For the next week Blaise and Hermione went to the library every day while Draco worked on his lessons and Theo did his training. As it was Blaise had been given a break and would finish his Auror training the next week.

It was Friday and Blaise and Hermione were once again at the library. Hermione was trying to get a book that was just out of her reach when someone else grabbed it. Hermione turned around to tell whoever it was that she was after it first when she saw Blaise standing in front of her holding the book out to her.

Hermione took the book and looked up at him. They were so close together. Barely and inch separated them and Hermione couldn't help but be enticed by Blaise violet eyes. Hermione bit her lip softly remembering the lust that had ensured ever since the rescue of Draco all those months ago. Blaise was looking down at her, lust in his eyes and all of a sudden he leaned down and kissed her passionately. Hermione dropped the book as Blaise pushed her up against the bookshelf and put his hands on her hip. Hermione wrapped her arms around his neck and kissed him back just as passionately. Soon buttons on shirts were being done and both teens found they were glad the librarian had left for lunch a couple minutes before, trusting them to not make a mess of things. Blaise carefully massaged her breasts as he kissed down her throat being careful not to leave a mark. Both knew this was wrong but they couldn't stop themselves.

Hermione pushed Blaise down onto the carpeted floor of the library and crawled on top of him. She kissed his lips and then made her way down his jaw and neck and the down his torso. When Hermione reached his pants she careful undid the button and took his pants off him. Blaise soon flipped her over and took her skirt of her. Soon neither of them was dressed in anything and they were making out passionately as Blaise pushed himself inside of her. A contraceptive spell was placed and then both were moaning as he rocked inside of her. In, out, in, out, in, out was the pattern in which they formed. Hermione soon grew tired of him doing all the work and flipped them over so that she was on top. Hermione carefully moved herself into a position where one of her legs was bent so that he was hitting her own sensitive spot and she found that it also hit his. After minutes of moaning both erupted in an intense orgasm and Hermione collapsed on top of him.

It took a couple of minutes for Hermione to catch her breath but when she did her eyes went wide and she quickly got off of him. Hermione dressed with lightning speed and Blaise soon followed. Both had finally realized just how wrong it was that they had just done that. Hermione walked over to the sofa she had been previously occupying and sat down. Soon she was in tears and Blaise quickly wrapped his arms around her. But Hermione pushed them off of her.

"I can't believe we just did that. If Draco finds out… oh god." At this Hermione cried even harder and Blaise sat there in a daze.

"I can't believe I just had sex with my best friend's girlfriend. Oh god." Blaise put his head in his hands and groaned. After a couple of minutes Hermione sobs turned into soft sniffles and Blaise turned to her. "Draco must not find out about this ok? There's no way he will unless someone tells him and we're the only ones that know. As long as Draco doesn't find out and this never happens again I'll keep my best friend and you'll keep your boyfriend."

Hermione nodded and slowly stood up. She cast a spell on herself so that you couldn't tell she'd been crying and to fix her makeup. She then took a deep breath and said: "I'm going home. I don't think we should be alone together again, ok?"

Blaise nodded and Hermione left the library. As she made her way home all Hermione could think about was how she had just broken Draco's trust. She had just reached the door of the penthouse when she came to her conclusion. She had to tell him…

When Hermione entered the penthouse she was more than nervous. She slowly made her way into the sitting room where Draco was reading. Hermione silently sat down beside him and he lowered his book, having sensed her nervousness.

"Hermione, what's wrong?" Draco asked in a concerned tone.

"I've done something awful Draco. I don't know how it happened. I wasn't thinking…" Hermione began.

"What did you do?" He asked, dreading the answer.

"I… I… oh god Draco I'm so sorry. I had sex with Blaise." Hermione said and then she burst out crying.

Draco turned away from her and closed his eyes. He was hurt beyond belief. His best friend and girlfriend had just had sex together, it was a major betrayal. A single tear leaked from his eye and made its way down his cheek before he quickly wiped it away. After a moment Draco turned back to Hermione and saw that she still had tears running down her cheeks except they were silent tears now.

"I don't know what to say about this. I trusted the two of you to not do something like this and then you two went off and did it. Hermione, I love you. How could you do this to me?" Draco said quietly.

"I wasn't thinking. It all happened so fast that neither one of us had time to think about our actions. I love you Draco and only you. Please believe me." Hermione replied just as quietly.

"I don't know if I can right now. I need some time to myself. I guess I can only be glad that you told me right away instead of having it so that I found out from someone else." And with that Draco went to his bedroom alone for the first time since Hermione returned.

Two weeks past and Draco and Hermione's relationship was still rocky. The two had been sleeping alone in their rooms the entire time and spoke minimally to eachother. Blaise and Draco's friendship was rocky as well. When Blaise had returned to the penthouse Draco had confronted him and punched him square in the nose. Since that moment the two were on testing ground. Although Blaise understood why Draco had hit him like that he still didn't very much appreciate it, but he also felt ashamed of himself. He still couldn't believe he had sex with his best friend's girlfriend.

At the moment Draco and Hermione were seated in the sitting room reading separately or at least trying to. The silence was getting to the both of them along with the lack of affection. It was getting to the point where neither could consentrate and finally it was Draco who broke the silence.

"Look Hermione, I've had time to cool and I think I finally understand why all this ended up happening. I understand that the living situation creates sexual tension and I know I myself feel it towards the other two every once in a while." Draco sighed. "I guess I'm just trying to say that I forgive you. Just, please, don't let it happen again because I don't think my heart can take much more pain."

Hermione smiled and went over to him quickly. "Thank you" and with that she kissed him full on.
