Max knows his big brother. knows just where to touch, to kiss, where to lightly bit and where to dig his teeth into. He knows that if he were to suck on that spot right above his collar bone the older boy hips would jerk and his eyes would fall close . he Loved that every time he licked Justins hole, big brother would beg him to thrust deeper, pulling his cheeks apart and spread his legs, exposing himself shamelessly to his young brother. Max would oblige, as he always does, stiffing his tongue breaking that outer ring of the muscle, loving every broken moan that filled the room. But he knows Justin wants the pain, wants max to dig his nails into his chest, bit him till he bleeds, spank him till his ass is bright red then fuck him dry till he cant think straight, mark him as his and only his. Max does every thing and more ,because he can only know exactly when to whisper in his ear, that he likes alittle teeth when getting his cock sucked, loves it when his slit is tongued and his balls are fondled roughly. No one knows Justin like Max does, and no one ever will.
