He sat in his room working on the formula he was devising. He was a chemistry student at the local college and needed this one thing to pass. He almost had it a couple nights ago but it killed his rabbit, so he got a new one. This time he isolated the component and smiled as he blended them. He looked out his window and saw the new blonde neighbor bending over into the trunk of her car in her shorty shorts.
He had eyed her since the day she moved in. she lived alone and as far as he could tell, no boyfriend or husband. He wanted to ask her out but she ignored him every time he talked to her. He watched her tight tank top bounce with every step, she had a nice rack on her. He went back to his formula and kept working.
He realized it was morning and looked at his formula and put some in a needle and tried it out on the rabbit. He sat back and watched as the rabbit disappeared. He jumped up and looked around the cage with a big smile as he grew more excited. He stopped and thought for a second, would it work on a human? He filled another needle up and shot it straight into his vein. he sat down as it rushed through his bloodstream and into his brain. The formula mutated a few things as it began to turn him invisible. he looked as he was now nothing more than clothes.
He stripped down and looked in the mirror, he was completely invisible. He had an idea to put to use. He noticed that the rabbit wasn't back to normal yet. He took a second needle just in case he changed again. He stood in his window as he looked into the blondes house and saw her. He decided it was time to go visit her sexy ass.
He rang the doorbell and waited as the door opened. Cassie opened it and looked around and stepped out as he snuck into her house. He stood in her living room as she came back in and he eyed her sexy body.
Her skirt was denim, short and tight as it showed her nice ass. Her top clung to her nice tits as they remained firm and perky without a bra. The light pink top showed them nicely and the two dark circles the was hard and making her sexy. She went into the kitchen as he followed close behind her. She stopped and turned, she looked around as he sniffed her perfume. he was going to enjoy her.
She continued into the kitchen and put her dishes away. She bent over and he saw her skirt slide up and show her pink thong. He smiled at her tanned ass cheeks. He was waiting to nail her as she cleaned up. She stood and did a few dishes as he turned on the sprayer and aimed. Cassie let out a startled scream as it soaked her thin top and the front of her skirt. She looked as the cold water made the shirt cling and show her even harder nipples.
"Damn thing." She said wiping down with a towel.
She walked down the hall and into her bedroom. He followed and walked in as she peeled it off and revealed her perfect tits. He smiled as she let the skirt drop and showed her nice ass cheeks. He was horny as hell as she bent over in front of him. He needed inside her and crept up behind her.
She stood up and felt a hand on her hip as it slid down. She looked as her thong dropped to her ankles. Cassie stood froze as the hands slid up and around her flat belly. She gasped as they found her tits. Her eyes widened as he fondled her firm breasts. She felt his dick on her ass and realized what was going to happen.
He then grabbed her long blonde hair and pulled her head back as his other hand rubbed her nice pussy. Her eyes widened as he fingered her fast making her wet. He had her pussy well lubricated as he made the next move. Cassie was bent over and the cock rammed into her and began to fuck her tight little hole!
