I discovered Michael's penis was slowly penetrating deeper into Betty's vagina with each thrust, each one deeper than the last.
Initially, it was halfway, then three-quarters, and finally almost entirely.
With a crisp snap, Michael's hips finally met Betty's buttocks with no space left between them.
At that moment, the sound echoed as Michael stopped thrusting, pressing his hips tightly against Betty's, his penis fully nailed into her.
At this point, Michael's glans had penetrated deep into Betty's womb, the very place of life's inception.
From behind, Michael's penis was no longer visible, completely enveloped by Betty's vagina, with only his testicles hanging close, his scrotum resting against her vulval entrance.
"Ah...Ah...Ah..." Betty's head threw back in a desperate scream as Michael fully entered her.
