Why can't we see such love and passion in hetero porn? It always look like they're performing a task, just pumping till he cums on her face, with no interaction.
I think the reason we guys like lesbians is because it's about the only place left in porn when there is passion (fondling, french kissing, lusty eye contact) as opposedto grunting ass ramming from behind with barely any contact between the two.
