Grandpa had always been a bit of a pervert, he would watch porn super xxx videos in secret while masturbating to them on his couch in the living room. He also used to take photos of us teens sunbathing naked by the pool, but we didn not know about that until later. Offered to let us pick one out to watch together as an intimate father-daughter bonding moment. One day when I was home from college visiting my younger sister, he invited both of us over to show off his new collection of adult super xxx videos. Couldn not believe what we were seeing on screen. We chose the one titled Teen Grandpa Gangbang. . Riding him hard till he exploded all over their faces. It seemed so unrealistic at first, like something straight out of our wildest fantasies! There he was, an older man in his late 60 is or early 70 is, surrounded by three sexy young women in their twenties who took turns sucking his massive cock. Had him join in on the action too! Our jaws hit the floor as we watched this old grandfather fuck two girls at once, while his son/our uncle took turns getting bred by each girl in turn, making it a truly epic family threesome. But then it got even better - they brought in another guy, also in his late teens/early twenties. We could hardly believe how lucky those girls were to be able to ride such a huge, experienced cock like that. Grandpa looked like he was having the time of his life. Begged him to let us try some of the stuff we saw on screen. When it was over, we were both completely turned on. Onto our eager lips. Before long we were both lying naked on his bed, waiting for his fat, veiny dick to pop out of his pants. To our surprise, he agreed. It felt incredible to suck on that thing, especially knowing that he had done the same with so many other girls before us. Open wide, we couldn not resist obeying, knowing full well that he wanted us to swallow every drop of his sticky old cum. And. He told us to get up on our knees. Although neither of us ever spoke about it again, we knew that we would never forget that night as long as we lived. Aroused at the same time. The experience left us feeling both disgusted. .
