imagine only being allowed to cum from your ass. it's tough at first. anal is painful and humiliating. but every time he fucks your pussy, you quickly dissolve into a wet, whimpering mess, as all of your dwindling brain-power is used on trying to keep yourself from cumming. eventually, the denial becomes too difficult, and with time you learn to enjoy having your ass fucked. the first anal orgasm you have rockets through you like a punch in the gut. it's the first orgasm you've had in weeks despite being fucked every night, and once it starts, you can't stop. every night, he asks you if you want him to fuck your pussy or your ass. every night, you are forced to make the choice between denial and humiliation. and as the weeks drag on, your wet, neglected pussy becomes nothing more than a lube dispenser as you beg over and over again for him to fuck your ass
