He says they are from Russia and their family was always very liberal about sex. They both grow up hearing their parents having loud sex in the next room and hanging out naked around the house. His sister likes to go to his bedroom and watch couples having sex live with webcam but the last few times things got much more active between them.

The guy is from Bolivia and wrote that his younger sister got married with a sales guy 15 years older than her, every time her husband goes away on business she likes to make him a visit. She comes to his place and they spend the afternoons together, since none of them has a full job. She's a noisy girl and the neighbours already start get suspicious about my sister's almost every day visits.

This is what really turns me on, having my husband and my sister-in-law watching me fucking my brother. They are not so sex addicts like me and my brother. We could fuck all night long while my husband and sister-in-law are satisfied with having sex a couple of times during the night, so just the thinking of having them watch me while I fuck my brother, makes us go even crazier.

Since they were kids they spent a lot of time alone at home. While parents were at work, they came from school and did everything for themselves during the day. His sister became interested in sex very early and it was with her brother she satisfied her curiosity about it. She also developed a big pair of tits that she always like to use to tease him when she wants something from him. Nothing changed. They still spend a lot of time alone at home but now they have more fun.
