There's literally no stopping my Debs. This is a crazy story that even I can't quite believe happened, but trust me it did... We were at one of Debs best friend, Julie's house for a BBQ. It was on one the boiling hot days we've enjoyed this summer. I arrived after Debs as I'd had to work that Saturday and Debs had promised to help with some prep. I got there about 5pm to find Debs flushed, tipsy and in a very relaxed mood. She greeted me with a big kiss and got me a drink. I chattered to Julie as we caught up on middle-aged bullshit conversation. Debs then said "there's someone I want you to meet...Julie's son. He's moving in from next week from his Dad's which is in Leicester. He's starting a plumbing course at the local college". I was pleased as it would be another guy I could talk about to about guy stuff. We walked out to the garden and Debs called to him, "Joel". He had his back to us talking to others, he rose and turned in response. Then I realised why Debs was flushed earlier. Joel was a very good looking 18 year old. Tall and athletically build, with a big smile. He was also mixed-race with stunning dark brown skin and short cropped hair. I'd forgotten that Julie's first husband was a black guy. I said hello and we chatted for a bit about plumbing - he knew the basics very well. He was grown up, but still young. After a while he excused himself and Debs was awash with excitement. I asked if she fancied him, she smirked and said "he is hot isn't he. And so young and virile. Probably needs a mother figure to show him the ropes!" I noticed as Debs drank more, they flirted more. With even his hand in her leg at one point. Debs was dressed in a stunning short summer dress that was low-cut enough to show her full breasts off to their max! And a nice pair of heels. Joel had flip flops, tight denim shorts - that did nothing to hide his pert muscular bum. And a black tight vest - and again this only excited Debs more as she salivated over his large biceps, broad smooth chest and big shoulders! Julie then called me over and as she was so focused on the party hadn't given a second thought to what my wife was up to, why would she anyway? She was flustered saying they'd run out of chairs as more people had come than anticipated. I said I'd fetch some from our house just down the road. At that point Debs walked in asked what we were talking about. I explained, and Debs simply said "don't worry me and Joel will run and get them - think of your back!". Joel loitering behind her simply grinned. Julie was pleased; "OK, are you sure Debs. Thank you, you're a star! Joel will help carry them won't you my love - be good though for Aunty Debbie!". He simply winked at her. Julie paused and joked "look at him now! Taller than me, big strong lump. Do you remember when aunty Debs used to bath you when you were small?! You've grown up since then!" I laughed nervously - of course he's grown up since then - fuck me, it's obvious he's a now a big testosterone filled young man! Young lads like Joel, at his age exist to do only one thing! There's one thing on there minds, and that's to spunk! To drain their balls! Produce life through their virile seed! To reproduce! I could almost see this hunger and primal need in his eyes. Debs and Joel left. I returned to the garden and chatted to Julie's dad. My phone then bleeped - a what's app from Julie "guess what I've got in my mouth! Quick - come watch!" She wrote. I made my excuses and slipped out the side gate. Got back to our house and as soon as I was through the door I could hear Debs moaning and groaning. She was getting fucked! I sneaked around to watch through the crack of the door and I could then see Joel's pert brown arse bobbing merrily away and my Mrs dress pushed up to her hips getting a good seeing to from this young black stud. Debs was laying, legs wide on the sofa and Joel was on top. Debs noticed me and continued to entertain. She told him to sit on the sofa so she could suck his cock again. So he slid out and laid back on the sofa. I then saw his dick - this kid was one lucky cunt - no wonder Debs was moaning so much with that up her. He had a nice thick 8 incher of very hard black meat sticking up from his groin, rooted by neatly trimmed dark pubes and two large pink hairy balls. I also noticed how big and how pink his bellend was! He was clearly cut and so this only made his cock head look bigger - the rat head looked too big and heavy for the shaft to hold up! Debs sucked his wet, juicy fuck stick for all its worth and Joel was thrashing around like there was no tomorrow. Debs ran her fingers over his hairless young taught brown chest and Joel too was loving playing with debs very ample tits and nipples. "Fuck me, your mum is right, you even certainly grown up Since I used to Bath you!" Debs said between the hungry, deep wet sucking she was giving him. She rose and sat on his lap facing his a, "suck aunties big boobs