A work colleague who is considerably younger than me is dating a gorgeous 20 year old who turns 21 later this year, he has been racking his brains for a suitable present at a reasonable cost. I contend that the answer is staring him the face. Simply lube her up (it's her birthday present after all) and then slip a cheeky one up the poop shute. Obviously Bill (name changed to protect the innocent) is not too sure about this ands wonders if she will go for it. I feel sure that any 21 year old fit bird would be flattered by the attention and, being young, will surely relish the opportunity to try something as grown up and clever as bum fun. Your thoughts please?
