Lily doesn’t give Oliver the chance to change his mind. Hiking up her miniskirt and tugging her panties aside, Lily sinks down on that fine dick while Sera watches hungrily. She rides in cowgirl so Oliver can see that it's his stepsister fucking him, then tags out so Sera can give him a reverse cowgirl stiffie ride. Falling onto her back, Sera spre her thighs to welcome Oliver back inside to bang her as Lily climbs aboard to ride her eager face. Then Lily takes her turn in the middle on her knees with Oliver doing her in doggy and Sera mewling in delight as Lily eats her out. Sera only moves when Oliver pulls out of Lily with just a few seconds warning before he cums. He nuts all over Lily's ass, then watches as Sera licks Lily clean and snowballs Oliver's load with her BFF.
