Excerpt anyone?
While his rigid cock glided within her, she perceived its burgeoning, pulsating shaft as it prepared to spurt his seed. His imminent satisfaction was quickly mounting as he panted and raucously moaned behind her. The head thumped against the threshold of her womb, sending shock waves throughout her lower body. Then he halted his movements, forcing it further inside while his seed exploded deeply within her. He cried out, then resumed his heated thrusts. His cock contracted inside her, continually spurting fluid as though his orgasm refused to end.

No comment needed. I feel like that should stand on its own.
