A full week

While time isn't the best thing to keep track of in a sex dungeon, you are able to figure out that the two of you have been fucking for a week. Arlo seemingly give you a pill like clockwork, so that's why you assume you've been trapped for a week. For what you thought were the first three days, you were taken in the breeding stand. He would let you loose whenever he was done, but whenever he came back down you would have to go straight back in. Then he changed up his methods, moving you to the bed. Sometimes he would tie you down, giving you no wiggle room as he fucked you into the mattress. Sometimes, when you could tell he was a bit tired and didn't want to go through the hassle, he simply pushed you on your side and would fuck you like that.

You can tell he doesn't want to let you have any semblance of control. He wants you to know that, for however long he lives, you're going to be his breeding bitch. And you quickly accept that. You are in the middle of nowhere and no one knows you're here. Better to make it easier for yourself instead of fighting back.

After the week is up, he takes you upstairs with him. You're confined to the first floor, but you're just glad that you're no longer trapped in the basement. You assume that he doesn't just want you for breeding, since he explains to you that you're responsible for taking care of the floor you're on. He wants a wife without the romantic feelings involved. You can understand why.

He still takes you down to the sex dungeon for breeding, testing you out in different positions and with different toys, but he never removes the chastity belt on your cock and always cums deep inside your body. He wants you to have his baby and he wants it bad.
