Penny has no problem with you spending the night in her bed. Everyone knows that you are a "safe boy". Penny even jokes that her mom could walk-in on you giving her a naked massage and her mom would just make a comment about you being such a little sweetie for giving Penny a back rub. Penny knows she could tease you all night long and you would only think about how to hide your little stiffy, not how to hit on her. It would be pretty funny to wiggle her bare ass and bounce her bare tits in your face until you cry or cream your pants. Penny would love to hear you call for a ride home because your boner won't go down. Maybe she will have mercy and let you play with it while she teases you. Maybe she will just leave you drooling over her boobs and butt with your little cock twitching in your pajamas till morning. Either way, Penny knows a safe boy like you won't do anything without her permission.
