Robbie had just turned 18 but was still very small for his age and looked a lot younger and had always been known as little Robbie. He was a very late developer and had just reached puberty and was starting to take an interest in girls. At his all boys school his mates had been boasting about masturbating but he hadn't indulged in it himself - yet. In fact he had suddenly started noticing his 24 year old cousin Amy who lived next door with auntie Jean. It was coming to the end of the summer term at school and he knew he had to finish a project. The problem was that his computer had broken down.
His auntie Jean who lived next door and was actually his mom's twin sister had offered him the use of her computer and he was pleased to make use of it. He went round there at about 11 am and auntie Jean said she had to go out for a while. Robbie logged onto the site he needed and started his research. After a while he was thirsty and went to the kitchen to get a drink. As he walked in he saw that his auntie was doing some clothes washing and there on top of a pile of dirty washing was a pair of black panties.
He picked them up and loved the feel of the silk material. He rubbed them against his face. He had noticed some white marks on the gusset and when he put them to his nose they smelt wonderful. As he took in the aroma he found himself getting aroused. He rummaged further into the laundry basket and found more pairs of worn panties. He put them to his nose and smelt them all. Then he dropped his trousers and underpants and pulled on a pair of auntie's black panties. His cock was now very erect and almost poking out the top of the panties.
Then the worst thing happened as the door opened and auntie Jean walked in. Robbie grabbed his trousers but auntie had clearly seen everything including his erect cock.
Robbie just kept apologising, 'oh auntie I'm so sorry, it's very naughty of me, sorry.'
He started taking the panties off and was about to pull on his trousers and suddenly auntie said, 'Don't be silly Robbie, leave them on, you obviously love the feel of my panties.'
She went over to him and reached down and felt his cock through her panties and said, 'Oh Robbie you are so excited, I think auntie needs to take care of this, don't you?'
She led him to the lounge and sat beside him on the sofa and started rubbing his cock through the panties.
'Oh auntie that feels wonderful,' he said.
Then suddenly he ejaculated, he didn't know what had happened as spurt after spurt of hot white liquid shot out his cock. He had never experienced anything like it before and couldn't believe how good it was.
