The stratford 80 lockdown with a bismark attachment is a two part maneuver. The stratford 80 lockdown part consists of putting the girl's legs behind her head and tying them together with her panties. Following this, you pull out, punch her in the nose, smear the blood, and then cum on her face, thus completing the bismark attachment.
So i was doing this chick last night and decided to throw her into a stratford 80 lockdown with a bismark attachment. Lets just say, i don't think she'll let me near her again, ever.
