Wait for an opening

You decide to sit and wait for an opening instead of forcing yourself in so you start to enjoy the show for a short while.

Cecile pulls away from Frost and pushes her backwards, straight onto an armchair and starts to kiss her again. Not too long later Cecile starts to work her kisses down the other woman's, snaking down across her tits and further past her stomach until she made it to her lap.

Cecile looks up at Frost causing their gazes to meet as she gets on all fours in front of the chair and spreads Frosts legs apart, beginning to lick at her pussy. Frost moans at the sensation, causing your dick to stand to attention and you realize you've got your opening now.

You walk up beside Frost who is in a slight daze from the pleasure and as she moans again you pull her mouth around your cock, making her gag briefly as she adjusts her breathing. Her mouth around your shaft feels amazing as she starts to use her tongue to work it, which only gets better as you start to thrust. Time seems to slow down for the next few minutes as you're overwhelmed by the feelings Frost is giving you but you can concentrate just enough to notice Cecile, who looks up at you and winks. Accompanying Cecile's wink is a gesture towards the back of her as she spreads her legs, awaiting your reaction.
