Your mom invites you into her bedroom for a little talk... You aren't in trouble, she just wants to make sure you're prepared to please your girlfriend! She reminds you that it's nothing weird or sexual, only educational, as she plays with her tits for you, asking you to show her how you stroke yourself. She soon takes over, lubricating your cock and giving you a thorough hand job while teaching you how to edge yourself and make you last longer. She seems hesitant to keep going further, but plows on anyway, eventually sticking your cock in her mouth! She reminds you to stop as you get to the edge, but it gets harder and harder to hold back your cum while she slobbers on your dick. Finally, she wraps her huge tits around your throbbing cock, pumping vigorously at it until you explode all over her tits and her bed. She reminds you not to tell anybody about your sex ed lesson, but she might be calling you back in soon for future hands-on education.
