You unzip your pants as Sarah falls to her knees and fondles with your cock (not that it isn’t already rock hard). This obviously causes a riot in the library, but you stop it before it gets anywhere near out of hand:
/Nobody cares that I am getting head in public/
Everyone no longer blinking at the sight of a blowjob in a library, you turn your attention to Sarah, who is struggling down there.
“Uh, it’s not really feeling all that great,” you mumble.
“This is...my first...one...” she says between her attempts at sucking and slurping. “I’m...oh I’m sorry I’m trying my best...”
You aren’t that annoyed because you can fix this:
/Sarah has given head dozens of times before and she’s very, very good at it/
Immediately, Sarah’s form improves and now she’s sucking like a total slut. You moan as the pleasure finally washes over you and you-
“Ah!”
Like a true slut, Sarah swallows your load and looks up at you happily.
“Mhmm I’ve sucked plenty of cocks but you tasted so good!” She remarks.
