>>21339626How old are you anon?
If acceptable age difference then chill or smoke with them, when sister steps out, her friend will probably be down anyway. Confidence is key and friend’s hot older brother is common fantasy. Especially as a 16 year old Stacy with limited brain dev.
Also if sister is cool tell her you want hot booba friend and to slide it in. “My brother thinks you’re hot.” And go from there.
