Ask for a blowie

Fortune favours the brave as your grandfather always used to tell you. You decide to go ahead and push for the maximum you can get out of her.

"Hmm... I guess the quickest way is if you know... take me in your mouth?"

She scrunches up her nose. "It's too risky. Someone might come." (Yeah, hopefully yourself! You think).

"I'll keep a lookout and beside your head will be down, you'll be hidden from view."

She gives one of her **** sighs. "3 minutes only, and no cumming in my mouth."

"Promise!" You say already pulling her down towards your twitching cock.

"I can't believe we doing this," she says before giving it a little exploratory lick. She then purses her lips over just the tip, going back and forth a couple of times.
