Lyra Law, a bubbly teacher, is busy grading her students' art assignments when she uncovers a submission containing naked pictures of one of her students, Whitney Wright, submitted by another student, Elena Koshka! As she stares at the nude pictures, Lyra tries her best to judge it as art. It has good contrast, good use of space... No, no matter how hard she looks at it, it's not art -- just a gratuitous naked photo! She can't grade THAT, she's a teacher! It's beautiful, though, and Lyra loves the curves, the eyes, the most beautiful pair of tits she's ever seen...When she calls Elena to tell her that she can't accept the pictures, Whitney picks up the phone instead. Little does Lyra know, Elena is happily naked, waiting for HER turn to get pictures taken! Lyra learns that they had a deal to exchange pictures, so Elena is a LITTLE tied up right now...Lyra gushes about how sexy the pictures are and what a bummer it is that she can't grade them because her bosses won't allow it. The pictures need to be more artsy and less... nude. What if she comes over there and helps them take pictures before they continue any further with the project?Lyra arrives at the address and finds Elena literally tied up, with a bit of red ribbon loose around her wrists. Lyra is surprised and tries her best to remain professional and hands-off as she teaches the girls how to do tasteful nudes. Despite her best efforts, she somehow ends up with her hands cupping Elena's breasts in an attempt to cover the nipples for the next set of photos...When Whitney announces that she's satisfied with the pictures and wants Lyra to take pictures of both she and Elena naked together, Lyra's too hot to turn the offer down. So hot, in fact, that when they later ask her to join them, she's unable to resist. Soon the camera's forgotten as Lyra loses herself, pinned between the two sexy, younger women. They all take turns licking each other's pussies and getting their fingers wet. The last thing on Lyra's mind now is how this will be graded!
