The calling mark

Regulus is at the potters and his bother as well as James's parents are not home.He hasn't presented yet and then one day he goes into pre-heat.He gets a calling mark witch is made up by me(idk if other people are Have something similar but I thought of this).And his calling mark just tells him that it is much much more urgent to spent there heat with but James is only person in the house when he gets the calling mark.And if he doesn't get fuck by someone knot he could die....
