My girlfriend and I been together for two years we live in a apartment. She understand my fetish with women lingerie and she allow me to wear them as long as I don't showing off in public. I walk around the apartment wearing lingerie all day when she is at work. The other day her dad came by for a visit I didn't know he was coming. I was in my lingerie in my bedroom and her dad walk in. He has a key to the apartment when we are gone, he stop by to make sure everything is okay. I was listening to music with my headset on and didn't hear him coming in. He was surprise see me in lingerie and said what the hell are you doing. I didn't know what to say but said I am so sorry and this is my fetishes. He said my daughter is dating a sissy I thought you were a tough guy. I said I am but this is one of my fetish. He said you must like sucking dick. I said I never try and I don't know. He pull out his dick and said suck on this. I wasn't going to say no, I am dating his daughter. I got down on my knee in front and sucking his limp dick then it slowly gotten hard. He grab my head start pumping his hard dick in my mouth. When he about to come he hold onto my head and come in my mouth until he was finish. He said swallow my come and ask me to lick it all clean. He said I am expecting to give him blowjob when his daughter is not around and dress in my lingerie. My girlfriend doesn't know I am sucking her dad dick and I am not going to tell her afraid she might get mad. I plan on getting marry to her it took me a long time to find someone like her to understand my fetish. I know I must take care of her dad needs but I am okay with sucking his dick. I am asking myself am I gay?
