You're just back from a business trip when your wife sits you down to talk. Recently, you'd made the difficult decision, together, to have her 'relieve' your son, in the face of him having broken both his arms. Not cumming was making him a little twirp, and since your wife has been giving him handjobs and blowjobs, he's been in a much better mood! Admittedly, they'd been spending a lot of time together, but you and your wife had decided on specific limits on what they were to do together, so you weren't too worried about it all. That is, until she told you she had something to tell you. You knew it was about this arrangement, so you asked her to tell you everything. You needed to know. You knew it would be difficult, but you didn't expect it to be hard. So hard. You were so fucking hard listening to your wife describe sucking and tit fucking your son! It was so wrong, but undeniably hot...and it didn't take long before your wife noticed how rigid you were, pressing against your pants as you urged her to keep telling you. She reached forward, pulling your cock from your pants as she described in delicious detail all the ways she's made your son cum...up to and including the way she, while you were away on your trip, encouraged him to fuck her. His own mother! Your wife urged your son to let her fuck him and take his sperm deep inside her pussy. You can hardly take it, listening to her tell you all about feeling your son's thick cock unload inside her...you cum in her hand, shooting hot ropes of cum that she slurps up greedily..."Ok sweetie, why don't you go get settled...I'm going to go check on that son of yours...see if he needs any...help."
