When she got outside she was glad to find that the bus was just pulling up to her driveway.
Jen sat in the back of the empty bus, she was the only person on this route besides her best friend Amy. After a few minutes she began to fell a pain in her behind. She had always hated all the bumps on her road and not they were causing her pain.
She rubbed her behind to try to ease the pain. The curious thing about it though was that it was not her ass-cheeks that her but down her crack.
Her ass-hole felt like it was trying to push itself out. She ducked down behind the seat to get out of the bus-drivers view and quickly took off her skirt. suddenly she felt a rush of pain through her ass that felt like someone was trying to push her but-cheeks apart. Her abdomen convulsed as if she we taking the largest sized dump ever known. She fell to the floor as whatever it was that was pushing out of her ass strained against her thong, making it dig into her private area. The thong mercifully snapped and was left dangling from her waist as tears streamed down her face from the pain.
The pain finally abated and her stomach muscles calmed down, but her ass still felt weird, like something was wedged between her ass-cheeks. Still kneeling on the floor she twisted around and was shocked by what she saw.
Growing out of her ass was a giant spider's abdomen! It was a glossy pitch black with a large red hourglass mark on its underside. Her cheeks actually looked a bit thinner as if they had shrunk somewhat to accommodate, but still looked just as sexy, being pushed out by the abdomen.
She reached out her hand curiously and was surprised when she felt her hand touch it, and it curled in response to her touch. Just then the bus hit a particularly large bump catching her off-guard and the impact caused a stream of web to shoot out! She touched it still in awe of her new body part. It felt stronger than steel as it stuck to to the buses wall.
How the hell did this happen?
