He pants, his face flushed with exertion. She shakes her head, unable to form coherent words as her orgasm ripples through her body. Her muscles clench around him, milking every last drop of release from his aching cock. As the spasms subside, she collapses limply onto the bed, gasping for air.

"I-I'm sorry..."

"Huh?"

"Oh."

It's true; they've been having unprotected sex this whole time. The thought makes her heart race even faster, but not because she's worried. If anything, it fills her with a sense of hope and anticipation.
