Well as you know just a short time ago me and my oldest younger sister started having sex. Well my sisters came to visit me a couple weeks ago and as soon as the two younger girls went to bed (half sister is 15 and step sister is 16) my sister started giving me a blowjob. I was loving it. It felt so great. We were in the living room watchin a movie. The lights were on and everything we made no attempt to hide it. Well my half sister got up to get something to drink and walked in on us. She didn't say anything right away she just watched for I don't know how long before I noticed she was there. I saw her and was startled. She said don't mind me go ahead and continue. She went on to get something to drink and went back to bed. My sister went on with the blowjob and made me cum in her mouth and swallowed like a champ. I told her to talk to her and convince her not to say anything. The next morning she taked to her and then took my step sister out to get a dress for the fall dance. My half sister came in the living room and sit next to me. She started to tell me about her sexual experience. She had hadsex with two guys already and both times she hadn't gotten off and it was disapointing. The she told me that our sister had told her that I was the best sex she ever had and thats why she couldn't resist doing anything with me every chance she got. I was begining to wonder where it was going but she didn;t make me wonder to long cause she asked me to have sex with her. I wasn't sure but before i could respond she already had her hand in my pants kissing me on the neck. I thought well if it will keep her from telling anyone what she saw I would do it.... She undid my pants and started sucking on my rock solid dick. It had felt as good as my other sister. she may have only had sex with two guys but I was sure she had given plenty of head. I stopped her and told her to take off her clothes and lay on my bed. She went back to my room and striped down. I went back there and took my clothes off. She is about 5'2" and 100lbs she is fine as hell. Small boobs but like small ones. I started at her feet and kissed her all the way up to her bald pussy. I could tell she had just shaven. I didn't care i started to lick on her clit. It didn't take long for her to arch her back and scream in pleasure. She came and I licked as much of it up as I could. I continued to kiss my way up her body making my way to her nipple where I nibbler on it a little and sucked on it some. I rubbed my cock around on her cunt some and tried to ease it in and it was a very tight fit. She loved every inch. I slowly started to fuck her in and out and she started to get into it by yelling faster and harder. i was going as fast and as hard as I can and it went on for about 10 mins ahe came four more times. I was getting about ready to cum and I asked her if anyone had ever came on her face before and she said no. I asked if i could be her first. sha replied with you were my first orgasm so why would I deny you this. I pulled out and moved up to her face while stroking my wet cock. she stuck out her tongue and licked the head a few times and that was it I shot a load all over her face and in her mouth. She didn't flinch or anything just closed her eyes and then swallowed that in her mouth and then licked my cock clean of mine and her cum. It was great. I still have sex with her.
