"Okay, guys, I have to go." said Yumi after returning to the gang after her and Ulrich's three hour make-out session. "Bye." they all said and she left.

Ulrich and Odd returned to their dorm. "Arghhh! Odd, I can't stand it! Yumi promised she and me would do it today!" Ulrich whined to his friend. "Okay, ew, too much info, there dude!" stressed Odd as he made a gagging noise.

"I can't stand it! I have to see her!" Ulrich said standing up. "Oh yeah, and face her dad, again? Last time, he almost strangled you!" Odd said remembering.

"Your right, but what can I do?" asked Ulrich. Odd looked up at him and then back down to his magazine. "Jerk off or something." Odd said as he flipped the page.

"Argh! That's not the same!" Ulrich stressed as he lay down on his bed. Suddenly, he sprang up. "Odd! Do you still have that lockpick?" Ulrich asked, even more excited. (lol.)

Odd looked at him in puzzlement. "Yeah, it's on my desk. But why do you need it." asked Odd as Ulrich retreived the lockpick. "Reasons." Ulrich stated simply and went out the door.

Ulrich walked down to the girls floor and avoided Jim as he was sleeping. Ulrich knocked on Sissi's door. No answer. He tried the doorknob. it was locked, of course.

Ulrich began to mess with the lockpick, and finally got the door open. He walked inside and found Sissi lying on her bed, awake with her eyes closed, listening to music. She had a nightshirt on, but thats about it.

Ulrich bit his lip and felt himself harden. He walked over to Sissi's bed and removed her headphones. "What the--?" Sissi got cut off as Ulrich fiercly attacked her lips. Sissi got wrapped up and placed her arms around his neck as she felt Ulrich's hand slip under her shirt and massage her breasts.

Sissi gasped and started moaning. Ulrich moved his lips from hers down to her neck, kissing and biting on his way. Sissi moaned harder and pressed herself against him and felt his hard-on.

Ulrich groaned and lifted her shirt off. Sissi blushed as Ulrich began sucking her breasts. She began moaning and breathing faster. Her nipples went hard and Ulrich got even more excited and his hard on ached.

Sissi reached for Ulrich's shirt and tugged it off and licked his chiseled chest. Ulrich groaned in response and pulled away from Sissi. He then lay her down on her bed and took off his pants.

He took off her panties and slowly inserted himself into her, coming to her barrier and breaking through. Sissi almost screamed out in pain, but Ulrich covered her mouth with his.

Several hours later, Ulrich and Sissi were lying in her bed breathing hard. "That was...amazing." Sissi breathed as Ulrich put his pants on.

"I always knew you loved me!" Sissi squealed. "Pff, yeah right," started Ulrich as he buttoned up his shirt and opened the door, "It was only for one night."

AN: Well, how was it? I think Ulrich enjoyed it, but now I have run from Yumi!

Yumi: GET THE HELL BACK HERE!

Me: AHHHH! runs.
