When the auxiliary verb せる (or させる) ‘to make/let do’ is combined with the auxiliary verb られる ‘to be the receiver of’, it creates the causative-passive form of verbs in Japanese. These sentences will be from the perspective of the person who has ‘been made to do’ something, and are very often negative (against the will of the speaker).
First, verbs must be conjugated in the same way that they would be with せる, or させる. After that simply remove the る, and then add られる. This will create the verb form させられる (linked with る-Verbs), or せられる (linked with う-Verbs).

• おばあちゃんの家（いえ）に行（い）くとお腹（なか）がいっぱいでもいっぱい食（た）べさせられる。

• 先輩（せんぱい）に色（いろ）んなお酒（さけ）を飲（の）ませられたから頭（あたま）が痛（いた）い。

• 友達（ともだち）に冷（つめ）たい水（みず）を浴（あ）びせられるのが嫌（きら）いだ。
  I don’t like it when my friend douses me with cold water.

As with the causative form, する and 来（く）る have special conjugation rules. する will be replaced completely be させられる, while 来（く）る will become 来（こ）させられる.
