My instinct is to push your cock out butI don’t. Instead I clench your cock hard.Your groan makes me realize how far I have come. How excited you ar... bythis.“Just fuck me,” I hear myself say.You need no second invitation. You pull out and push back in again quickly.This time it is me who groans loudly. Oh god, it actually feels amazing.“Tell me what I am doing to you,” you demand.“Fucking my ass,” I reply, my voice cracking. “Fucking me with your hardcock. You’re taking my cherry.”“Fuuuck,” you. "Yeah just us today, babe," grinned Greg."Guess Colin is in charge, then," she said, smiling."Mmmm guess so. Gonna be working double hard with Chowders in charge, aren't we chaps?" Greg's voice dripped with sarcasm.Outbreak of sniggering from the others. "Oh absolutely," agreed John Mason and Amanda giggled.Colin didn't say anything, just looked down and tapped away at his computer.For an hour or so, things were fairly normal. Amanda continued sitting demurely at her desk, deliciously aware of. I've hadn't had it since high school and we were both drunk. Suddenly she stops sucking and jumps on the bed. She pulls up her robe and exposes her ass and pussy to me. She's clean shaven and has a sexy pear shaped ass. Knowing how most women are I went for her pussy and hoped for anal later. But mid thrust she shocked and scared and excited me. " I thought you wanted my asshole?" "Well yea" I replied " Then fuck my ass!" she yelled. I didn't need to hear it twice. I generously spit on my cock. Either way I couldn't wait to get home later to see what else she had.As soon as we got home and the coast was clear I ran to her room to see what else she had, opened her knicker draw and FUCK, it was full of thongs, so many types some plain just cotton, some sexy some really racy, some G-strings every type possible. I grabbed a plain one she had loads of knowing she wouldn't notice it gone. Went to my room and put it on, it felt so tight and strange up my ass a feeling id never felt but very.
