It took a little experimentation for Evie to find the motion that worked best - not that anything felt bad with Sam inside her and his hands on her breasts. Finally she settled on an up-and-down movement, with her hands braced on his shoulders. His cock rubbed her in just the right spots. She felt herself going higher, tighter than ever before.
When Sam took one hand off her nipple, she almost cried out at the loss. She watched him lick his index finger and wondered what he was about to do, though she was so caught up in fucking him she really didn't care. She was close, so close to her climax, and she trusted him implicitly.
He reached behind her and placed the tip of his finger on her anus, pressing it just a tiny bit inside the tight opening.
Evie gasped. "Sam?"
"Do you like it?" he rasped.
