Stepsister's Duty to Give Stepbrother Some Booty

Anna De Ville has a fantastic weekend planned with her boyfriend. They have great sex, but have never tried anal. She plans to change that as part of his birthday celebration. . When she goes to the kitchen to have some breakfast, she finds her stepbrother already there. She also finds a cake her stepmom baked. It looks too good and Anna takes it out for a taste. She kneels on a barstool and her short dress slides up too until stepbrother gets a look at the anal plug she is using to get ready for her big date. Embarrassed she begs him not to tell their parents. He confesses that he has never tried anal sex. Since stepsister has done it many times, just not with her current boyfriend, she offers to show him how it's done. She tells him she will need to suck his cock a bit first to get it hard. To her shock and delight, Anna finds that stepbrother's cock is already rock hard and quite large. She sucks it anyway to get it good and wet.
