Came up with an idea where GF learns about BF's sexual relationship with his divorced mother. GF and son's mom get so turned on talking about son they start making out which leads to clothes coming off and the two having passionate lesbian sex. Initially a one-time fling, the two continued having lesbian sex while GF learns more about BF from his mom, including how his dad was noticably absent due to his demanding work schedule and multiple extramarital affairs. GF begins viewing BF less as a romantic partner and more as her own romantic son.
One evening, the two were making out naked on the sofa after another heated lesbian sex session when BF walks in on them. The two women have son get naked with them where he sat between them, his arms around their shoulders and their arms around his waist hugging him. Mom reveals to her son that his GF proposed to her and she accepted, his mom and now ex-GF are engaged to be married. GF tells him she loves him even more now and wants to be the best second mommy she can be, to fill the void of his bastard father
The two make it up to him by giving him a three-way kiss, his lips and tongue lashing with theirs. They have a passionate motherly threesome with one girl riding his cock and another riding his tongue, the two women cementing their love for each other... and their son
Son may have lost a girlfriend, but he gained a loving second mommy
