The cheating girlfriend [MF]

Ill just start off by saying i was with my girlfriend for 2 years. we started off great but in the end things didnt end so well. we met on holiday she was my friends sister and their was always just something about her she was curvy in all the right places her arse was amazing big and peachy and she was always slightly tanned which i liked. Her tits weren’t the biggest but they fit her frame and were still a handful i thought our sex lives were okay she didnt always cum but i felt like she enjoyed it.

So towards the end of our relationship she started acting different she was more moody and didnt really speak to me as much. This was when she started going out with her friends more she did live with me at the time but i worked alot and wasnt always home. So one weekend i come home and she had been out with her friends the night before and three of then were sat on my couch with a blanket on them her best friend to the far left her in the middle and a guy on her right i had never seen this person before she claimed that they were friends he was tall and quite skinny where as i am quite a big build not that tall but stocky.
