You started to audibly moan and arch your back even at the lowest setting, it was enough to make you go wild. He moved up to kiss your neck while you writhed in pleasure, leaving it peppered in hickeys. With his other hand he unhooked your bra and slid it over your arms which were still pinned behind you, placing it by your discarded panties. He groaned and bit his lip, massaging your left breast as he rubbed the vibrator up and down your pussy. He was totally getting off to hearing your moans, which kept getting louder and louder.
“Oh god Mettaton, that feels so good, p-please don’t stop” you moaned out like so needy you were almost embarrassed. You were completely heartbroken as he suddenly pulled away from you. Hand, lips, vibrator and all.
“Mettatooooonnn whyyy!” you cried out looking at him with puppy eyes. “I had explained to you that I was going to punish you, didn’t I? He growled, tossing the vibrator to the side and taking you by your arms, pulling you up and over him, leaving yourself laying across his long legs. "W-what are you doing?” You asked with a shaky voice, with no reply from him but a low chuckle. You jumped at the sudden smack to your ass and yipped in pain at the metal making contact with you.
He was fucking spanking you, and you liked it. You loved it. “Punishing you darling, remember? You need to be taught a lesson for being so lewd.” He replied to you finally. He chuckled again and rubbed the spot he had hit in effort to comfort you, before smacking you again. You bit your lip to contain the moaning you were emitting but you still let some sound slip out; and you knew he heard it. You could almost feel the grin on his face burning down on your back, defenseless and completely under his control. Powerless. He knew you loved it.
