Stepsister's first time with big cock

Two young girls, who are not related, are about to have their first experience with a big cock. They are both excited and nervous at the same time. The one with the bigger boobs is the one who is more confident, while the other is a little shy. The guy who is about to fuck them is also a little nervous, but he is ready to give them what they want. The girls are both on their knees, and the guy is about to enter them. The girl with the bigger tits is the one taking the brunt of the action, and she is moaning and groaning with pleasure. Her sister is watching and can't help but feel a little jealous. The guy is pounding her hard, and she can't help herself from cumming. The guy then turns around and gives her sister a load as well. The girl is still moaning and can't believe what she just experienced. The guy tells her that he will be back to fuck her again, and she agrees. This is the first time for both girls, and they are not disappointed. The guy takes them to the brink of orgasm, and they both come hard. The guy leaves satisfied, and the girls are left with a memory that will last them a lifetime.
