Alecto was pleased by her strategy and knew that Spencer would fail this time. It was not to say that her young student's lips and tongue didn't feel good. Alecto did have to exert her willpower to not press herself down against Spencer's lips. But, without doing that, Spencer had no chance to teasing her to climax before she reached it herself.
Reaching around her legs, Alecto grabbed Spencer's arse firmly and pulled them apart to make her hot, wet cunt more vulnerable to Alecto's tongue.
She moaned appreciatively as she tasted Spencer and she started to reacted beneath Aleceto. "Something wrong, Miss Fawcett?" she teased, sensing the other girl's approaching climax. "You aren't ready to admit defeat, are you?" Not waiting for an answer, she wrapped her lips around Spencer's exposed clit and sucked as hard as she could before letting her lips pop free a moment later.
