I have a sweet little twin sister who is still a Virgin, but i know how desperate she is gagging for cock! Which i confront her about! She's a little shy and embarrassed but she admits she would love to have some fun with her first ever cock! I even tell her that i have been noticing she has been checking out my boyfriend. which i know she thinks he is so hot, and would love to have some fun with him.... so i get straight to the point with her, seen as she is still a virgin and she has me as her sister "the pro cock expert slut" I tell her i think she should blow my hot boyfriend, she freaks out at first but once i explain ill be here with her , telling her she is doing such a great job sucking him... she changed her mind and was up for sucking his cock and getting a face/mouth full of his cum.
