When your father passed away, you knew your mother would be sending for you at the boarding school where you started last year. You knew she wouldn't want you to go back, either, now that she was all alone. But you never expected to return to a house so changed from the one you had left. It was evident first in the way your mother was acting. Sure, she was upset about your father's passing, but not like you expected. And she seemed to be very flirty with several of the men, none of whom you recognized, that stopped by to pay their respects. In some attempt at grieving in a way that you found more appropriate, you went to look through your father's belongings, only to find a stash of thumb drives hiding in the closet. Popping them into your dad's laptop, you sat on his bed and watched as your mother appeared on the screen. Then, another man. Your father's voice behind the camera as...oh my god. You shouldn't have watched, but you did - you watched your mother take cock after cock, each one enormous and stretching her shaved pussy as your father encouraged them, stroked them, helped guide them into your mother. Your father was a cuckold! Your cock rigid, you stroked to the videos until you had a shameful orgasm there on your parents bed. The very same bed from the videos. When you were done, you put everything back where you found it...but all of that was for nothing, when your mother sat you down the next day to "talk." About what she saw you watching in her bedroom. You assume that there's a lecture on respecting privacy coming, but instead she tells you that you have a role to play in all this, now that your father is gone. What? You can't believe what you're hearing but your mother goes on to admit that the fiber supplement in your OJ was actually something to put you out, so that she and the nieighbor boy, a former classmate of yours, can tie you up. And train you. Break you. Now that dad's gone, she needs a new cuck to service all her strong, thick-cocked bulls. And you're going to be that boy! You try to fight the effects of whatever it was she slipped you, but its no use. You fade into oblivion, only awakening when you hear your mother's teasing, lilting voice. She stands before you, naked except for these sexy black thigh highs. She is instructing someone behind you, but you can't turn. You are tied to the bed, completely immobile as she instructs the boy behind you to spread your ass and place his cock against your hole. You try to resist but its no use. You're not going anywhere, your mother teases, as you feel the impossibly large cock of your mother's new bull pres against your anus. Your gorgeous, sexy mother places her pussy right up against your face as she tells the bull to push in, to pop your anal cherry with his huge cock. She taunts you as he begins to pump your virgin asshole, pressing deeper, fucking you balls deep while you watch your mother finger fuck her delicious, dripping wet cunny. You want to please her, you realize, even as what is happening to you is shameful, painful, shocking. You find yourself losing the will to fight as the massive dick in your ass bottoms out, and cums deep inside your bowels, filling you with sticky seed. Your mother has begged him to do so and now, seeing your face as you register the warmth spreading inside your ass, she cums hard and you watch her perfect pussy spasm in delight at her own son, broken by her bull.
