Emiya(the dog)is kinda self-abandoning kind of person so he sometimes do stuff like this. Horse Boss don't want him to be so but is currently taken over by lust.
I didn't expect them to be like this....bold especially Emya. I like the way he holds the boss's arm and the way he's sitting. He seems to be really aware of what he's doing judging by the expressions on both of them. 😤 And in any case, I personally think that the place they have chosen is among the most erotic, especially when you understand that two people like each other so much. 🔥Happy Valentine's Day!!!❤️
