You finger her

you take your fingers and give them a lick before flicking and playing with Erica's clit.

"Mmm, oh mi god! that feels so good." Erica moans, as she does not try to close her legs, but instead spreads further for you. "Mmm, yes, touch me ... touch me."

Erica’s eyes grow wide as she feels you slide your slick fingers into her cunt, and begin to gently probe her insides.

"Mmm gaah!" Erica moans wantonly, as she humps against your hand. "Sooo good."
