You get home from work to see your girlfriend sitting on the couch reading a book. She is still in her work clothes and is looking really hot. You especially notice her long legs and how great they look in the sheer black pantyhose she is wearing. She looks up at you and smiles. After greeting you she begins to strip down in front of you. What a nice treat after work. "I love the way you are looking at me right now, it makes me feel so sexy" she says with a sexy smile. She goes to take off her pantyhose but you stop her. Her ass looks so good in those pantyhose you don't want her to take them off. That's when she has an idea. She wants you to jerk off to her amazing body while she teases you with her ass and tells you exactly how to jerk yourself off. You two have never done anything quite like this before and you are excited by the idea and quickly agree. You get down on the floor so she can put her ass right in your face. She instructs you to start pumping your already hard cock and you do so. It feels so amazing, jerking off to your girlfriend's hot ass, having her tell you exactly how she wants you to stroke your throbbing dick. She ups the ante of her little game by telling you that you are not allowed to touch her ass, you must fight the temptation, because if you touch it, you will not be allowed to cum. And you do want to cum, don't you? Because when you do, she wants you to cover her ass with your cum. Your girlfriend continues to tease you. She slowly moves her ass in front of your face, she rubs it and squeezes it. Your dick is already to explode, it's pulsating in your hand and the pleasure is already building to a crescendo, but she won't let you cum until she is ready for you to. She makes you back up for a little bit, so that you can really see her entire figure. Her body is driving you insane. You want to speed up your stroking, your dick is begging you to, but you have to stroke at the speed she tells you to. Finally, when she has had enough fun, she tells you to come really close to her. She begins to countdown from twenty and when she gets to zero you are then allowed to cum. All your pent up cum explodes from you, soaking through the fabric of the panythose and drenching her amazing ass in cum.
