Just to be sure, I moved Sarah and Karyn into Karyn's bedroom. No more cheers and for better intimacy, I changed into a furniture.
Falling into the bed, the two girls start to undress each other and Karyn begin with two fingers into her pussy for Sarah's great pleasure.
This time, it was sure, Sarah was a lesbian with a crush on Karyn. But I didn't leave mesmerized by the spectacle in front of me. It wasn't like the pornos, it was sensual and in comparaisons, porn looked like monkeys playing with their anatomy. Karyn and Sarah licked and fingered each other pussy until they orgasmed. And they did that all night and still was doing this when I waken up.
Of course the morning, I had a massive erection. No porn mag today, I jerked off just remembering the scene I've just seen.
Later I wait at school for Karyn to talk to her about what to do with Sarah. I brought the stone with me, just in case.
