Old man wanking in park

One of the things I LOVE best is watching older men wank in public with people maybe seeing. I've heard there's usually flashers at the botanic garden in the city so I went to see. There was a man sitting on a bench rubbing himself as if he was going to get his dick out so I casually walked over and sat on the bench to. We spoke a bit just about the weather and I was talking he undid his zip and and started to squeeze and rub his bulge. I just watched and he saw that I didn't go away so he kept doing it. He asked if it was ok if he took his cock out and I said yes. We just kept chatting and he was really nice. While he wanked I asked him things like if he likes young girls and he said he likes when they touch him. I got closer so I could see better. There were people around and it really turned me on. A couple of ladies even walked up pretty close. He started breathing heavier and telling me I have nice tits. My nipples were hard so I slid up against him so his arm was against my right tit. He said you're going to make grandad cum. I couldn't stop staring down at his massive cock. I said really quietly that I wish I could give it a big suck and his cock exploded. His cum was all over the ground and a lady looked at it when she walked past a couple of seconds later. The man got my phone number so he can text me next time he's going. He works in a office across the road so its really handy.
