Hitomi smiled softly to Trina, gently kissing her lips before moving her little niece off her lap, and pulling her self up into sitting on the edge of the bath with her legs in the water, her cock out and erect for Trina. "mm..Well..first I'll teach you how to give me oral when I'm like this.." Hitomi said with a smile to Trina, softly running a hand through the girl's wet, golden locks. "Now...it's going to be strange at first..but you'll get used to it as we go along." She smiled softly and reached down, taking Trina's hand, and placing it on her large penis. "First..stroke up and down the length, like this." Hitomi said, softly moving Trina's hand up and down her hard length, which caused Hitomi to let out a small squeak of a moan, as she was still sensitive from last night. "M-Mm...W-when you feel comfortable, Trina...lick the length with your tongue, and then take it into your mouth and suck softly...Ok?" Hitomi smiled to her niece...she was teaching her such Naughty things this morning...Hitomi hoped that the other prefects would be too busy with breakfast to barge in..
