Rupert knew he was being rather cheeky with Fred but he couldn't help it. She was so adorable when she got flustered, a trait Wesley had seemed to have picked up from her. Besides, he didn't see the problem with teasing either of them. They were lovers - at least when they were together.
The first time it'd happened was after Regan's disappearance. Rupert had came to Los Angeles to help find her and somehow all of them ended up in bed. It was obviously Wesley and Fred had needed something more to ease their pain and Rupert, who was feeling dejected over not being able to help more, wanted to offer them some sort of solace.
Afterwards, they talked and decided what they'd done had been a good thing. But they also decided they still needed to live their own lives. That didn't stop Rupert from feeling the way he felt. He loved the both of them very much and they were friends first and foremost.
He watched Fred and Regan disappear down the stairs before glancing over his shoulder. Martin had already went to take a shower and Rupert grinned before he turned to look at Wesley again. Reaching down, he took the other man's hand and tugged him into the bedroom.
"I've been wanting to do this for some time now," he murmured before capturing Wesley's lips and deeply kissing him.
