Roll+hot to tell her what to do (+1 submissive)

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

Jessie blushes cutely. Jenna just smiles at you, but she doesn't seem mad about the idea. You lay one hand on her smooth thigh, pulling her closer to you, and kissing her face, her lips, her neck. You stroke her hair, and kiss the sweet spot under her ear that always makes her moan, and you whisper,

"Let her watch, sweetheart. Let your little sister watch how you suck me off."
Your hand on the back of Jenna's head, you gently push her down toward your crotch, and look over at her sister. Jessie is staring at the two of you, shocked, embarrased and excited. Jenna slowly unzips your pants and takes your swelling cock in her hand.
