Staging is super, but the script could have been finished in a more interesting way, for example, either the awakened girlfriend would have thrown the friends out into the street, or even joined them and looking at her friend obliquely would have screwed her boyfriend much cooler than a mulatto!
Any sister should help her brother get unloaded. What does it cost her to give a blow job or let her in the pussy? It's not like she's gonna get wiped in a couple of times. But she'll get his respect and an extra workout in return. Plus she gets to taste his condensed milk for free. )))
