It wasn’t usual for me to come home straight after school. That’s probably why my sister wasn’t expecting me to walk into my room when I did. I sure didn’t expect to see her naked on my bed with my underwear over her head, getting her pussy licked out by her best friend Andrea.
Andrea was also buck naked, kneeling half-on and half off the bed. She was frigging herself with on hand, and grabbing Amy’s tits with the other. Amy (that’s my sister) was lying on her back on my bed, pulling Andrea’s face towards her cunt and moaning, while the other hand kept rubbing my used panties all over her face.
“Oh, she smells so good!” Amy said, “I wish I could lick her pussy and ass for real.” Andrea just grunted and kept eating Amy’s love hole, fingering her own sloppy channel with her long fingers.
I stood there, shocked that my sister was a lesbian, and doubly shocked that she fantasized about me. As I looked down at Amy’s body and Andrea furiously licking her snatch, something came over me, a desire to be involved in their sexual play. I knelt behind Andrea and inhaled the aroma of her gash. It was intoxicating. Without any hesitation, I reached out and placed my hand over Andrea’s on her cunt, feeling her juices running through her busy fingers.
Andrea looked back at me, wondering who had joined them. As she looked back, I brought my fingers to my nose, smelling her pungent fluids up close. Amy grabbed Andrea’s head and pulled it back towards her juicy slit, unaware that I was there. Quickly, I tore off my clothes and went to stand over Amy’s head. I pulled my used panties off her face and squatted down with my pussy over her mouth.
“So, you horny little girl,” I said, “you’ve been stealing my panties to lick them. Well, now you can lick right from the source.”
It took less than a second for Amy’s lips to latch on to my cunt lips. God, that felt good! She licked my slit eagerly, driving her tongue up inside me, nibbling on my clit, running her fingers all over. She began to trail her tongue all over my labia, in ever widening circles. Then she slowly licked down towards my ass. Her tongue was like a wriggling, warm, wet finger, and she began to probe my anus with it. I relaxed until she was able to get the tip in through my tight sphincter. She moaned with delight, I moaned with pleasure, and Andrea moaned with the sheer ecstasy of seeing her lesbo lover tongue my asshole.
Amy was lying down with her legs hanging over the bed, and I was squatting over her mouth, facing her feet, watching Andrea’s glistening body. Andrea had been on her hands and knees on the floor to lick Amy’s clit, her ass waving around as she fingered her own pussy, but she now straightened out to rub her sticky slit against Amy’s. She reached out to run her fingers through my cunt hair as my sister continued to lick my ass. Andrea soon found my clit and began pinching and rubbing it, driving me into sexual ecstasy.
I reached down to Amy’s tits and began rubbing and fondling the huge globes. Amy reached up to cup Andrea’s breasts, and then Andrea leaned forward and began to kiss and nibble my erect nipples as she ground her juicy box against my sister’s. Amy’s tongue continued to probe my rectum, and it felt wickedly erotic, especially with Andrea’s finger buried in my snatch. I knew I wouldn’t be able to hold out much longer. Andrea sucked on my nipples so hard, I thought she would suck them right off my boobs.
