A/N: Sorry about the previous short chapter.
Two weeks later, back in New York;
"How was your mother son?" Edward Valmont asked Sebastian.
"Fine, fine father" Sebastian replied.
"Mother.." Kathryn started, Sebastian knew she was going to tell Tiffany about Matthew, of course she didn't know.
"Kathryn" Sebastian warned kicking her under the table.
Kathryn let out a yelp before continuing. "Australia is lovely Matthew was sure to show me around"
"Matthew? Who's Matthew?" Tiffany questioned.
"You didn't know mother? Matthew is Sebastian's twin brother"
Tiffany gasped at glared at Edward.
"Tiffany dear, Matthew lives with his mother in Australia and I really thought there was no need to tell you about him" Edward quickly tried to explain.
"No need? No need to tell me there's another Valmont?" She spat at Edward. With that she got up and left the house.
Edward stormed off afterwards.
"Why'd you do that Kathryn?" Sebastian asked.
"You deserved it" She said.
"Why may that be sis? I didn't go fucking your brother" He snickered at Kathryn.
"No, because if you did that would make you gay" She sneered at her step-brother.
"You don't even have a brother" Sebastian said.
"Not that you know of anyway Valmont" Kathryn brushed her hair back. "Don't worry Valmont I don't" She smirked.
"Sebastian" Kathryn called from her room.
Sebastian submerged from his room and entered Kathryn's.
"What do you want Kate" Kate, he called her Kate again.
She walked up to Sebastian and planted a firm kiss on his pouty red lips.
"What was that for?" He asked her, surprised.
"Sebastian I'm sorry" Sorry, Kathryn said sorry.
"Sorry?" Sebastian asked.
"Don't fuck with me Valmont, you heard me" She started to get angry.
"Sorry for what?"
"For fucking Matthew" She kissed his neck "I felt guilty"
"Kathryn Merteuil, guilty?" He questioned laughing.
"It's not funny Valmont"
He held her close and kissed her on the lips. "Kathryn I love you" He whispered as he placed on her on the bed.
"Sebastian I-I" Kathryn said before Sebastian silenced her.
"I know Katie, I know" He moved his hand slowly up her dress as she started to take off his top.
Sebastian pulled down her panties and rubbed her clit. "Mm" She moaned. "Fuck me Sebastian" She told him as she un did his pants. Sebastian's erection grew at those words. By the time Kathryn realeased his hard on he was ready. Sebastian entered her slowly. He let out a moan at the surprise of how tight she was. She felt good around him, she was warm. "Don't be a pussy Valmont, I'm not one of your virgins" She told him pulling him down for a kiss.
Sebastian increased his speed and pssionately kissed her, his hands wandered from her breasts to her hips where he grabbed her. Kathryn rolled him over so she was in control. "I want to ride you Sebastian, your to pussy to fuck me how I want" She smirked. He grabbed her neck and pulled her down and kissed her cheek. "Ride me Kat" He told her thrusting his hips upwards.
Kathryn's face was flushed and she was moaning and groaning. She was almost at climax. He muscles tensed and she tightened more as she came. "Ohh Sebastiannnnnnnnnn" She let out. Sebastian felt her come and he follwed. "Oh fuck Kath-rrrynn" He released.
Kathryn got off him and layed beside him. She was exhausted. Usually she could last 2 or more times with others. Not Sebastian he was good. Kathryn placed her head on his chest and listened to the steady beat off his heart and he played with her hair. "I love you Katie" He whispered before she fell asleep.
Kathryn awoke earlier then Sebastian. He had got a good nights sleep. Usually he would toss and turn and wake up during the middle of the night, but she had not felt him wake up. She went to his bathroom and looked at herself. Sebastian appeared behind her kissing her neck. "Sebastian" She smiled, not a fake one a real one.
"Your hair is everywhere, your hips and slightly bruised, your make-up has gone and you look so exhausted" He told her.
Kathryn's smile soon turned into an angry look.
"But, you still look as beautiful then ever, maybe more" He turned her around and kissed her cheek.
Sebastian turned on the hot and cold water of the taps on his bath and filled a bath for Kathryn. She got in and gestured for him to join her.
"I can't" Sebastian said.
Kathryn pouted. "Why not?"
"I have things to do" He said.
"You don't have time for me?" She questioned.
He shook his head. "Not right now Kat, I want to go to the mall and buy you a new dress. Size 4 right?" He smiled at her.
She nodded her head and kissed her Sebastian on the cheek before he left.
Sebastian got into his car and went down to the mall to buy Kathryn a dress she said she was going to buy, but Sebastian wanted to buy it for her.
He walked in and picked out the Royal blue and gold dress that he had seen her look at. "This one please" He gave the size 4 dress to the lady. He payed for it and returned home to his Kathryn.
When he got home she was awaiting him in her bedroom. He passed her the dress and she straight away put it on.
"Thank you Sebastian" She said.
He kissed her on the lips. The dress soon came off followed by moans and groans of Sebastian and Kathryn.
