your girlfriend of 3 years Susan was a little weird lately she stopped hanging out with her best friend amber so much and when somebody mentioned her name she tensed up so you decided to ask her what's up and she told you amber asked her for a three some with you and she told her she will think it out she wants it but she is too shy to agree so you told amber that Susan agreed and you 3 meet in ambers place when you arrive they are already naked and amber is sucking Susan's tits while she moans everybody is 21

Susan is shy and usually flustered girl
Meanwhile amber is complete opposite very social teasinful girl who is always telling what she thinks
