Xyveris laughs, grunting with the exertion as his hands grip her hips and drives himself into her harder and faster.  The more he leaks into her, the more pleasureable it is.  "Your womb is perfect for me," he grunts out.  Knowing that she won't put forth any effort to run away he releases her with the other tentacles as well.  One sneaks up along her body, teasing her mouth with the tip of it while the other slides down to start tickling at her ass.  Both are seeking entrance, and to get it provided for them, Xyveris starts having the tentacles on her nipples nibble on them, stimulating her as much as possible.
