Maybe a bit more

Frank almost growls, “I’m so horny right now.”

Sandra pulls him in for another kiss and can feel his cock pressing in to her. “Well you may be having issues finding a date, but at least one part of you knows what to do around a woman.” Sandra slide her hand down his chest and cups his crotch. “That is quite the reaction there.” She gives it a slight squeeze and he thrusts against her hand.

Sandra looks around. “Shh. Quietly now.” She deftly gets his pants open and slides her hand in to his pants. She gasps as her fingers wrap around his thick shaft.

Frank groans, his hands grabbing her breast through the tight outfit.

"Ooo, you are a thick boy." Sandra starts to stroke his cock in his pants, keeping a light pressure so he doesn't cum too quickly. "Is this what you wanted Frank. Has my tight costume made you want your cock touched all day?"

"Uh huh."

"Are you going to cum for me? Are you going to cum all over my hand for me?" She tightens her grip a little and speeds up the stroking. His hands are pawing her breasts roughly and she is loving the wantonness of it.

Frank starts to grunt and she grabs his head, bringing him in for a kiss to keep him quiet. His hips thrusts against her hand and then she feels his cock pulse and the hot cum shooting on to her hand, wrist and forearm.

She releases his head and breaks the kiss. "That was so hot." She extracts her hand from his cum filled underwear and licks her hand and arm clean. "You taste so good. Now remember, we can't tell anyone about this. OK?"

Still on his endorphin high Frank nods. Sandra kisses his cheek and then gets in to her car and rushes home.
