Bringing A Hopelessly Silly Classmate Back Home

At a drinking party, the girl I've admired since school gets wasted and misses the last train, so I take her home saying, 'Let's rest a bit.' Every time she turns over, her sweaty, excited cleavage, her stockings-clad thighs, and her panty shots are exposed. Unable to resist, I start messing around, and she—awake since when?—seems to have gotten horny from the alcohol and starts passionately demanding me! I cum inside her as is!
