Erica and I awoke exhausted on the Friday. It had been a crazy week of sex, with Erica being hornier than I'd ever known. This was in no small part down to the part played by her two friends and work colleagues, Rhea and Helen. Erica had been incredibly turned on by my first week of sex apart from her, where previously we'd had threesomes only when we were together.
Yesterday's photo, sent by Helen, who had been slightly more reserved for most of the week, of herself and Rhea on their knees with my cum all over their faces had led to a night with very little sleep for Erica and I, as repeated photos, and a video, of Erica's face covered in more and more cum through the night were returned to both of the other women.
This morning, though, Erica quietly climbed on top of me and rode my cock until we both orgasmed, enjoying just quiet, intimate sex before I headed to my course and she went to work.
"Last day with the girls today," she commented afterwards. "Any special plans?"
I chuckled, "Not that I know of. Hopefully Helen will fully participate today. Or maybe even the two of them will try a bit together. Rhea did kiss Helen on the pussy yesterday, before I think they both got a bit nervous."
"Mmmm I'd like to see you fuck Helen... Fingers crossed!" Erica laughed, "You never know. Maybe they've had enough of you and will go straight home today!"
I laughed and kissed my beautiful, wonderful wife again. "We'll see! Anyway, we better both get up and dressed!"
Sitting down at the desk which had become our usual, I watched with pleasure as Helen and Rhea entered the conference room together. Rhea wore a white blouse unbuttoned to show the top of her chest and a different tartan skirt to the one she'd worn earlier in the week, showing a generous amount of her toned, tanned legs. Helen, on the other hand, was wearing a summery white dress with red flowers which came half way down her thighs and again showed a tantalising amount of the top of her chest.
The pair sat down on either side of me and I took the opportunity to glance at both cleavages as we greeted each other. We were a little early, and nobody else was sat on this side of the room yet, so Rhea felt no qualms in asking about the previous night.
"You two must have had so little sleep last night I don't even know how you're here. Was it six pictures you sent? How do you even have that much cum?!" she asked.
"I had to turn my phone off! Jason was getting really pissed off at my phone vibrating. I think I managed to calm him down though. I let him recreate the photos," Helen grinned. "Not that he knew about the photos of course!"
"Five photos and a video," I corrected. "And we went again this morning. Erica was really turned on by the picture you sent yesterday."
"Glad to be of service," Helen chuckled. "This week has done so much for my sex life I'm glad to return the favour a little!"
The chat turned to more mundane topics as more people arrived for the course and began to sit nearby. The course itself was deadly boring, completely repeating activities we'd done on previous days except for a short "test" towards the end of the day, although at least we weren't moved around the room to work with different people today, so I was able to enjoy the pleasant views of Rhea and Helen, sat between the pair all day. Erica had been right that the course wasn't really designed to be 5 days, and the extra cost of the two further days of the course was merely to make money, rather than for any extra content.
Unfortunately, our conversation for the day, after the first one that morning, was also limited, as a couple of other teachers sat very close to us and were very talkative. Two lovely older ladies, but definitely not people with whom to discuss what I hoped we might have planned for later!
Still, despite the boredom of the course, I found myself getting excited as the end of the day drew near. Scenarios ran through my mind as I wondered would I get to have sex with Helen today? Would it be the same as the previous day? Would Rhea and Helen interact with each other a little more? Or a lot more?! Rhea daring a kiss on Helen's pussy yesterday, although it had gone no further between the two at the time, opened up lots of possibilities!
Sure enough, as with every other day this week, Rhea and Helen were already packed up and ready to go the moment we were dismissed. I enjoyed watching the pair leave as I slowly got my stuff together and waited until very last again before thanking the course leader and leaving myself.
I headed to the toilets, and seeing neither Rhea or Helen outside, went straight in. Unlike the previous day, when I was hit by a whirlwind of kisses which soon became a blowjob from Rhea, all was quiet. I checked the cubicles, but nobody was there. Disappointed, I decided to wait. Surely they'd have said something if they'd had to shoot off? I waited ten minutes, becoming more and more disappointed as I realised I was waiting in vain. They weren't coming. A strange thought occurred to me that Erica would be disappointed too. She had been intrigued to see if Helen would fuck me today, and beyond excited at the prospect that Rhea and Helen both might loosen up their attitudes on being with other women. Erica had tried before to get Rhea to join us for a threesome, and had hoped she would agree if she went a little further with Helen today.
A real disappointment sat in my chest as I gave up. I even chanced a quick glance into the women's toilets as a last resort, but Helen and Rhea had definitely left. Helen's car, which the pair had been coming in this week, was gone from the the car park when I left, finally confirming my week had ended with a whimper.
The car drive home was twenty five minutes wondering if I'd done something wrong, wracking my brain for anything I might have said during the day to put the pair off. Unable to think of anything, eventually I had to assume they just had decided against it today. Their choice of course. I was just disappointed... who wouldn't be!
I was cheered when I arrived home and Erica's car already sat on the driveway. She must have left work the very moment she possibly could to be home at this time. Despite my disappointment, all I really ever need is my Erica. The others are a bonus, for me and her!
Opening the door, I wandered into the empty kitchen, then shouted my wife to find out where she was.
"Up here," came the reply and, kicking off my shoes, I climbed the stairs and opened the door to our bedroom.
The sight that greeted me gave me the fastest erection I think I've ever gained. Erica, my red headed, slim, beautiful wife sat coyly at the far end of the bed, clearly not long home from work, in her green blouse and a knee-length black skirt. Either side of her sat Helen and Rhea, grinning at the surprise on my face.
Erica smiled at the look of shock and delight on my face before, kneeling forwards, she came towards me onto all fours, crossing the bed without a word. She reached for my belt buckle and quickly undid it, before pulling my jeans and boxers down around my thighs, releasing my eight inch erection. Looking up into my eyes, she leaned forward and immediately took me into her mouth, licking all around my cock as she bobbed her head along the shaft.
I reached along my wife's body as she sucked, taking hold of the hem of her dress just above her knees, and pulling it up to bunch around her waist, giving the other two women a view of her arse and pussy, covered only by a pair of small white panties. Without hesitation, I began to run two fingers up and down her pussy over her knickers, able to feel she was already wet and very horny.
Helen and Rhea didn't wait long, Rhea acting first as she scooted down the bed and knelt next to Erica, leaning forward in the same way and observing, for the moment as my wife sucked along my cock, before releasing it from her mouth and shifting it towards Rhea. My wife's Teaching Assistant wasted no time in joining her, wrapping her lips around the head of my erection and running her tongue over the tip as my wife kissed her way to taking one of my balls into her mouth.
