Lesbian liaison

I met Mandy at a party. Two months later we're still sneaking around. To my parents she's my math tutor. The rest stays hidden. Tonight the lessons start the moment our door closes. She sits on the edge of my bed in a white tank top, skirt hitched high, her blonde hair loose down her back. I kneel between her open knees and slide her panties off. Her skin tastes like warm lotion and salt. She pulls my hair when my tongue finds the right rhythm. Moans escape her and she presses her thighs tighter around my ears. Two fingers slip inside her while I keep my mouth on that swollen spot she likes best. She comes hard, shaking, the sound muffled by the pillow she grabs. After, she flips me onto my back, black hair framing her face as she straddles my hips. She grinds slow at first, then faster, making sure every slick fold drags over my clit. We move until neither of us can breathe straight, finishing each other with quick, wet fingers. Clothes stay half on. We know better than to undress all the way.
