Rocking between fingers and vibrations she began to tremble. The bite had made her groan but mostly the sounds she made were small. She lost her coordination as she moved, the trembling of her muscles increasing until she stiffened, her mouth open, eyes closed as she came soundlessly. Wave after wave of pleasure crashed over her, her hips giving helpless little twitches.
Finally her muscles relaxed and she flopped down with far less control than she showed in anything except orgasm and post-orgasmic lethargy. "My God," she muttered in Welsh and lazily placed a kiss to the woman's shoulder, which was the nearest thing in range.
Conscious that there was still a vibrating dildo connecting them she forced herself to disconnect them and flop sideways instead. Thankfully she also flopped onto her wand and grasped it to finish the spell.
