Helena began to move her hips slowly. She wouldn't jump on Andrew's cock, instead, she would rock back and forth for a few minutes and then start moving her hips in circles which made Andrew gasp in pleasure.
Little by little, Helena increased her pace and when she couldn't accelerate any more in those movements, she began to lift her hips a little and let them fall, getting Andrew's cock to plunge her deeper.
The resonant sounds of her ass contact impacting Andrew's pelvis each time her hips descended were increasing and with them her pleasure, so that Helena couldn't help but start moaning.
Her tits bounced with every movement and just like when Helena and Andrew's bodies touched, her tits also rang in contact with her own body, that alone was evidence of the speed with which she was moving.
