Son is spying at the end of mummys bed and she is making noises and touching herself. Mum notices and gets embarrassed and asks what you are doing there. Mummy wants to try expanding herself so tells son to get on the bed. Mum explains that adults have playtime like kids with toys but adults also do it together. Mummy hasn't had playtime since daddy left and really needs it. Mummy tells you to stay in her bed as a treat tonight, kisses you and rolls over. Son, trying to make mummy happy like she explained, sticks his dick in her hole. Mummy turns around in shock and has to explain mummy and son play is different to mummy and daddy playtime. Mummy starts to wonder if they can play like that? Eventually gives in and starts rubbing son's dick, sucking it and fucking him. Before she fucks him she teaches him how to lick her pussy and gives you a close up pov while son makes her orgasm hard! Son gets worried about the mess he put inside mummys hole but mummy reassures him and explains every playtime has a clean up time.
