After the barbecue ended, Kevin helped to tidy everything away and then headed for his bedroom. He desperately wanted a few minutes of alone time so he could process that days events. And there was plenty to process, firstly a magnificent blow job from his hot aunt, followed by the realisation that they had been observed by a hidden viewer. Then, his realisation that he rather liked showing his large cock off, and he had flaunted it to his hot young neighbour as he arranged with her husband to go round next day for some chores. The young wife had been well aware as Kevin displayed himself and arranged to visit next day, and surely knew what "chores" he had in mind.
Then his Grandmother, a beautiful, buxom woman had flirted outrageously with him, invited him round, praised his cock size and compared him with his father! Which meant that she must have seen her son in laws cock and judging by her comments, had enjoyed it too.
Then, to top it all, his own Mom had indicated that she was aware of Kevin's cock, and had no problem with him wearing 'loose' clothes in the house, but would prefer a bit more modesty outside, and especially in the vicinity of his sister.
Kevin lay back on his bed and pondered the days events. As he did so, he found himself stroking his cock through his pants, and decided this wasn't perfect. He slipped his pants down and began to gently stroke himself.
Just then, his phone vibrated on the bedside table as a text message arrived. It was from his Gran- she was going to have to cancel tomorrow's rendezvous but would reschedule asap.
Kevin replied that it was ok, but he was a little disappointed as he had held high hopes for the meeting. On the spur of the moment, he took a quick picture of his erect cock and sent that as well.
Kevin carried on jerking himself gently, there was no hurry after all and his phone buzzed again. This time it was a video clip from his Gran.
It was very simple, just a close up of her face, mostly focussing on her mouth. She smiles, licks her lips and then blows a kiss. Simple, yet very very suggestive. Kevin fully understood the message and began to stroke himself a little harder.
Today had been amazing already, and now he was jerking off to his Gran's picture, in the confident knowledge that pretty soon her lips would be wrapped around his big hard cock!
He was really getting into it, when he heard footsteps coming upstairs. It was his Mom!
Frantically, he grabbed a pillow and pulled it over his lap, concealing his erection! Just in time, as him Mom walked without knocking into his room. She sat on the bed and prepared to speak, then hesitated.
She saw Kevin, sitting up in bed, with his trousers down around his knees and a pillow in his lap. It didn't take much to figure out what Kevin had been doing and she smiled at his discomfort.
At the same time, Kevin realised that, based on her remarks that afternoon, she would be pretty relaxed with him wearing less clothing and perhaps exposing himself from time to time.
Their eyes met, as Kevin relaxed, drew a breath and calmly lifted the pillow from his lap. His cock grew even bigger and harder, if that was possible, as he exposed himself to his pretty Mom.
She simply looked down at his cock, smiled and started to ask what he fancied for dinner, as if nothing had changed.
Emboldened, Kevin once again wrapped a hand around his cock and started to stroke himself. At first he kept his eyes on his Moms face, half expecting a reaction but when none came his gaze began to rove and very soon narrowed in on her chest. She had large tits, and he could clearly see their size and the outline of her bra through her thin top.
Mom stopped talking, and just watched as Kevin jerked off to her breasts. Kevin could feel the tingle starting as his climax approached. He carried on and, without warning his Mom, starting to ejaculate streams of hot cum into the air. It was so powerful he thought he might die as his hips rose from the bed and his cock jetted rope after rope into the air and onto his naked chest.
When eventually he had finished, he fell back onto the bed panting. His Mom looked at him, particularly his cock and the pools of cum on his stomach. She looked down at herself and noted with some surprise that not a drop had hit her. She was about to leave the room when Kevin stopped her by speaking clearly and firmly. "Mom- go and fetch me some tissues please, I think we need to clear this up, don't you?"
