Shelby was visiting an old people’s home when she overheard a man with dementia complaining that he’d forgotten his age. Shelby said that if she sucked him off, she could tell him his age exactly. The man was puzzled but happily agreed. Due to his advanced age, it took a little while for him to get an erection and it wasn’t as stiff as it would have been 20 years earlier. Nevertheless it was impressive for such an old guy, and he finally released his load. After swallowing the lot and him pulling out, Shelby said “You’re 84, born in 1941”.
The guy is astounded. “That’s fucking amazing!”
Shelby wiped the last drop on jizz from his cock with her finger and spread it on her lips.
“April 23rd” she says, in her usual sultry voice.
“Fuck. God, I don’t believe it. How do you do that? How can you be so sure?” he asks.
Shelby, in a quiet seductive whisper replies
“It’s written on the patient notes, above your bed: Bill Jones, 84, 23rd April 1941, Dementia, Blood Group O⁻, Coffee black 2 sugars, loves sport on TV.”
