…Mel felt a strange sensation like if the black material was sucking her finger tip and was slowly crawling upwards. As her sister was wondering what was happening, Jenn was in heaven. The simple touch of her finger had sent powerful waves of pleasure all across her being but it had also allowed her to discover her new abilities. She now knew that she could change shape at will and contract or expand her body at will, allowing her to become a simple ball of latex that would fit in the hand or cover many bodies and wrapping them with her being. She also had full knowledge of her sister's most hidden phantasms and found them very interesting but she discovered a latent latex fetish that she wanted to bring up to light. So Jenn decided to go slowly first and conquer her sister with this fetish by playing and teasing her.
Melany pulled her finger up and finally the latex released it. She looked at her hand and at the black puddle. The touch of the latex had made her feel warm somewhere inside and she bit her lips as she hesitated. She had two hours of free time before her, perhaps she could play a little with this new toy. She was sure it was some kind of new sex toy her sister Jenn had found. She kneeled near the puddle and lowered her left hand until the palm touched the surface. She smiled as she felt the latex slowly join with her skin. It was warm and soft and this sensual contact greatly aroused Mel. The tingle in her lower belly was clear, this situation was making her incredibly horny and she decided to go for more.
She lifted her hand and once again the latex released it but it seemed to try to keep contact as long as possible. This idea sent shivers down the spine of the young woman who stood up and began to strip. Jenn looked at her older sister who was removing her clothes, she nearly came just at this though but used her will to remain calm. Soon her sister was standing bare naked just in "front" of her and Jenn was expecting for her next move.
Mel kneeled down in front of the puddle and got to all fours, she then came forward, walking in the puddle. Each "step" was rewarded by a thrill of delight as she felt the latex join with her hand or knee before letting it go as she crawled further. Jenn extended herself slightly to allow her sister to stand on all fours in the middle of her body. Mel had closed her eyes, her body shivering just as the though of the situation. She stood there for a while and opened her eyes to look as she slowly lowered herself. Mel's hard nipples reached Jenn's surface and the two sisters were overwhelmed by delight. The black latex covered them and began a light and sensual massage that Mel barely noticed as the contact of the latex against her nipples and breasts was simply too good. She continued to go down, more and more of her body getting contact with the wonderful material under her, sending shivers of pleasure in her.
Jenn felt great with her own sister lying on her belly right in the middle of her body and breathing deeply as she was discovering her strong latex fetish. Jenn decided it was time to help Mel to succumb to her new desires and began to alter her body while massaging her sister and crawling up slowly on her bare skin. First she removed all hair on her body except for her head, then she made her skin very soft and sensitive. This was nearly too much for Mel who moaned stronger as her sister finally encased her writhing body in her black material. It felt like soft hands where running all along her skin, massaging her in a very sensual way. It relaxed her but also made her even more horny and Jenn could feel the moisture between the thighs of her sister, revealing her strong sexual excitation.
"- well, it's time for more now…., thought Jenn. There was still a puddle of her own being under her sister despite the fact that she now covered her from head to toes, leaving only her eyes, nostril, ears, mouth and hair uncovered. She slowly pushed herself against the hot and moist lips of Mel's pussy and began to flow inside her. Mel threw her head back and gasped for air as this delicious intrusion inside her vagina was taking her to new heights in pleasure. She felt the black goo invade her, flow deeply in her and explore her most intimate parts like no one had ever done before. Jenn was greatly pleased by the moans of her sister and the fact of felling her heat around the part of herself inside Mel's vagina. She made it take the form of a large and long dildo, throbbing and was rewarded by the felling of her sister gyrating her hips while her pussy spasmed around her.
Mel was becoming delirious and wanted more even if the huge dildo inside her was making her fill full and stretched. She shoved her bottom up, spreading her buttocks with her hands. The message was clear for Jenn and there was still enough of her to pleasure her sister. She then made herself flow in the anal opening of her sister, going deep before forming a big plug that began to vibrate at the same time the dildo did. Mel could only shiver, mouth wide open as the pleasure ran through her body and exploded in her mind. She gasped for air, shaking from head to toes and suddenly yelled as ecstasy hit her. She fell on her back but her sister did not release her and continued to pleasure her body which continued to cum, more and more...
