More ways to rile up that nerd 💜:
'Accidentally' drop a pen under the desk, go to fetch it and juuust so happen to find it while your head is between his legs.
Getting a book from a high shelf and letting your robe ride up higher and higher as you go to reach for it, right in his eye-line.
Leave explicit messages and pictures in the middle of the books he's reading. Watch him try and keep his composure, try to hide his blush. Walk up behind him and oh-so-innocently ask him what he's reading; Is it any good? Would he recommend it?
Sitting in his lap while he's trying to read. If he tries to persist, start grinding.
Insist that you need his help reading a passage from a book and, when he starts reading the words out loud, start tracing shapes into his thigh. See how long he can last reading while trying not to moan or whimper too loudly.
Sit next to him and just don't do anything. No touching or teasing. Let him feel on edge. Keep him guessing.
Finally: give him a quick kiss on the cheek while hes focused. Sure, its not as perverted as the other suggestions but it'll probably still get him worked up <3
YOU'RE SO RIGHT. Quick kiss on the cheek would 100% make him cum if you'd already been teasing him all day <3 all of these are so good i am writing them down i am writing them down frantically
you embarrassed him though :( wonder if you ask nicely if he'll move that wing
