Sarah

After several more passes, slowly licking the outside of her pussy, I finally allowed my tongue to slip inside of her, and she moaned with pleasure. I now enjoyed the delightful combination of John's cum with Sarah's own juices. I pulled away for a moment to share my discovery.

"My god, Sarah, you taste so good. I knew I loved the taste of John's cum, but you're delicious too. Will you cum for me so I can taste even more of your juices?"

As I spoke, John began mercilessly pinching Sarah's nipples. She tried to fight him at first, but then gave in as I returned my full attentions to her dripping wet pussy. She was panting heavily now, and I knew it wouldn't be too much longer, but I tried to prolong her climax as long as I could. I plunged two fingers inside of her, gently pushing in and out as I licked and nibbled her clit.

As she moved ever closer to her climax, I pulled my fingers out of her and forced them into her mouth, and she eagerly licked them clean. I then brought my fingers back down to her clit, and began rubbing her quickly and intensely as I entered her with my tongue once again. I knew this attention, combined with John's continued pressure on her nipples, would quickly take her over the edge. It was just a few moments later that I was rewarded for my efforts as Sarah's pussy clenched around my tongue, she arched her back, and sighed with a huge climax, and I once again had the opportunity to clean her up, this time licking away mostly her own juices, with just a faint taste of John still lingering.

"Very good, Kaitlin," John said with a smile as I stood up. "I appreciate your attention to detail. Now, let's all get back to work, and try to remember what we've learned here today."

"Yes, sir," Sarah and I said in unison, smiling as we pulled on our clothes and left his office.
