Mom in need of a nude model

My mom went back to collage and is taking a photography class and today she asked me to help. she has a big project due but her model canceled on her at the last minute and she needed me to model for her...... nude! I said i would help and we got the shoot started, after a little while she had me get naked. when i hesitated she asked if there was anything she could do to make me more comfortable, i said she could get naked too and she agreed! in between each set of pictures mom took she would text her professor and asked what other pics she needed for her assignment. each time he would have me and then us doing something a little more wild until finally my raging hard dick was in my moms mouth!
