Spike teaches Buffy about Sex

I think the story was cannon. Spike hadn't told Buffy about his feelings yet and due to Buffy thinking she is insufficient in some way, Spike begins to teach Buffy how to be good in bed. Cannot remember it for the life of me, but I remember it being a great smutty fic

Buffy is devastated when Liam marries the woman he was cheating on her with - a woman with certain talents in the bedroom. Enter William. He knows exactly what her ex craves, and he's willing to teach Buffy the skills she lacks. But will it help her to win back her ex? Does she even want Liam back?

William has spent his adult life satisfying Drusilla's every whim and desire, but her latest whim involves getting married - and not to him. Alone now, he somehow finds himself Buffy's tutor. Although he enjoys their lessons, what he really wants is her. Will he be able to let her go when the time comes?

Nimbus by Alia has Buffy propositioning Spike pay him to teach her how to give a blowjob after her and Riley have an aborted attempt at intimacy because Riley makes her feel dirty/rejected for wanting oral sex. I am not aware of it online but can send you a copy to check if it is the right one if you pm me your email address.

Buffy also asks for help/teaching in Before I take that walk by pfeifferpack
Spike sobers up after Lovers Walk and wonders why he wants to go back to a cheating Dru anyway. Buffy, meanwhile, tries to get a handle on a future that won't include Angel. Can two broken hearts find an island of comfort in each other's arms and then just walk away?

There's also another all-human au where they are in high school and Buffy's timid about going all the way with boyfriend Angel who dumps her for being frigid. She asks her best friend Spike (who never seems to stay in relationships too long... wonder why?) to teach her about sex.
