She has Shirou's cum everywhere . . . and she loves it more than anything.

Does this count as bukkake?

And how many h-scenes did she have with Shirou anyhow?

Three I think, which would make them more than Saber(2 from what I gathered) and Rin(only one) had with Shirou
Not counting in Hollow Ataraxia

shirou has sex with her in the fate scenario where saber is running low on mana, with the um, berserker fight ep. 15, and then he takes a bath with her, and does her there as well, although i recall there being one more, i thought rin was caught touching herself, but maybe thats ataraxia, x3

Baby fucking where?

The worms eat the baby
