Spike knew what he came to visit for. He went over his options ever since Rarity left for Manehatten a week ago. Twilight was like his sister; Pinkie was far too energetic for him to handle; Applejack was Rarity's rival, so admiring her would be fairly weird for him to accomplish; Rainbow Dash would get bored of him and try to ditch him somewhere.

But Fluttershy, whose physique was more of a motherly figure than any of the others possessed. Fluttershy surely had the goods, even better than Rarity, for him to admire. But temptation settles in and Spike is not sure that he'll come home today and know that all he did was "admire" Fluttershy's body. He'd have done a lot more by then.

These two virgins will certainly enjoy giving up the V-cards which they held for so long.
