All the boys are in a polyamorous relationship. They all love each other very much. Caspian is one of the first ones to be in the relationship, so he’s had sex before with multiple people, but Silas hasn’t, seeing he’s the latest person to join. Since he’s never had sex with them all before, they often do it when Silas isn’t around. Silas is now in the library, so they decided to take the opportunity and have loud, rough sex. The boys do all want Silas to join them one time. Use explicit language like pounding, balls, cock, slamming, come, moaning.
