That groan, the way he could practically feel the heat from Peter's flushed face, that additional, wholly deliberate pressure, it was all just too much for Thor hips rolling upwards once more and hand tightening against the back of Peter's neck reflexively as his pleasure broke.

The orgasm that rolled over him, swept through him, was enough to leave his thighs shaking, just a little, though that might also have been from the effort in not bucking any harder or arching any further than he already had, still not wanting to cause Peter any damage or even any undue discomfort in his wholly blissed-out state.

He relaxed in stages, breathing still slow and heavy as he did so, the pressure of his hand let up first, sweeping heavy fingers through Peter's hair even as his core and thighs relaxed as well, letting himself drop back to the mattress with a groan.
