She sucks your cock

"Time to show you how an experienced woman sucks a cock. Let's see if you can last more than 5 minutes."

Even though you're letting Diane take the lead now, in the back of your mind you can't help but think 'who does this bitch think she is'.

She starts slow, licking around the hilt of your shaft with her surprisingly long tongue. Slowly, she works her way upwards until she gets to the tip. Here she spends some time playfully licking the sensitive part around the cusp of the head of your cock before licking around the engorged glans of your dick.

Once she feels she's spent enough time teasing you, she inserts just the tip into your mouth. With just the tip inside, she playfully flicks her tongue around, providing immense pleasure. You feel like she could live up to her own hype and make you burst soon, but you know this is just the beginning.

As soon as she's had her fun toying with you in this way, she slowly slides your cock deeper into her mouth until you feel it hit the back of her throat. Once you reach this point you feel a brief moment as she pauses, suppressing her gag reflex before sliding further down. To your shock and amazement, she simply continues going down and down onto your cock, sliding it further and further down her throat until she amazingly manages to touch her lips to your pubes. Seeing a feat like this is a testament to her age and experience, demonstrating that promiscuity clearly runs in the family.

Fully sheathing your cock in her throat, she pauses there a moment until she can no longer hold back her gag reflex, or her breath, and comes back up for air. Quickly sliding your whole cock out of her throat like this, you're reminded how impressive it is she was able to get the whole thing down in one go right from the start.
