Never thought this would happen

May and I have been friends for over 15 years. I have not found her attractive but she does have her moments. She thin and blonde but as a decent set of tits. She is a longtime friend of my wife’s family, so she is like a sister in a way. My wife was away on business and I had bumped into May at the store. I asked her if ahe wanted to hang out that next night. She said yes.
I arrived a little early and she was on her lap top on her couch finishing up some work when I got there. I sat across from her and looked at my phone. I lifted my head and noticed not only was she wearing a tight fitted shirt skirt but the I could see all the way up! She had nice tanned legs but the fact I could see all the way up her skirt, was awesome. She wore teal colored panties with a lacy part in front that showed her light brown bush. I could not help but catch a glimpse. Her legs were pretty wide open, which meant she had to know that I could see up there.
We left for food and there was casual conversation and light hand touching. Her legs were crossed underneath the table allowing her foot to massage my leg. She apologized each time but then did it again. We went to a movie and she picked the back seats in a pretty empty theater. She crossed her legs again and buried them into mine. I moved the arm rest and laid my hand on my leg. As the movie went on I brushed my fingers on her bare legs. She moved them away a couple of times only to move them back. I took the plunged and placed my hand on her thigh. She was still. I slid my hand up her leg slowly. Eventually I ran it under her skirt. She then unlocked her legs and opened them up a little. I could feel the area around us getting hotter. My hand went up her skirt and touched her panties. She slid down in her chair so I could get a better feel. It helped. I rubbed her wet panties, slid my hand down her lips and inserted one then two fingers into her pussy. May closed her eyes and let me finger her. Her pussy was so wet I slid another two fingers inside her. She held onto her arm rests as she prepared for an orgasm. She was quiet as she let a satisfied moan out of her mouth.
We left the movies and it was quiet and tense. Even though I made her come I could still feel the tension between us. There was little talk as I drove her home, just a few comments about the movie. I pulled up her driveway and I asked to use her bathroom. I didn’t need to go I just had to see if we could it further. I went to the restroom came out she was gone. I then heard her voice saying she was upstairs, which was her bedroom. I climbed the stairs and at the top of the stairs I saw her; sat on the end of the bed; naked. Her legs crossed and her hands to her side. She smiled and it was about the sexiest thing I had even seen. She opened her legs revealing that pussy and laid back on the bed. I knelt before her as she requested that I go as deep as I could. I pulled her close and then landed my face into her beautiful pussy. A little bush, a lot of deep layers. She withered with pleasure as I ate her out. After a while I stood up and dropped my pants. Got my hard 7” and pushed it into her. I pulled her even closer as I began to slowly penetrate her sopping wet pussy. I thrusted her with deep stabs as I held her legs up. She enjoyed every pump of my cock. I sped up a little and she lifted her head up and begged me to punish her pussy. And punish I did. I relentlessly slammed her over and over again until her moans sounded like she was begging for the sweet release. I didn’t dare change my position because she felt so perfectly snug g around my cock. I told her I was going to come
And she said okay. I pulled out and she sat up, and without a thought she opened her mouth just as I shot gallons of cum over her tits and over her face. We laughed and she drank my juice. I got dressed and left quickly hoping we would do it again
