Couple of typos (sorry, the beta eyes never leave. feel free to screen this if you want.) "The whole matter awkward" should be "The whole matter /is/". Also "holds his cheek" should probably be "holds his cheeks".

Otherwise, this was LOVELY. Totally not my kink at all, but I absolutely adored the dynamic between Jack and Ianto here. I have a hard time buying Ianto as being completely willing and easily led to being submissive, so I really liked the way he's still sort of fighting it here, even though he knows it will be good for him. And the moment at the end was really sweet. :)
