*** This is a custom order; no names were used *** You go out with me, a seemingly sweet and sensual girl, and come back to my place for a little more fun. I tell you I want to get to know you better but don't want to move too fast, so we agree to just have a harmless JOI session where I watch you stroke from outside your boxers. Once I've edged you, I leave you wanting more as I step away for a second to make a quick phone call. In my absence, my twiin siister sneaks into the room where you're still stroking your hard cock, waiting for me to come back and let you cum. My siister is a bit more aggressive than me; she orders you to take your cock out and gives you a much more commanding and dominating JOI session until you finally cum. Now you're conflicted--do you stay with the more soft and sensual twiin, or do you prefer the fiery dominating twiin?
