Now imagining past!Jon trying to coax future!Jon’s cock from its sheath. Rubbing and mouthing at it, slipping further and further into his mouth as it emerges. Fascinated by the weight and feel of it in his hand, on his tongue. He wants it. He wants to have it. Something about the build of this future!Jon, the shape of them, not just their cock in its sheath but the eyes and fur (magnetic tape?) and the spines, the way they can hide their chest, how impossible it is to gender them one way or another… he longs for it.
