It's the morning of your birthday and you have decided to consult Dr. Hans Jerkoff by using a sock to enhance the feeling. But, as you were rubbing one out, your insanely hot blonde stepsister Cayla Lyons entered the room bringing some cake and balloons with the intentions of congratulating you. Her sexy lingerie was more than alluring for you at that moment as you could see her perky boobs peaking shyly out of her bra. Oh, and she also wanted you to get up at this really awkward moment for you, which is why she pulled the sheets from your body only to be greeted with the sight of your erect and huge boner wrapped in a sock. A nervous chuckle was her initial reaction, but then, as she admired your penis’s length and firmness, a certain warmth started spreading in her nether regions. This, naturally, prompted her to grab a hold of your massive dick and put it in her mouth for a sloppy, yet incredibly good cocksucking session. Then, she slowly slid your large member deep inside of her moist and wanting beaver and went on to ride it both in the cowgirl and in the reverse cowgirl positions. When you were about to explode, your cute stepsis wrapped her lusty lips around your cock once again and let it explode inside and around her mouth. Well, if that is not the best birthday present ever, then nothing is!
