A curious couple welcomes a third, a sleek silver vibrator, into their bed. She traces its smooth lines with her tongue, her eyes locked with his. He watches, entranced, as she parts her lips, inviting the toy inside. It hums to life, her moans filling the room. He joins in, his cock sliding against hers, their bodies moving in sync. The vibrator wanders, exploring every sensitive spot, driving them closer to the edge until they tumble over, gasping and spent.
