Yep! What's really hot is to finger her clit while another guy is screwing her making certain you can feel his cock sliding in and out of her pussy. Also super hot to use first two fingers to make a "V" over her pussy then provide a "finger-vise" to that big cock. Have often given advice to the screwer; "Ok, now really pound her; she really likes to finish with really hard fucking".
Have Fun!
