2T4U/Jack/Morning/Fiona's/Suggest that Fiona should give you a blowjob
"Oh yeah?" you reply, putting a hand on Fiona's breast and nudging her off of you. Once she's on her feet, you unzip your pants and fish your rock-hard cock out into fresh air. Fully erect, throbbing and glistening wet with precum; it's truly a sight to behold, and Fiona clearly respects that fact. Her jaw drops with a grin, and the icy blue eyes grow wide with enthusiasm.
"How about you get down and suck it?"
Fiona hardly needs any more encouragement. She quickly gets on her knees and buries her elbows in your lap; grasping your monster length with both hands, barely able to wrap her fingers all the way around it. She squeezes it in her grip a little, clearly unable to figure out where to even begin. Then, after a while, she carefully sticks her tongue out to touch your pee hole; softly licking against your slit while the hands pump your shaft. She puckers her lips and rub them against your head; smearing precum all over them and sending quick, ticklish jolts all through your body.
The old woman clearly knows how to worship cock; but so far she's just being a tease, and it's starting to make you a bit antsy.
What do you do?
