If you like extreme sex and domination, tragalexe accepts you to hit him and in a general way degrade physically and psychologically.
Physical degradation
You can hit him, he swallows your spit, your piss, your snot and lick you under the armpits.
If you fucked him so hard that it makes his mouth or your ass bleeding it does not matter.
Just ask or force him.
Psychological degradation
You can tell him what you think of him.
All the above is only to give ideas, if there are more things you want to do, just do it while the mutual anonymity remains respected.