you naughty boy". He loved it and was growing crazy! She even had to tell him to calm down "there's not really milk in them bad boy" he carried on regardless - sucking Debs milf glans! She took his cock and placed the huge bellend on her lips and they slid back together in one swift movement. The pace quickened and Joel's face was a picture of shear pleasure and Debs was one of lust and fulfilment. I knew he couldn't last much longer. I watched in a daze as his big balls flew around, they swung heavily with each powerful upward thrust. Hitting her bum each time. Sweat was running off both of them. All of a sudden Joel roared and said "I'm gonna cum!" Debs reply was of course one of resounding encouragement! "Yes! Fucking yes! Fucking cum you stud! Give me that black seed you stud! Fill me up!". Joel shouted back; "Here you are aunty! It's coming! Fucking tart - gonna fucking knock you up you old slag! Dirty aunty loving my big young cock in her!" He then roared and began his precious delivery. Multiple Sperm injections firing deep into her cunt. Saturating her insides. All those billions of healthy sperm swimming to my wifes unprotected (but probably past it eggs) from this young studs large testosterone filled testicles. I was mesmerised. As debs rose, Joel's spunks dropped out. Debs grabbed a tissue from the side and stood wiping it. "Fuck me how much have you put inside me? There's loads of the stuff!" She said to him. He laughed in a cocky manner and said, as he rose and started to French kiss her standing there "you've got a good weeks worth of spunk in there! My girlfriends on holiday"...he paused, kissed her and smiled, saying "Aunty". His cock was at half mast and still dripping the remains of his hearty ejaculation. Debs got down on her knees and started to suck his cock clean "bath time you naughty boy! Time to clean your well developed man bits" she said, smirking. I watched as she licked his obviously sweaty balls clean and then sucked the last if his cum out though his bright pink plum sized cock head. The main even was over and I thought I start being missed at the party and so I very quietly left. I was so turned on though. I got back and to be honest no one had missed me. I needed a piss and I thought, perhaps a quick wank to let off some steam. I mean I had just seen my wife getting fucked by a huge 18 year old brown dick. As I headed to the bathroom, I passed Joel's room. The door was a jar. I don't know why, but I went in. I think it's because he's had something of mine, I felt I had the right to be in his private space. His room was a typical lads room. Tit and film posters, XBox, laundry everywhere and a musk in air. I honestly don't know why I looked through his bedside drawers but I did. There in the bottom one, slightly badly hidden was a porn mag. I took it out. And flicked through it. Didn't know young lads still had these with wifi! It was a milf one and a good few years old by the looks of it. It was also a bit crusty with what I can only guess was his spunk. I was so horny I took my dick from my shorts. It was still pumped from the earlier entertainment! I wanked for a bit and after seeing what I had seen, and replaying it over and over in my mind I shot my load quickly, admiring the mag pics. I just needed relief. I sprayed my ball juice all over Joel's white bedding! fuck it I thought - He's shot his big load deep into my wife. I can cum on his dirty old bedding! It'll be dry in 10 minutes anyway. I returned the mag and went downstairs wiping the small remains of my juice of my hands on his dressing gown behind the door as I left. When I got back to the garden. Both Joel and Debs were there sitting in our chairs that they'd fetched, laughing and joking as they drank their drinks. It was like nothing had happened. Joel was clearly a bit sweatier than earlier, it was a hot evening anyway. I even overheard his mum Julie suggesting he should go and spray deodorant on himself. He seemed a bit shocked and headed towards the house, lifting his beefy arms up, sniffing each of his hairy damp pits enroute to assess them. It's a good job she wasn't able to smell his cock and balls - they'd hardly be spring fresh after what he'd been up too with his dick coated in dried milf fanny juice. When we were back home after, and I was fucking Debs very wet pussy, I joked about a brown baby and she simply winked and smiled, and said "you were part of it too. You witnessed his breeding. You loved watching this old aunty getting fucked!" That's all she said. We've not mentioned anything since, but as Joel's now living round the corner. She's now got young black cock on tap for the next time she fancies breastfeeding a well hung 18 year old spunk trumpet! And Julie has no idea that her best friend could have been carrying her sons brown baby! Sometimes they even meet for coffee or Badminton and she's literally still full from her son's generous gift.
