I think the idea is that she was jerking you off, not that she was masturbating? But also, take a look at Aftyn: She started off doing "handjob sounds" by just rubbing her hands together with lotion but she eventually ended up actually jerking and even sucking a dildo off-screen. Maybe Maimy will follow suit eventually if she hasn't already (Ofcourse not, who am I kidding. But still a nice thought to have lol)
