Rachel's son Billy was an introvert, and finally having had enough of his moping and his pathetic attempts of popularity she had a long chat with him about how he could get out there and come out of his shell. Billy gave it his best but to no avail; he failed. Billy loved his busty, curvy mother, and he compared her to the young females at school. No one held a candle to his loving mother. She oozed sexual presence, and he thought about her day and night jerking to her big tits and round ass. Rachel came home early one afternoon, and she didn't know Billy was home attempting a good jerk session. Rachel walked in his room to witness his poor stroking technique she knew she had to assist. Rachel changed into sexy lingerie sure to make him lose his mind and his load. The next hour was spent teasing her sons cock, edging his sperm to the surface and denying him the pleasure of release. Over the next few days Rachel spent teasing his cock, coxing him to the edge. Her plan was unfolding nicely. His cock was responding. Rachel entered the bathroom where she jerked, titty-fucked, blew and fucked her son silly until she yanked it all over her bouncing Round tits. Billy had found a new confidence but still no need for the younger females; only mothers coxing would satisfy him now!
