Title and description amended to comply with the new t&cs- Step-Mommy is tucking you into bed as she does every night, making sure all the corners are nice and tight, and as she leans over, her full heavy breasts jiggle in your face, her nipple slips out of her top, and you get an erection immediately. Later in the night, you have a nightmare and go to see step-mommy. You startle her at first, but she welcomes you into the bed, and rolls over, exposing her big peachy butt. And that's when you start to masturbate. You stroke your penis looking at step-mommy's round cheeks. Step-Mommy can hear you, and thinks to her self 'surely he's not masturbating over me' and turns over, not able to open her eyes, and you ejaculate over her breasts. The next night, step-mommy asks you to join her in the bed, but this time she confronts you. Did you stroke your penis and ejaculate over her breasts? Do you want to do it again? This time she keeps her eyes open, and encourages you whilst you pump your penis.
