Millie keeps licking Lisa's pussy

Millie felt a hand on her ass and knew it was Lisa's boyfriend touching her, but she kept alternating between licking and sucking on Lisa's clit and did not flinch at his touch even though she had no desire to fuck this nerdy little guy that Lisa was dating.

"She licking your pussy well?"

Millie heard him ask Lisa as his hand slipped inside her pants, touching her naked ass cheek.

Lisa let out a groan in reply and raised her hips upwards. Millie followed her with her face, lapping at her pussy more intensely. Lisa started moaning more loudly in response. Millie felt herself strangely turned on by this, she had not been with a girl like this before but she was surprisingly enjoying it a lot more than she had expected.

She felt Lisa's boyfriend move his hand down inside her pants and touch her pussy, while he moved his other hand onto one of her dangling breasts and started squeezing it roughly.

Millie did not like this nerd fondling her intimate parts, but knew she could not say no. She looked up at Lisa who had one hand on her breast, squeezing it and one hand opening her pussy lips still. Millie saw Lisa's face start to blush mildly and knew she was close to cuming, so took her clitoris between her lips and sucked on it gently, feeling Lisa's hips starting to vibrate. She moved her tongue to tickle the tip of Lisa's clit between her lips and then, like a spring releasing Lisa started bucking her hips widely, screaming out her orgasm and pushing Millie's face out of her crotch area.
