Marcus' eyes slid over Seras' body as she began to squirm.  Whether he understood her true intent or not --- to show him she wasn't entirely helpless --- he grinned at her efforts and tightened his grip.  Her squirming, instead of giving him trouble, ended up shockingly working him all the way inside her body as the plant's lubricating paste eased the passage for him.<br/><br/>Though he grunted at that sensation, he then bared his teeth in something more than a grin, and pushed himself completely against her.  Though he let go of her waist, still he held her wrists down from her body, restrained.  She had expected him to dominate her in this hot, slimy prison, and he intended to, whether she was open to it or not.<br/><br/>He began to work his hips, the slime already making his thrusts smooth and deep within her, and he brought his face to hers.  He ended up pressing his bearded chin against her throat, and his teeth slid along her windpipe, not biting so much as nibbling... as though he was ready and willing to rip out her throat if she succeeded in fighting him.  He intended for Seras to know, and<span style="font-style: italic">feel</span>, that he was the one in control here.<br/><br/>With a loud growl-like sound, he started suddenly bucking harder, his upper body crushing her breasts and the force of his actions making the outside of the plant bulge with a sudden rhythmic frequency.  A few startled voices echoed from outside, though as the seconds passed the surprised sounds seemed to change to amused ones instead.  Trisha and the others had heard Seras say it was a man... so it wasn't hard putting the equation together.<br/><br/>"Need a little more time in there?"  Trisha's voice came, muffled, through the sides right near Seras' head.  She actually felt a hand spank her ass through the plant, not hard enough to hurt her but hard enough for it to be clear what it had been.  Marcus' teeth bit down a bit on her throat, as if he didn't want Seras to answer the question.  He was still thrusting, apparently having relieved his male urges enough in the last few days that it wasn't going to be one of the typical two-minute affairs most of the clan's men managed.<br/><br/>However, Seras would realize that in his frenzy, he was very slowly pushing her downward along the slick inside wall of the plant... easing her deeper into the sweet-smelling ooze.  It was up to her navel right now.
