She pressed down as hard as she could on his cock when he warned her he was about to cum.  His cock stiffened, spasmed, and the first hot spurt of his potent sperm jetted hard into her cervix, triggering her own shuddering orgasm.  Feeling the wet heat of his cum pulsing into her was the most intensely erotic thing she had ever felt.  Made even more intense by the fact she wasn’t on any birth control, and the pregnancy risk was very real.  If anything, the thought of that risk only made her cum harder…

Love the image. The text isn’t bad, either.
