Artist twins take advantage of student

Your art teacher invites you over to admire & enjoy some of her and her twin stepsisters art. You are after all her favorite student, and you're definitely going to get that college scholarship. Your art teacher Kelly invites you over to view and discuss art, mostly her favorite... the naked male and his beautiful penis just like you had discussed in class this morning going over the greek statues and the sizes and shapes of their penis hypothesizing what their penis size would be if made today in this modern age. Your teacher encourages you to take a shower after a long walk out in the garden, she takes your clothes and has a somewhat agenda... she'd like to you pose nude for her and her twin stepsister. She's like to make you her masterpiece. Though her twin stepsister is rather out there, entering the room after her shower completely nude only wearing a slight covering on her arms, though she is your teachers twin her personality is extremely different....
