Once she caught her breath, Tabitha strode purposely from the bathroom, through the bedroom, and down the stairs, leaving damp footprints on the wooden floor. Quietly down the basement where she found Rick engrossed in his notes, several scientific books open on the table around him. Without a word she walked up behind him and wrapped her arms around him, pressing her body against his gooey form.
"I need you inside of me," she said into his ear.
Rick turned around and looked at his wife, and saw the hunger in her eyes. Her wrapped his arms around her and their bodies pressed together. He could feel the wet heat from between her legs. Rick no longer had a penis in the traditional sense, and Tabitha had seen his Ken doll shape earlier. But Rick like his hands and feet, his semi-liquid state was capable of a certain amount of shapeshifting. He pushed Tabitha against the nearest wall and his body against hers.
Tabitha felt Rick enter her. Not in the normal way. It was something wet and warm and filling her in a way a penis could not. It was so alien yet she had no desire for it to stop. Deeper into her and then... Tabitha tried to scream out with pleasure but Rick's slimy lips met her and his slimy tongue entered her mouth. She could feel the goo from Rick's mouth dripping down her through even as it filled her vagina, pulsing and pressing against her G-spot impossibly well. Her screams of pleasure were lost in Rick.
Tabitha was putty in Rick's hands. She felt physically weak, warm and wet all over. Then she felt Rick climax into her, and the wave of pleasure and goo caused her to black out.
