Part 1: Even after becoming an adult, Spike had no problem still living with Twilight. Even if she's a busty mare, she's also like a sister to him. However, Starlight is just as busty and doesn't have the baggage of a familiar relationship. Nah, he can't possibly make a move. Wait, she's taking away his personal shower time too?! Fine, he'll just steal the shower from her... and rip off her bath towel... and doing everything else.

Part 2: Twilight has no problem with her brother getting laid. However, when it involves a busty mare they both have to live with... That might be going too far. Especially when Starlight starts flirting with the alicorn too.

Originally planned to have sequels. But I decided just to combine both parts into a single story. Part 3 will go up on the 29th. Part 4(Finale) will go up on May 3rd.
