Paula proposed it to me 1 day. She's a good friend; not my girlfriend. And she seems to like girls more than guys. Paul and I talk 100% freely about everything, and we worked together for a while. Anyway Zoe, her friend is more like lesbian only. Still she was quite nice to me. We pre-discussed limits and boundries, like no penetrating Zoe at all ever. No problem. Zoe had short, gelled, dark hair, fair skin. Paula long brown hair, definitly dark complexion, nice curvey bottom, small breasts. The girls started with a little show for me, slowly undressing each other, "making out". We all snuggled on the bed together and Zoe started oral sex on Paula. I held, kissed and caressed Paula, and it rocked! The "forbiddeness" of Zoe mouth firmly planted down there, and Paula's face blushed red and her gasping for air overwhelmed with pleasure was a real turn on for me! Then Zoe with the best of intentions started blowing me! Then, God help me, I started to lose my hard-on because I started thinking "she really doesn't want to do me". So I asked her to switch back to Paula. Then I got the bright idea for me to penetrate Paula from behind, (vaginal) while Zoe worked on her clit from the front. This we did all 3 laying on our sides, the 2 girls in 69 position. It was my only such experience so far. Although she was quite sweet, somehow the butchness of Zoe made me feel ill at ease. Generally though it was quite fun. I haven't called them back. What have you tried?
