my hands roved from her shoulders down to her butt cheeks , our mouths separated for a few seconds and one of her hands drifted around to the front and rubbed my erection , i slid one hand up from her waist to cup her breast , she pushed at my erection so it stood straight up , i gently pinched her nipple , wondering what i was doing , but it felt good and , despite a few misgivings about this peculiar woman , it felt so good i did n't look for a reason to stop .
