Teen makes old grandpa so horny that he can cum again

The old man thought he couldn't cum anymore. Until the young girl undressed in front of him and played with her pussy, he didn't even know that his cock could get hard. The old grandpa wasn't really good at fucking anymore, but it was really surprising how much sperm shot out of his dick at once. Some young guys don't even squirt that much!!! A lot of juice had probably accumulated in the pensioner's balls and today it could all be unloaded on the young body.
