We present a new study of D semileptonic decays on the lattice which employs the Highly Improved Staggered Quark (HISQ) action for both the charm and the light valence quarks. We work with MILC unquenched $N f = 2 + 1$ lattices and determine the scalar form factor $f 0(q^2)$ for $D ightarrow K, l u$ semileptonic decays. The form factor is obtained
