After what seemed like an eternity, she slumped limply against me, like a rag doll, shaking. When she could finally draw breath, it came in ragged gasps. I just continued to hold her tight, and gently kissed the sweat slicked slope of her neck. My cock throbbed inside her, filled with a burning need for release.
