[you left before I could ask if this is okay, so I'm really really hoping it's fine if I adlib this]
Reed couldn't help smirking when Emerson gasped, and he continued to just play teasingly, pretending to think about undoing the button on his pants. His eyes were watching Felicia as the creamy skin of her decollatage was revealed. How he loved boobs.
When Emerson bit at his neck he moaned, and then he felt Felicia's hand touching his. He squeezed her hand briefly, then put his hand over the top of hers, continuing to touch Emerson but using Felicia and his hand to do it. He guided their hand to his side, then trailed their fingers back to his lower stomach. Reed's free hand had undone the button and pulled down the fly, and with their joined hand he moved it lower and lower, until Emerson's erection could be found. He closed their fingers over it.
