[This was a custom request] You return home from work a little earlier than expected and are completely shocked to see the teen babysitter trying on your wife's lingerie. She is visibly embarrassed about being caught but explains shyly that her step-mum won't let her buy sexy underwear yet and she simply wanted to see how she looked in it. She asks if it suits her more than your wife and, seeing her tight young body, you have to silently agree that it does. Her confidence starts to climb when she notices that you're hard and she admits that she's always had a bit of a thing for you, despite the age difference. Your wife is still at work, so she questions if you'd like to see what her young, fertile little body can do. She knows she could make you feel good. She begins to ride your cock while talking to you about the your huge age difference and whimpering that she's never felt a big grown up cock like yours, stretching her so much. You're never felt a pussy as tight as hers either. She plays with and licks her nipples while sliding up and down your cock, still wearing your wifey's panties and getting them all wet with her juices. She rides you until she cums, soaking your cock and balls, and then asks if you'd like to pound her now and just use her until you cum. She lays back and spreads her wet pussy while you fuck her hard, watching her beg and moan for your cum, telling you that she's so young and fertile for you. When you cum, it's explosive inside her. You'll have to put your wife's cum covered panties in the washing machine as soon as you can... she'll be home very soon.
