CFNM Exposed Dianne, Emilee and Mark Picture

Dianne and Emilee are studying the male anatomy for school and they're a little bit confused with all of the actual terminology and such. So they decide to call over a male doctor friend to help them and he agrees. So awhile later the friend drops by and he brings some of his own teaching guides but it's not helping the girls. So they talk him into dropping his own pants so that they can inspect his anatomy. So the girls get on their knees and start stroking off his cock. Then he bends over and the girls stick a gloved finger up his asshole. Both of the girls are fully clothed as they continue to stroke him and then he cums in their hands.
