The morning after I awoke as Cassie started to stretch her naked body beside mine. Her eyes futtered open and smiled warmly. We talked for a while as both got up. I slipped on my boxer shorts as she slipped on a nightie, flimsy and only just long enough to cover her pussy. We both mused about our display last night, as we were both aware that Mark and Tayla had seen a good portion of it. That turned Cassie on as she wondered aloud if they had fucked last night too. I'm pretty sure that any male who witnessed Tayla's near nakedness and then watched two people do what we did, would have fucked Tayla's brains out. Cassie kept the thought going by wondering whether Mark had a big cock like mine, and if he would play around in our love triangle. The thought was curious to me, I had always just had a one dick fantasy repertoire, so was unsure how it would work.
We both went out to the kitchen to get a coffee to get the morning rolling. As we waited for the coffee to brew, Cassie leaned against the kitchen counter, which brought her nightie up a fraction, just exposing her pussy. This never ceased to get my blood flowing, and I contemplated turner her around and pushing her over the counter and fucking her from behind. She caught that look in my eye and held the thin material at her waist, and groped it into a fist, pulling the material both upwards and exposing more of her slit and mons pubis, and also pulling her neckline down and exposing her nipples. Her demure look of false innocence had me reaching for her until we heard Tayla's bedroom door open.
Mark and Tayla emerged with tired and smugly guilty looks on their faces. As they smelt coffee, they joined us in the kitchen. Cassie released the material in her hand, letting her nightie return to covering her bits. It was still dangerously close to exposing her moistening pussy. Tayla was also wearing a favourite nightie that matched Cassie's in both flimsiness and shortness. Mark didn't know where to look as both girls gave each other giggles and nudges. Mark just gave me a grin that said all it needed to say...they had fucked last night and he was the happiest man on earth.
