>laser eyes?
Well if you assume they can control output to make it safe for anyone or their partner is superhuman/has regeneration, then it could be used for BDSM or ryona/guro assuming the partner is a hardcore masochist. There's some magic girl fiction that takes that direction (like they can be brutal tortured because body heals when they untransformed).
>frost breath
There is temperature play, honestly dont know if people would enjoy it, but like switching between hot/cold on sensitive areas (Actually could be paired with above, freeze, then rapidly melt it with the laser). Or if it's supernaturally being partially frozen without affecting health, could be used for bondage, binding feet/hands to floor or preventing movement of most of body like petrification fetish.
>mind reading
Simple thing would be knowing exactly how to please their partner. I'm quite partial to the idea of a yandere cuckquean, so with mind reading they could figure out who their love interest likes and how to get them into harem. Aside from that, maybe expand the power to like sensory/emotion sharing as well, so sex where both sides can feel what the other does.

Anyways, there's some quick ideas. Hope it helps.
