Who has he collided with?

His Mother

Delia Doe had also not been paying attention to where she was going, similarly deep in thought. However, unlike her son, who was obsessing over his sister-turned-penis, she was more focused on important matters, namely a matter of finances. It was because of this she didn't notice the giant shaft before walking into it.

For a small moment, she didn't know what it was. Then, she began to see, to smell, to *taste* it, and all of a sudden she knew. This was a cock. Perhaps the biggest cock in the world, certainly the biggest she'd ever seen. It was barely comprehensible as genitals, the tentacle resembling an elephants trunk more than anything else. The thing that confirmed what it was was the unmistakable taste of pre-cum, dribbling from the rods tip.

She tried to tear her mouth away, but found no luck, as the penis was now squashing her against the wall. She was beginning to get a clearer view of it's starting point, and her eyes went wide as she realised who it belonged to. Her own son, John Doe, was standing there, completely naked, exposed to the elements with a 5 foot cock. It was then she realised something horrible, something that shook her to her core. He was smiling. Not a happy, cheerful smile. A sick, perverted smile, the kind of smile that betrayed a cruelty hidden beneath. All she could do was close her eyes as she awaited whatever inhuman change was to come.
