Demon driven oral s.ex

I read a fic that was early season, Buffy and Spike were together or getting to know each other, she is young/inexperienced in it and after a fight or some such prompt Spike's demon kind of takes over and forces Buffy to kneel and starts punishing oral s.ex with her outside a crypt but he then comes back to himself and realises what he is doing and is hugely apologetic but she is just worried that he wasn't liking it or she was doing it wrong. Does this ring any bells to anyone?

Could it be Beloved by Blood, by Ameeya?

There is a story simular to what you discribe, but i myself cannot remember the name of it. I will discribe the story i am talking about and perhaps someone else will know the name of it. The story is a bit long, it takes place season two. Both Spike and Buffy still hate each other but they start having dreams where Spike and Buffy are in a hotel room. Only these dreams are dreams and they are actually in each others head in this hotel room. Anyways the first night Spike is detemined to prove that is just a dream, and because its just a dream he fucks her face. Buffy protests at first but at the same time enjoys it. They realise that these meetings aren't just dreams and is part of a prophecy...

pretty sure the one the person above me is talking about is dreamscape by holly
like they pointed out though it's not near the crypt but in a motel room

The first request I'm sorry I cannot remember the name and I only re-read a couple weeks ago too.
This ' Demon driven oral s.ex ' thing happens against the crypt after Faith comes on to Spike and he snaps and says all these things about how Faith is pathetic and thinks she deserves everything Buffy has then something along the lines of but Buffy is better than her. Then he beats her up. Buffy sees this from a distance.

It must be a claim fic cause I remember that Spike felt sick when Faith touched him. I'm pretty sure too that Buffy felt sick every time Giles or Xander touched her.

Hi again,
It is; Beloved in Blood by Ameeya
as the first reply said (and the part you're talking about happens in the chapter of this link-chapter 33)
