Lisa feels something against her skin

Something woke Lisa from her slumber. A squishy sound next to her where Sara lay. The mattress rocked slightly, in time with the sound. A warm foot caressed her leg. Suddenly she felt something pull on her nightgown, exposing her skin to air. Lisa held her breath. Her brain had a hard time putting together the clues. She felt Sara's movements – restrained, but easy feel pushed against eachother as they were. The girl was touching herself! Under their shared cover! While... also touching Lisa?

Lisa was unsure of what she should do. She should feel disgusted, but... she felt ... warm. The nightgown was pulled up over her behind and without thinking about it, she moved so that the fabric could be released more easily.

A hand was placed over her bare buttocks and squeezed lightly. Lisa could not help it. Slowly, slowly, she brought her hand down between her legs. Sara's hand squeezed harder over her bare ass and she held back a gasp. Lisa pulled her fingers like a feather over her slit, feeling how the moisture stained her fingertips. There was something forbidden about touching oneself - seldom pronounced, but still well known. It was an insult to God, a submission to your basic carnal impulses. Humans were more than that, more than animals. God had given them the will and strength to resist such temptations!

But... it felt so good. And ... Lisa had to admit it to herself, but sweet little Sara next to her, squeezing Lisas' buttocks, made it even warmer.

"Oh!" Sara panted and Lisa felt something wet over squirt over her buttocks. The hand let go of her butt and Lisa tried to lie still, still with her fingers buried between her legs. Sara sighed loudly and the mattress shifted as she got up. Lisa heard her step out of bed, open the door and sneak out in the hallway outside.

Lisa felt the heat from her pussy, felt it pulsate under her fingers. She just wanted to start rubbing, giving in to her sinful desire. But she held back, forcing herself to be the docile christian she was raised as.

She lay on her back and stared up at the ceiling, feeling how the mattress got wetter under her ass, where Sara had sprayed something on her. What had it been? And also... what had just happened? Lisa thought of the bath earlier during the day, when Sara had started massaging her breasts. Had it been more than something innocent? Had Sara ... had a desire for her?

And where had she gone?
