Finally got my sister in law to give me rimjobs, should she be taking some kind of medication to prevent getting an infection?

Question

Update:

Wife's twin sister 

Update 2:

She rarely sticks her tongue inside, mostly just licks on the  outside 

Answer 1

Bet your brother is happy that she takes care of you.

Answer 2

I believe this to the same extent I believe all of the sexual fantasies you've posted.  You are a sad and lonely person.

No normal person posts the same type of questions for five years:  "My sil has me licking her butt all the time, basically uses me as her slave, how do i get back to her performing oral on me?"

Answer 3

You both need your heads examined , you moron.
