dg on dg!
However, I think that both of them should have their hands busy at that point, the one lying down either places her hands on the joyrider's hip, or incase of dick girl, jack her off! (either going one or two handed wank)
I like the idea of her getting fucked and wanked off at the same time
I would rather see the lower one fucking, leaning over and getting her mouth fucked in her own fucking rhythm, instead of "just" wanking off.
p.s.: great work on that pussy!
