Friend with benefits

I don't know why I'm writing this, maybe it's a way to clear my conscious or to brag, either way this would be something I share with my best friend, but since this involves her I'll share this with you.I met my best friend, Gia, around 3 years ago. We worked together, I'm openly gay and I knew she was in the closet. I was immediately attracted to her. One night we started talking about sex and she told me how her girlfriend never sexually satisfied her. Gia told me what she liked and I knew I had to satisfy her. One night I decided I had to fuck her but we never had time alone together. Finally, her girlfriend was going out of town and my girlfriend was home sleeping, sick with a cold and medicated. I knew this was my only chance. I drank a couple shots of tequila for courage and found myself at her front door. Gia answered the door in only a T-shirt and shorts she seemed surprised to see me but without saying a word we both knew what was going to happen. Gia stepped back to let me in the door. I stepped close to her and at first softly kissed her; since she didn't push me away I parted her lips with my tongue and started to explore her mouth. I was relieved when she gave me her tongue. I immediately got wet, and had to have more. I reached down and felt that her nipples were hard, I stared circling her nipples through her shirt with my thumbs. I moved my mouth down to her neck and started sucking but not to hard because I couldn't leave any marks. We fumbled to the couch and I pulled off her shirt. Gia straddled my thigh and started to grind against it, slowly at first. I started to circle one nipple with my tongue and the other with my thumb. Teasing her. I squeezed one nipple hard and at the same time I bit down on the other. She moaned and started grinding harder. This seduction was going to be on my terms so I pushed her off of me. I pulled off her shorts and sat her down on the couch, I opened her legs and saw her clit was red and hard and begging to be sucked. I teased her clit with my tongue and put my lips around it gently sucking. She started pressing her pussy against my mouth and I saw how wet she had gotten. I put one finger inside her; it felt so wet and warm. I had to put more fingers inside. While sucking on her clit I was penetrating her with three fingers. I was going deep and hard. She grabbed the back of my hair and pressed my face into her pussy. Gia started crying out and knew she was about to cum. Gia had once told me that she never had masturbated because she didn't know how and she didn't think she ever needed to play with herself. I thought differently. I thought I would give her a crash course on masturbation. I left her warm wet pussy and I could tell she was confused and pissed. Without saying anything I grabbed one of her hands and guided it to her pussy and had her put her fingers inside herself, in and out, in and out, and in and out. I knelt down beside her and stared to squeeze her nipple and whisper in her ear. I told her how next time I was going to tie her up and fuck her. Gia was a quick learner because she came almost immediatley. I felt kind of cheated so I knelt down in-between her legs again and licked. I got cum on my mouth and lips and I wanted her to taste herself so I straddled her thigh and kissed her hard and deep. I knew she could have cum again but I fulfilled my fantasy. I jumped off of her and kissed her goodbye. Now I'm just waiting for her fantasy.
