You start to finger her

Ann struggles behind you as you continue to push pressure around her neck.

"Aggh!" She screams as you can feel her fingernails digging into your heels.

You look at her pussy, noticing it glistening thanks to the oil and shrugs and with two fingers start to finger her pussy.

"Wha…what are you doing?" Ann screams behind you as her voice starts to become softer and less harsh.

You don't know if you are doing it right or not as you only finger a girl or two in college but that was about it and none of them were as experience as Ann is.

"Fu…. will you quit that." Ann screams even through her protests don't sound that convincing to you, "You…you are horrible at it…fuck." She mutters under her breath as her nails in your heels start to lessen and lessen with each thrust.

So with that said you decide to increase the pressure around her neck and make it three fingers in the pussy instead of two.
