Yeah, I would say those were a real orgasms!
Found a new one today:
Hot Summer Takes On A Massive Cockatron - Pornhub.com
Girl is just slightly unusual looking (big forehead, smallish eyes, almost looks like female version of Edvard Munch's "The Scream" with red hair), but she immediately becomes more attractive when the first O hits (the first of many, it would seem). I feel like I've seen a different scene with this same couple elsewhere in this series (and if I remember right, she was orgasming in that one also).
Wow that was hot. Who's the girl?
