I'm your little sis's best friend spending the night. She told me to come borrow your tablet when I walk in and catch you jerking off. I notice how small your cock is. I've listened to my friends talk about their boyfriends huge thick cocks, and was worried that all cocks were that huge and it would hurt when I had sex. I'm relieved that they come small. I probably would barely feel it with my tight virgin pussy. I tell you to keep stroking while I play with myself under my skirt.
