Randy was sitting at his desk working on an assignment on his computer and listening to his headphones. What he didn't notice was a small flash of light by his window above a plant sitting on the window sill. A small portal had opened and a few drops of slime had fallen in to the soil and began to merge with the plant. This was your basic green leafy house plant that he kept in the window.
Suddenly the plant began to grow a little, the vines had started to reach out as the base began to break apart the pot it was in. Randy had his back to the window and with the headphones on he could not hear anything. One of the vines had started to reach out for his chair, it slowly wrapped around the base. Suddenly Randy chairs was being pulled away from his desk and spun around as the plant dragged him towards it. The headphones plugged in to his computer were pulled off his head.
"What the hell!" He said as he tried to get out of the chair but more vines shot out grabbing his ankles and wrists holding him down. "Holy shit! What the hell is this! Let me go!" He yelled out but the plant did not react. He struggled to get free but the vines had wrapped around the arms of the chairs tying him up. Randy began to think about every Sci-fi and horror movie he'd ever seen and realized no good could come from this. A larger vine sprouted out of the base and moved its way towards him. It stopped in front of his face and he could see and hear air, almost like the vine was sniffing around for something. It leaned closer working its way down his chest sniffing around even more. Soon it was hovering above his crotch and took a deep breath, when it did it seemed to stop and focus around that area. 2 other smaller vines came out and slithered towards his pants, they started to work together undoing his belt, they one wrapped around his zipper and began tugging on it while the other wrapped around the button forcing it undone. Randy felt very vulnerable as the vines worked his pants open revealing his boxers. One of the vines slither in to the whole in the front and wrapped around his waistband before pulling them down showing his dick to the large vine still hovering above.
Randy struggle even more as his fear began to grow in him. One of the vines began to lightly caress his balls and shaft, after a moment he began to get hard as he couldn't help but enjoy the sensation but was still very worried about what the plant was going to do to him. As he reached full erection he looked up and saw the main vine had started to change, the tip was starting to flower open revealing a red inner color like a rose, it actually slightly resembled a flower with a deep whole in the middle with a greenish goo dripping out of it. Randy watched for a moment still worried if this thing was going to bite his dick off, he still struggled to escape but to no avail. He closed his eyes as he prepared for the worst as the vine suddenly lunged down on cock. After a moment his fear began to change as the vine had begun to suck on his manhood. The green goo inside was working as a lubricant as it slid up and down on him in a rhythmic fashion. He started to breath heavy as the feeling became more and more pleasurable. One of the small vines curled up under his balls and gave him a light massage which felt incredible, after a few moments he couldn't take any more and suddenly shot a load up in to the plant while the vine continued tickling his balls. The orgasm was so intense he didn't think he could have cum so much in his life.
After the feeling subsided the plant let go of his cock and untied him as well but Randy just sat there for a moment before he noticed the plant beginning to change again. He slid his chair back it fell on the floor and seem to grow in size. He noticed parts of it had started to smooth out while at the same time it was getting taller. What looked like human arms and legs had begun to sprout out of it in a milky green color. Soon there was a very attractive green skinned woman standing there with bright red hair and lips. Some of the vines had merged with her skin so there was a vine and leaf pattern throughout her body. She had 2 large perky breast with dark green nipples.
She stretched her arms out and opened her eyes looking around before she saw Randy on the floor with his pants down. She smiled and said "thanks for the sample!"
Randy sat there even more confused than before. "Sample?"
She could tell he was confused when she responded with "I'm sorry where are my manors, I'm a Nymph, sorry if I scared you before but a lot of creatures don't give up their seed easily."
"Seed? Nymph?" He blurted out.
She got down on the floor with him and planted a kiss on his lips trying to make him calm down. She sat down in front of him and said "ok, like I said I am a Nymph, we are plant like creatures that feed off the seed of mammals from all different dimensions, by the way what dimension is this?" She asked.
