Дрочить його для науки (з Еббі Кросс і Лолою Фокс)

Working hard on a science experiment, your step sisters find that they need a sperm sample from you. They ask if you will jack off into a petri dish so that they can examine your sperm under the microscope. They are highly motivated to assist you in obtaining that sample as they drop their crisp white lab coats onto the floor. Immediately you follow their instructions. You would hate to be the reason that their science project went awry, right? You are doing such a good job jacking off that Abby and Lola take off their bras. Their young bodies are so very firm, but their jiggly asses bounce perfectly. They look like sexy geeks wearing their glasses. The girls are hopeful that you can produce a very large load. Remember, this is for the advancement of science! Abby and Lola are certain to share all the up-close views of their bodies with you as they bounce and jiggle. It is now time to give them your sample and the girls urge you to pump right into their petri dish.
