This time".She pulled the towel away, releasing my desperately hard cock, squeezing it in her hand with a "mmmmm" escaping her moist lips.Needing no m...re encouragement, I moved between her thighs, and guided my hot member straight into her waiting cunt. "oh yessss" hissed Cathy as I left it still for a moment, allowing out sex to get accustomed to one another.Slowly, I pulled outwards, before gently pushing back inside, gradually building up a slow deep rhythm while she pushed her hips towards. Please let me do this for you... for us."Connie started to wiggle her bottom, rubbing her round globes against my cock, which was hard as a rock again. I could feel it throbbing against her luscious ass. I knew it would be weak of me to give in. I also didn't know if I was strong enough to say no."Oh, baby, I just don't..." Shhh, don't say no, Grandpa. Just be quiet, close your eyes and hold me... please."I did what she asked. I felt her moving - not leaving, just some sort of movement. One arm. James began her own portrait of Andrea as I added the finishing touches to mine. By the time the light began to fade on Saturday of the following week, I pronounced mine finished and signed T W Farris in the bottom left corner.Andrea was anxious to look but I put her off again, saying, "Why don't we wait until Mrs. James is done and we can look at both of them together?"Mrs. James scolded me. "Don't be so cruel, Terry! The poor girl has been waiting on pins and needles to see what you've done. So would you be able to perhaps, help me?" she asked.As she looked up, she must have caught me glancing at her big firm breasts, as when I caught her eye she was smiling and blushing like a red light. "Um, yeah course I would. How about after school? I’ll meet you outside the empty R.E classroom. No one ever goes there anymore," I said smiling at her. So as we continued with the rest of the school lesson, finishing up quickly. Lucky for us, it was the last lesson of the day. Ten minutes after.
