"Erica wasn't happy last night," I whispered to Rhea. The Phonics course was just beginning the final session in the afternoon of the third day, and we'd been sat apart in the morning, placed in groups for the various activities. Whilst we'd sat together to chat during the break and dinner hour, lots of other teachers had stayed around this dinnertime so I hadn't had chance to mention the previous day. "She says if she doesn't get the photos I promised today then neither will you tonight."
Rhea smirked. Erica had sent just Rhea just one photo again last night, but had been careful about exactly what it was to include -- she'd taken a selfie of her face against the pillow as I'd fucked her from behind -- it was clear what was happening but showed no detail. The picture had been accompanied by the words -- 'If I have to use my imagination so can you!' and a winking emoji.
"I'm sure we can make sure she doesn't miss out today," Rhea whispered in reply.
I let a grin play across my own face, largely due to the fact that Rhea had just confirmed I'd get another chance to fuck her once the course had finished for the day. She was wearing a tight, white, strappy top today, which accentuated her breasts, above a khaki coloured pleated skirt which reached half way down her thighs.
Erica's other workmate, Helen, sat on the other side of Rhea this afternoon, and I had to confess I was more than a little disappointed I hadn't been sandwiched between the two as I had previously. Helen in particular was looking very attractive this afternoon -- her dark blue skirt seemed slightly shorter today than the skirts she'd worn previously and her toned legs had caught my eye the moment she'd walked in that morning. A pale blue buttoned blouse meant I didn't have quite the same view of her chest as I'd have liked, but from where I was I wouldn't have been able to get a great view anyway, so contented myself with admiring the tanned chest of Rhea between us.
As the course leader droned on, I wondered if Helen had mentioned to Rhea what had happened after Rhea had left the men's room the previous day. After Rhea had left to clean herself up, I'd investigated a suspicious noise and shadow I'd noticed beyond the cubicle door while Rhea had been riding me. As I'd suspected, Helen had listened in the cubicle next to us, and had finished rubbing herself to orgasm with the taste of mine and Rhea's fluids in her mouth. Rhea was deep in discussion with Helen now, although the whispers were too low for me to catch what they were saying. The discussion didn't last long, as the leader introduced a new activity which involved us all standing and moving around the room before we sat back down for the final quarter of an hour.
As the course came to a close for the day, I felt Rhea's hand rest on my cock below the table, as it had the previous day. With only Helen close enough to notice, who already knew exactly what we'd been doing the previous two days, I placed my own hand onto Rhea's thigh, inching up between her legs. Shortly the front of Rhea's skirt was bunched all the way up and out of the corner of my eye I saw her nostrils flare as my fingers began to probe at her mound, already wet with anticipation.
Surreptitiously I pushed her white panties to the side and continued to explore her wet pussy, Rhea removing her hand from me and leaning forward with her elbows on the table to ensure nobody further away could see where my arm was reaching.
Helen, however, was watching everything. Her face was towards Rhea's as they pretended to be locked in conversation, but her eyes alternated between locking with Rhea's and flicking down to watch as I slowly rubbed at Rhea's soaking groove. The angle, and of course the fact we were in a room full of other teachers didn't allow for rubbing Rhea towards an orgasm, so I continued to slowly rub up and down occasionally just grazing the clitoris, until the course finished and I slid the tip of one finger inside her.
