Calista looked into Megan's dark eyes. She was filled with lust and excitement. Her lips quivered and her mouth watered. Megan was lost in her best friend's façade and thought about what would happen if…

She looked round. The teacher had gone. They must have been too lost in each other to realise that he had left. Their detention had finished 10 minutes ago. This was a sign for trouble.

Calista leaned towards Megan. She touched her hair, felt her soft lips. Megan blushed and let her. He hands moved down reaching her tender chest. She felt her top material between her fingers. She grasped her button, tugging it gently. Meanwhile, Calista had already pulled her top and trousers off, leaving her almost naked. She hadn't developed enough to wear a bra, but her boxers remained intact.

Megan assisted Calista in unbuttoning her shirt. Their eyes never left each other's sight. Now, fully naked, Megan leaned over Calista. Starting from her hips up to her chin, Megan dragged her soft tongue across her warm, tender body. Her nest target was the neck. Megan placed her lips on her friends shivering neck. She began to suck, leaving a small love bite just below her jaw bone.

Calista felt a throb down below. A sort of ache. She liked it. She reached for Megan's hand and put it down her grey underwear. Megan felt around for something poking out. Suddenly, Calista let out a loud moan of pleasure. Jackpot, she thought. Her hand started to feel more warmth and dampness. Slowly she started to pull off her boxers, past her knees, past her ankles.

She saw shaven, all neat and tidy, but her labia had a certain glisten to it. It was moist. Her clitoris had enlarged and was throbbing. Megan took her finger and shoved it into her hole with force. Calista groaned. She could feel her heartbeat rising as Megan's thrusting got harder and stronger. Megan added a finger to her hole and used her thumb to fondle her clit.

She got faster and faster until there was a final scream. A clear liquid jetted out of her urethra.

'I never knew you were a squirter,'

Megan smiled with glee. She had never been happier being covered in an alien liquid. From all the girls that she's been with, this has been the best.

The door opened.

'It's alright girls, you can go now,'
