"Go ahead," Jack chokes out, and he isn't sure how he manages to get it out between everything he's feeling but he's not sure it matters, because he's so fucking close and one wrong-- or right-- move will have him spilling out all over the covers and he really doesn't think he cares too much. He's a big fan of mutual coming, though, so he slows their combined hands on his cock and tenses deliberately, clenching around Zephyr, and slowing down didn't really help at all because just that feeling, reemphasizing how warm and big he is inside him makes his whole body tighten and he's coming with a long, low moan.
