because of which I nearly fell asleep at the desk with the screen open.
"Those files r my backup so we r clear of wat is at stake if u stop doin wat I say. Theyll go str8 to ur girl, to all my WhatsApp contacts, all on Fb, insta, everywhere x."
I swallowed my panic and decided to be direct and calm.
"I've paid you what you've asked without question, what has provoked you to threaten me like this?"
Another delayed response, but not as long.
"Not a threat, just a reminder. And I dnt want any more money 4 nw. I wnt sumfin else."
The fact that she hadn't included what else it was that she desired really boiled my blood. I couldn't tell if she was really that dense or if this was all part of her sick game.
"What is it you want then?"
An immediate response: "Pictures x"
"Pictures?" I ask her.
"There wil b another set of my underwear comin thru the post 2moro or day after. Sealed them in zipped baggie, so will keep fresh. I wnt pics or a vid of u wankin with them."
The prospect of wanking myself off my freshly cummed in panties didn't exactly fill me with joy. Yet, there was a tingle...
Uch, no, what was I even thinking?
"Why?" I asked.
"I thought u liked wankin off in my panties? I wanna c wa u do. U got 24hrs to send a pic via Wickr or I upload the zip file. Sweet dreams xxx"
I sent her a final message saying that her demands were ridiculous - why would she even want such pictures? - but she did not respond to it.
I was happy to find out that Wickr was lockable with a password, so at least my correspondence with Shannon had just got a lot safer. I was massively concerned about sending her pictures, however. It did nothing but fatten her pile of evidence against me.
The next morning, the parcel came. I studied the hand writing on the front, which wasn't very girly. I got a bit suspicious about who had sent the package. It was pointless, of course, as I'd never ever seen Shannon's handwriting.
I stashed the parcel in an old travel suitcase until my girlfriend got up and went to work, at which point I hastily dug it out and opened it. Inside, as promised, was a zip-locked sandwich bag with another pair of silk panties. Emerald green. I guess a girl had to have a favourite colour.
I opened the baggie and slid out the panties, hooking them around my fingers and pulling them open. The inside was still damp and the gusset was kinda stuck together. It could have only been Nick's load which had slid out of her as she wore the undergarment.
Sighing, I put them on the kitchen counter and unzipped my jeans, thinking that I might as well get this over with. I imagined how the panties ended up in their current state. Despite everything, the thought of Shannon being pumped full with a load of cum got me instantly hard.
Careful not to get any of Nick's juices on me, I hung the panties off my erect cock and took a picture. Laying them back down, I came over the front of them much quicker than I could have imagined. The thought of all that cum trickling out her into her panties as she went about her day sent me over the edge in ways I'd never thought possible. I took a second photo, this time of my own cum spattered over the front of the garment.
I sent both pictures through Wickr as requested. When she didn't immediately reply, I popped the used panties back into the sandwich bag and stashed them back in the old suitcase. This was the fourth pair of hers now in my possession; I was slowly running out of places to put them where my girl wouldn't find them. I didn't dare throw any out, incase Shannon's instructions involved sending some back or something like that.
It was past noon by the time I had a response.
"Good boy. Bt I wanted pics of u actually using them, nt jst a b4 and after pic."
A minute or two later, another message followed.
"Itll do 4 now. It showed u will follow my instruction. Jst rememba 4 nxt time, I expect more x"
Next time? Fuck! Would this ever end?
"Thanks" was all I could manage in reply.
The kiss at the end of the message perplexed me.
"I'm comin over ur place l8r btw," she replied.
