l was now 18 and a half and it was two years since me and my mum had begun a sexual relationship, l'd filled out to quite a good looking tall, thin, but muscular man and so had my cock. The sex l had quite regularly with my mum had just got better as time went on. Sometimes we would stay in bed all day and night, trying different things, things that were new to her to, as she had a pretty much straight wam bam sex life with my dad when he was alive.
Sometimes we would hire porn films, then try out the scenes from the films. We tied each other up, spanked each other, had anal sex, tried many different positions, all sorts of things, all new to both of us, but it was one time when we had quite a dangerous quick oral session that led to a brand new experience!
l'd been away for the summer, doing a bit of travalling and was on my way back to see my mother. Although l'd had a great time l still couldn't wait to get back to her and feel that fantastic feeling of being in her, drinking in her pussy juices and seeing her suck on my now fully developed cock. l really wanted to go to the train toilet and masterbate, but l wanted to save all my cum for her, l hadn't told her exactly when l was going to be back and wanted to surprise her with a hard cock, she'd let me know whilst l was away how much she was 'missing' me.
l got off the train and jumped in a taxi to my mum's house, all l could think about was fucking my mum and l had as big a hard on you could in trousers. After l paid l got out of the taxi holding my rucksack to hide my bulge, lights were on in the house and l knew she was in. l let myself in and crept to the living room, opened the door, saw my mum sat at the table. l dropped my rucksack thrust my bulging trousers forward and said 'hi l'm back and look l'm very horny to see you!!'.
My mum looked a bit taken aback and started to shake her head and looked to the kitchen, 'who's that?' came a shout from the kitchen, o shit l thought my big sister. My mum looked at me and with a do something look, 'o hi sis, it's me, bursting for the loo, l'll see you in a min'. l turned and quickly went to the toilet to get rid of my hard on!
l came back down, they were both in the living room and l gave them both a hug. l t was strange and frustrating hugging my mother as quite often a hug like that would lead to so much more, but what could l do. My sis said she was cooking some food and did l want some she would make it stretch, o yes please l'll just go for a quick shower and get changed. All kind's of things went through my head whilst in the shower, what was my sis doing here, why was she here now of all times and how am l going to handle this l'm so horny. l hadn't had sex for ages!!! l got out of the shower and put on the only clothes that were clean, a tight t-shirt and a pair of baggy shorts and went down for dinner.
'o you're here, good it's ready' said my sis and we sat down to eat, l asked her what she was doing up, just visiting? 'well actually' she said 'l've finally told mum about Alison'. Now my sister, as l knew, had recently out of the blue shacked up with another woman, she had explained to me that although she still liked men, she had met Ali at a gay club and fallen for her. l looked at my mum who just smiled and said she can't wait to meet Ali and that she hadn't seen my sis this happy for ages and indeed my sis was very happy, even happier that mum knew.
We ate and drank some wine and l told them about my summer, eventually quite drunk my sister went to bed. Me and mum chatted for a while, then she said she should go to bed to, l stood up to give her a hug and we embraced. l imediately got fully erect in my loose shorts and pushed my hard on to her crotch. She told me to stop, it wasn't fair, l tried to kiss her but she pushed me away. l placed my hand between her legs and started to rub her. She tried to back away saying we can't, but l followed her never letting my hand off her until she was against the table.
l knelt down lifted up her skirt, pulled her panties away and buried my face in her wet pussy, sucking hard on her clit. As she pleaded with me to stop she also opened her legs up and took hold of my head pulling me in even harder till l could hardly breathe. l buried three fingers into her wet gaping pussy, rubbing hard the front wall of her pussy finding the area l knew made her shake with pleasure. l carried on licking, sucking and nibbling her clit and really quickly she was writhing and her pussy juices were dribbling down my arm.
She was trying to stifle her moans and gasps but she finally let out a string of quite load moans as she shook and thrusted her pussy onto my fingers and mouth, l knew l'd got her to where she wanted and my arm was running with her juices. l took out my fingers and pushed my mouth forward so l could drink in her juices, l'd so missed this. l stood up and and kissed her, sharing her juices with her. l then said your turn, she smiled and said, she knew she shouldn't but she couldn't resist.
We swapped places, she got on her knees, took out my hard cock, stroking it she took my end in her mouth, wraping her tongue around my throbbing end. Cupping my balls she started thrusting her mouth on my cock taking as much in as she could, sucking deeply. lt wasn't long before l could feel an orgasm rising, l knew it was going to be a big one, l'd saved up. l gasped as quiet as l could that l was going to cum, so she could stop sucking and start stroking me to cum on her tit's, which she liked. But she didn't stop, she kept on sucking and soon l was exploding a huge gush of cum into her mouth. She took in as much as she could, before moving away, my cock still gushing out more cum onto her face. l hadn't cum this much for ages and l'd never cum in her mouth or face before, it was fantastic.
