Tarn bites down on Sixshot's throat to keep himself from crying out as the Phase Sixer buries his chord inside him. He can feel the small knot at it's base stretching just inside the rim of his port.

He finds himself unable to contain his whine of pleasure when his partner begins to shallowly thrust inside him. It's so much and not enough at the same time and it is driving Tarn insane. He pulls away to lick up the rivulet of energon spilling from the bite mark, panting hot air against his plating.
