an ambiguous verb

In another thread an Irony impostor wrote:

"I am not very sparing with my cum when Franco deep throats me."

Is this correct or should it be the other way around, i.e. the person whose cum is being slurped up should be the one doing the deep throating, right? Or can "to deep throat someone" refer to both ends of the action? If so, are there any other verbs like this, i.e. a transitive verb where the receiver and the doer are doing the same action (both of them are deep throating, instead of one deep throating and the other being deep throated)?

Dear Franco

'Cum' is short for 'come'.

In the sense of 'are you ready' or 'have you come yet'.

Have you heard 'Relax don't do it'?

by Frankie goes to Hollywood.

Death to Robin Michael! I hope he chokes to death with his own cum!

<Is this correct or should it be the other way around>

The receiving party deep-throats, in the same way that the receiving party fellates.

Therefore the Irony impostor was correct.
