Megan, meanwhile, was holding onto a shivering Stacy. Stacy had always been more emotion than Megan had, and now she was far more scared and cold than Megan was. Megan tried to calm her down, but was of no use, and Stacy sat there shaking in the dark. Megan was about to say something, when she felt something touch her ankle. She tried to look down at it, but with no light, she couldn't see a thing. She ended up feeling around for it, and felt a fleshy vine that coiled around her finger. Megan was about to tell Stacy about t, when a dozen more like it shot out of the dark and wrapped her up. They were squeezing her so tight she couldn't breathe or scream.
"Megan." Stacy asked. "What was that?"
Megan tried to scream out her answer, but a tentacle slithered down her throat as soon as she opened her mouth. On the plus side, however she was now able to breathe. Panic overtook her quickly once again, as the appendages started to move, and open up her arms and legs. As quickly as they could manage, one tentacle pushed itself under her clothing and into her cunt, while another dove into her ass. The first one pushed deeper and deeper until it hit her cervix and pushed that barrier as well. Megan was thrashing around, helpless in the tentacle's grasp. She started to cry as another tentacle pushed its way into her pussy, followed by another, and another.
Stacy was now completely frozen. She couldn't hear much, but the muffled cries of her friend were incredibly loud in the hole. She hadn't moved the entire time that all this was going on, but now she really was going to push her luck with the gang. She stood up and turned, trying to run, but she had made some noise in the process. It wasn't much, but the creature heard enough and shot out at least a dozen more appendages to encase Stacy.
Now that it had them both wrapped up, it seemed to take a more leisurely pace. It stopped squeezing as hard and pumping as hard. Stacy was having a much easier time breathing, but she didn't dare open her mouth to scream. The thing was actually waiting for her to open her mouth, but when she refused, it satisfied itself with pushing into her pussy. This time Stacy opened her mouth and let out a grunt of revulsion and surprise. The tentacle in front of her face slid down her throat and stopped nearly at her stomach.
The creature continued to fuck the two girls. Both of them knew they needed to escape, but as time wore on, and they came over and over, their mind were getting hazier and hazier. Eventually Megan gave in and willingly opened her legs to take more of the tentacles in. She felt the expansion of two more tendrils and started bucking in its grasp. When she had calmed down, her arms were released, and she grabbed the one in her mouth, pushing and pulling on it until it had removed itself as well. She coughed a few timed before sucking it back inside and bobbing her head up and down on it.
Stacy wasn't much different, once she had started to thrust against the creature; instead of away from it, she was released. She stuck out her ass and was rewarded with three tentacles entering her rectum, pushing as deep as they could. She finally cried out, only in ecstasy instead of fear.
For the next hour the creature fucked the two girls. They were in a state of almost constant orgasm, and hoped it would never end. Eventually, however, Megan started to fell the half dozen tentacles inside her swell slightly, and eventually they all started rhythmically pumping something directly into her womb. Stacy cried out from somewhere in the darkness when the lone one in her cunt finally pushed past her cervix and performed the same process.
After a while, Megan noticed her stomach was getting stretched and finally stopped when it was about twice as big around as it had been before. At the same time the tentacles also stopped, and slowly, one-by-one, pulled themselves out of her. She was laid down on the ground, and quickly passed out from exhaustion. Stacy soon followed, and the two girls slept there as the creature receded back into its hole.
