My sister invited a couple of her friends at the cottage and they partied most of the weekend. I showed up on the Sunday afternoon and joined them at the dock and spent part of the afternoon swimming and enjoying some sun. My sister is a bit older then me (4 years) and her 2 friends are nurses as she works at the hospital.

I went up to the cottage to get more beer and one of the girls followed me in - she was wearing a two piece bikini and she was quite hot. We cracked a beer and started having a conversation and all of a sudden, she tells me that she wants to blow me. I pretended that I did not hear but then she said it again but this time she said that "she would love to give me a blowjob". She asked me if I had a girlfriend and if I like getting blown ?? I was a bit shock as no one had ever been this direct with me.

I told her I was single and game as she reached for my swimming trunks and started undoing them. I could feel my cock getting hard and she pulled down my trunks in a rather swift motion. She got on her knees and started licking my balls and taking my member in her mouth. She told me that I had a big cock and she was really really good at sucking cock ! I eventually came a huge load of cum and she totally enjoyed every drop.

She told me that I reminded her of an old boyfriend of hers when she was young.

She got up and headed back outside. I followed her 5 minutes later after getting my witts back. I hope my sister never finds out but this was definitely the best blowjob of my life ;)
