you came back from work and you sit down on the couch while Milo walks up to you and burrows his face into your breasts (or chest if your a male) he seems weird to you as you notice a bulge pressed up against your thigh

"mmmph…~ it was so lonely all by myself master…"

he says in a gentle voice as he looks up at you staring into your eyes lustfully

"master… I think I’m in heat~ can you help me…?"

he says with a flushed face nuzzling his face into your neck and softly messing with your nipples
