My first Theesome

She started to yelp as her orgasm approached. “Harder! Fucking make me cum!”
Rob started to slam into her and Clare began to scream. Her orgasm hit her like a steam train. She was bucking on my face in time to Rob's deep fucking. Over the sound of Clare, I heard Rob moaning heavily and realised he was cumming too.
Their bucking in time began to slow. The noise died down. Clare's body began to relax and Rob slowly pulled his swollen cock out of Clare's pussy. As he did, Clare begged at me, “Eat my pussy, make me cum again!”
As Rob's cock finally left her pussy and I was just getting to sucking her clit again, Rob's thick white load dribbled all over my mouth and tongue. Anticipating my disgust, Clare pushed down on my face and said, “don't stop! It's my favourite bit.”
I tried to ignore the salty taste of his cum and keep licking Clare's pussy when I felt Rob's mouth on my cock again. He was sucking hard and it resulted in my mouth working harder on Clare's juicy, used pussy. She began to grind and buck again. Her orgasm was building and so was mine.
Rob was going to make me cum.
As that thought washed over me, I felt the familiar tidal heave of the approach of my orgasm. Clare was starting to yell as her orgasm took over her. That spurred me to do the same.
I felt the release of cum into Rob's mouth without guilt. I was sure he was far more in control of this situation than I was. He sucked greedily on my cock until I'd finished.
Clare was panting heavily now as Rob stood and kissed her. I realised his mouth was full of my cum which was now running between her tits and down her belly.
It was inevitable.
My face was trapped between her thighs as my own cum ran onto my lips.
Clare retreated from my face and bent down to kiss me deeply. The kiss tasted of her pussy, as well both mine and Rob's cum.
She sat back up and gave a big sigh, “That was fun, huh?!”
I laughed nervously and said, “Well I've never done... ...any of that before. Can you untie me now?” A big smile on my face.
Clare laughed, “No. we're nowhere near finished with you.”
Rob turned and smiled at her as he bent over and retrieved a shiny red ball gag from the drawer.
