Trina gasped, pulling back slightly when Hitomi finally came in her throat, blushing softly when her aunt pulled back, giggling as some of the cum squirted out over her lips and chin, licking it up hungrily.  She watched in interest everything that Hitomi did to Rika, and giggled, blushing as she realized she was rubbing softly at her own cock as her aunt spewed in Rika's mouth again.  She smiled.  "You'll have to teach me that one, Aunt Hitomi," she said, pulling her hand away from the cock hesitantly, smiling softly.  "I mean, if you're going to teach me the one that... well, you know," she said, blushing as her hand crept back to her 'cock'.
