Well, look...

The blindfolds would bother me. Until you consider the girls knew they were being blindfolded and knew what they were licking. Beyond that, it's all a matter of consent, just as with anything else.

Having blindfolded girls suck things off bananas to get yourself off is not something a girl lover would do. This man had no respect for these girls and treated them as nothing more than sex objects.

If the girls thought it was funny being blindfolded and loved the tasty treats, then let the man enjoy the show. OTOH, if he forced the girls to blindly lick bananas then he's a bitch! Llort is right, there's shades of grey to consider. I wasn't there, I have no right to judge the man based on what I don't know.

The next step would be to put sweet stuff all over his dick and have the girls suck it off while still blindfolded.

O_O

Either you've got a really weird dick or you need to call shenanigans on yourself.
