(This was a custom video I was invited to collaborate on! I can make one for you too!) My girlfriend walks in demanding to know what's going on. I try to tell her it wasn't my fault but she heard me yelling Emma's name. She pulls Emma's hair and yanks her off the bed. Emma tries to make excuses but is beaten down with belly punches, low blows and nipple pinching. Emma slumps over, apologizing and begging for forgiveness, my girlfriend turns to me, asking how I could be so pathetically stupid to fall for this. I apologize too we are both groveling at her. My girlfriend has Emma sitting on the corner of the bed, with her legs open and her hands tied behind her back. She is gagged and has a vibrator shoved in her pussy that is constantly buzzing. Emma is begging for it to stop but can't help feeling orgasms every once in a while. My girlfriend still has me tied up, even though I'm begging her to let me go. She's so mad at me and wants to have fun after a long shift. She smacks my balls and cock while I beg for forgiveness. I call her mistress. She starts stroking me, saying she understands I’m so weak and pathetic, that’s what makes me a good submissive. My girlfriend has her way with me. She bounces her butt on my belly, pulls and twists my nipples, bites my chest and belly, fingers my belly button, claws my stomach, slams her belly onto mine, slaps my balls and kisses me. Emma is still experiencing orgasms, but begging for it to stop with her eyes. My girlfriend is stroking me and using her mouth making me beg her to let me cum. She makes me swear loyalty to her, that I’ll only ever be her slut, I’m swear yes, she asks “yes what?” I say yes mistress, she makes me promise to be good but denies my orgasm. She walks away, But comes back in to dominate Emma and teach her a lesson on what a true dom is.
