Playing With Precum

Dr Callie is conducting research on precum and has called Max in to demonstrate the enormous amounts of precum he produces when fully aroused. She asks him to show her his juices but he explains he will have to jerk off in front of her and also look at some sexy images. Callie hasnt got any porn to showm him so she offers to strip off herself. As soon as she takes off her skirt and shirt, Maxs dick starts leaking, streams of precum flowing from his penis. Callie sit in her lingerie and plays with his precum with her hands, stroking his cock while she does so and he soon has a big ejaculation for her!
