Harry and Hermione walked into the broom closet to start SNOOOOOOGING like hell, ya know like normal teenagers. And let's just say it got heated pretty fast, 'cause in just a few moments 90% of their clothes were on the floor. Their hands started to wander all over the others body, Hermione's hands could feel the soft muscles underneath his skin (most likely from all the quidditch) . Harry in turn let his hands wander all over her curves, when he suddenly found something rather interesting, she was rather ticklish under her right bra covered breast. This caused the side reaction of laughter and she accidentally bit on Harry's lower lip, sadly that made him jerk his head back in reflex, they looked at each other with lust.
Soon they turned right back to snoging and roaming again, however, Harry became a little bit more adventurous and cupped her left breast with his right hand, causing her to moan into the kiss (could be more pleasurable, if she didn't have her bra on...). Then he moved away from her lips, down towards her neck. While he was kissing her neck, he started to unhook her bra, they let it fall to the floor between her. Once the bra was taken care of, Harry could see Hermione's pink erect nipples.
Once he was done ogling her breasts, he went back to kissing her neck and started to cup her left breast again. This gave him an enormous moan of approval from Hermione.
