Anal [M]asturbation in hospital (22 years old)

So, I have been in this hospital for a week now and I got super horny. I am sleeping in the same room with two old guys so masturbating is definitely not an option. I go to sleep until a huge urge to masturbate comes. I can’t do that because we were having drugs injected in few minutes (They wake us up). So I decided not to jack off but insted stick a finger up my butt. (I am kind of experienced in butt stuff).

(I have a self lubricating ass so I have no problems with lube because I just don’t need it) So I have my finger fiddling around inside while others are snoring. It felt super good. I felt like if I touched my cock, i’d immediatelly cum, but as I said, I couldn’t jack off because nurse can come any second. So 30 minutes pass by, I am playing inside and finally nurses come to inject the drugs. After 20 minutes of waiting for the dudes to fall asleep, I can finally jack off, but I decided not to and instead stuck a few more fingers inside. I was almost fisting myself but then, one of the dudes went to the toilet. I quickly stopped and pulled my hand out.
