"Looked like you had fun last night," Rhea whispered to me as she sat down. She was wearing a black and white checked skirt today, beneath a green strappy top. I couldn't help noticing she'd forgone the leggings today and had her long, toned legs fully on show.
I grinned. "Erica sent you that picture then? There's three loads worth on her. She refused to clean up in between. I think she wanted to remind you I'm hers before I saw you again today."
Rhea looked slightly worried for a second, so I continued, "If she had been pissed off about yesterday then a) I wouldn't have been fucked the way I was last night, b) she wouldn't have sent you a picture of her face covered in my spunk, and c) she definitely wouldn't have asked me for pictures if we get a chance to fuck today."
Rhea visibly relaxed and smiled. "We'll have to see what happens then won't we..."
A minute or so later, Helen came into the room and again sat down on the other side of me with a smile and a "Good morning." She busied herself taking out her stationery and settling herself until Rhea offered to get her a brew and disappeared into the venue's kitchen. "I can't believe you two!" she suddenly whispered to me, backhanding my arm. "I know you and Erica have an... unusual relationship, but... well I didn't really believe it I suppose."
I paused, not really sure how to respond. She could clearly tell I wasn't sure what to say and her face softened. "It's not like you're cheating I suppose. I was just... shocked. I don't actually think I'd have believed it if Rhea hadn't shown me the video Erica sent. And forwarded me the picture last night!"
Again, I was unsure what to say, so I merely smiled. "Was she honestly ok with it?" Helen continued. "I know you said you'd had threesomes but I'm pretty sure you said you'd always been together yesterday."
"We always had," I whispered back. "Yesterday was the first time Erica wasn't there. I'll be honest though, and I didn't say anything yesterday because I didn't want to offend anyone, but she told me before I came her in the morning she thought Rhea might have plans and told me she wanted me to see what happened as long as I gave her every detail after." I paused, "Sending pictures was Rhea's idea. Erica loved it though!"
Helen was blushing by now, and seemed unsure how to respond. She gave me the same smile I know I'd given her just a few seconds earlier, and was clearly a little relieved when Rhea returned with her cup of tea and the course leader soon got started, moving everyone to work next to people we hadn't been next to the previous day.
The course was just as, if not more boring than the day before. I spent a huge chunk of the morning daydreaming, and being me, that meant I spent a lot of the morning hiding an erection under the desk. At dinnertime, the conversation between the three of us was flirty, but as another couple of teachers had joined us, there were no direct questions or comments, which I was more than happy with.
The afternoon again involved us all being moved around, and I was working in a group with Rhea. The activities were simple and boring, and the three teachers working with us were as dull as dishwater, as well as clearly knowing one another. It wasn't long before I began daydreaming again as the other members of the group discussed sound buttons. Rhea was clearly bored too, as after a while I felt her hand rest on my left thigh. My erection soon grew under her palm, but she contented herself with resting her hand on it, not moving to avoid drawing attention from the other women at the table.
As the course leader ended the activity, and the day, Rhea gave my hard cock a quick squeeze before she again quickly stood and was the first person out of the door. I again slowly packed up my things, watching as the room emptied around me, before following out of the door.
Rhea and Helen were stood together in the corridor, whispering as the last couple of teachers walked past on their way out. As they saw me heading towards the men's bathroom, Helen wordlessly disappeared into the ladies' room while Rhea nonchalantly leaned against the wall, before following me straight into the men's.
She hit me like a whirlwind, lips pressed firmly against mine and her hands immediately unbuckling my belt. My hard cock was out and my jeans and boxers around my ankles within seconds as she knelt in front of me. Rhea wasted no time in taking me into her mouth, her right hand rubbing along the end of the shaft while her left cupped and fondled my balls. I enjoyed the warmth of her expert mouth and tongue for a couple of minutes, grasping her hair as she bobbed up and down on my erection.
Reaching down, I moved both straps of her top off her shoulders, and she obliged me by taking her hands from my cock to lower the top to her waist, before reaching behind her back to release the clasp on her bra, displaying her stunning, pert breasts.
Using the hand I had entwined through her hair, I gently pulled Rhea to her feet, a long strand of spit and pre-cum trailing from her bottom lip to the tip of my cock until she brushed it away. I spent a couple of second gazing at her beautiful chest before I lowered my head and took her left nipple into my mouth. She moaned gently as I ran my tongue lovingly around her areola, flicking it over the hardness of her nipple as I reached down with my hands to hitch up the back of her skirt, revealing a toned and pert bottom barely covered by a lacy thong. I fondled her perfect arse while I sucked and licked her nipple, Rhea's hands running over the back of my head and shoulders.
