Tutoring for the biology final

I'm studying for my biology final and I'm just having trouble understanding the sex organs!! I'm looking over my notes but it's just not clicking - how does an orgasm work?? Luckily, one of the senior boys is my tutor and he's really smart. He agrees that he can show me how an orgasm works by licking my pussy! I push his head deep inside and his tongue whirls around my clit while his finger pulses in and out of my hole. It feels amazing - I had no idea my vagina could be used like this! I'm so glad I befriended a total pussy nerd to help me study. It seems like he really knows his stuff as he works my dripping pussy to an amazing orgasm. I can't contain myself as I squirm and squeal in ecstasy. I finally got it, and I'm sure to ace this test now! At the end, the camera moves in close to my pussy so you can see how wet and puffy it is after my big orgasm. Maybe you can study it next time!
