Your visits to your stepsister have always been a pleasure. She greeted you with a warm hug and a kiss on the cheek. But soon one visit changed everything.... it was to be your sexual epiphany! On this particular time, you entered your sister's apartment and called out to her as usual. Hearing no response, you went in search of her. When you opened the door to your sister's room, you saw her in her frilly and sexy lingerie. She didn't seem embarrassed, as if there was nothing surprising or strange about it. So you walked fully into the room. Receiving the usual hug and kiss, your cock went from flaccid to hard in about 3 seconds. You hurriedly covered this misunderstanding with your hand, hoping that the arousal would subside soon. But your sister decided to do something different. She started twisting and turning, showing you her sexy new lingerie, asking you to rate the look. The lingerie really was beautiful....or was it the blonde's semi-nudity that attracted you so much. You couldn't exactly answer the question. You couldn't do much at all. You were already thinking with the iron erection of your dick in your pants. And, by the way, you seemed to stop watching it and soon your sister discovered your noticeable bulge in your pants. Her eyes went to the front of your pants. There was an awkward silence in the room. Your sister moves closer and wraps her fingers around the bulge in your pants. “Let me help you,” she whispers in a low voice, pulls you onto the bed and kneels down.....This is a day you will never forget
