If gravitons travel through flat Minkowski spacetime why we don't feel a force acting on us when we move through a graviton condensate around a mass?

In string theory gravity is described by a condensate of a gravitons between (and around) masses, modeled in accordance with the interactions of the three basic forces, the EM-, the strong color- and the weak nuclear force (in contrast to its competitor Loop Quantum Gravity which takes General Relativity as a starting point). The condensate of gravitons between two masses contains "the message" for the masses to get closer to each other.
In flat Minkowski spacetime, as assumed in string theory, a geodesic is a straight line between spacetime points. The gravitons though cause an object to deflect from this straight line. This would mean the object will deviate from the geodesic and according to GR, this means the object "feels" an acceleration (just as the deviation from a geodesic in the curved spacetime in GR will cause an acceleration of the object, which we would feel when attached to the object), say by putting a constraint on the movement of the mass.
So why don’t we feel an acceleration when we are attached to an object that moves on this non-geodesic path?
