plenty of good hentai with presence disregard tag to inspire the guy of an out.
she'll likely fold on the first couple of touches tho, so he should chose his strategy carefully.
if he likes her physically but still wants to be rid of her attitude, go for maximum points and start strong, like directly a kiss or fingerbang.
if he actually likes her or the situation/attention, start slower and probe her limits without crossing them.
if instead he likes some random observer girl, don't risk scoring points with this one and slap that thigh with the hardest BEGONE THOT he can muster.
