My Friend Was Out Of Commission, So I Went For My Friend's Girlfriend And I Fucked Her Without Waking Up My Friend, And When She Tried Desperately Not To Scream With Pleasure, It Got Me Super Excited

I was drinking with a couple friend when the guy got drunk and passed out. I started messing with his girlfriend, and while she said no-no, she let me kiss her, eat her out, and give me a blowjob... She's trying to hold back her voice so she doesn't wake him, but it feels so good she's letting moans slip out.
