The Dimensions Where He Likes Dick

You're Mary, 22, and fine as hell, but that doesn't matter. This story is a montage of your adventures into the gay transgressions of your boyfriend in alternate timelines (past and future). He's Sam, and you are not ready for the shit he has gotten into.

You found a device that lets you flip freely through infinite timelines, subset to times Sam felt a desire for cock. Specifically, the device mentions these are first time experiences from other dimensions. It doesn't matter where you found it, no more setup necessary; start flippin' those channels, yo.

Note: I'm not sure why it says the category is BDSM. That's not the focus of this story, sorry.
