Roll+hot to tell her what to do.

On a 7-9, she'll do it if you turn her on.

You move up behind your girlfriend's hot young sister, gently stroking her long dark hair. With your other hand, you reach for her tender little breast. Jessie gasps a little as you touch her through the fabric of her summer dress. You squeeze her teen titty until her little nipple gets hard. Jenna and Jessie keep kissing each other, moaning, while you pinch her little nipples. The two sisters keep kissing as you pull Jessie's panties down over her perfect ass. Jessie gasps a little when you give her teenaged pussy slit a long, slow lick. She moans into her sister's mouth when you rim her tiny asshole with your tongue. She tastes like heaven. When she is all wet and ready for you, you push your throbbing cock up between her tight teenaged asscheeks.
