The fingers gripping his hair really did something for Eames. The force and the dimest helpless feeling that came with it - Eames was really not used to being the helpless one. His hands had remained on Swoff's arse until that point, gripping and holding him close in the same way he was being handled. His hands pulled Swoff closer, let him thrust forward into Eames' mouth, pushed him against his tongue as he tried to compensate for not being able to take Swoff deeper.
But Eames did have two hands.
Not that he had just remember that but the additional points of giving a blowjob weren't high on his list of priorities before. Now, though, he had hands that he could use for good.
One remained on Swoff's arse, the fingers of the other wapping around the base of Swoff's cock, covering the space his lips couldn't.
Now he was effectively jerking Swoff off into his mouth Eames literally trembled with pleasure.
Of course he was still very much in control, but Eames still enjoyed the thought that he could be in this position again and not be.
