"It's fine to suck it, isn't it?" A super-time-saving blowjob that makes her black gal sister suck in her mouth in 5 minutes

It was my first time staying at her house. Apparently she lives with her older sister, but apparently she isn't there today. When I took this opportunity to arrive at her house, there was a naked gal right in front of me... this gal was her older sister. Then he stared at me with sexy eyes. The frustrated gal sister after breaking up with her boyfriend says, "It's fine enough to suck it, right?" and gives a blow job in the unlikely event that her girlfriend is around! This feels so good that I'm dying!
