A Surprise for My Son

It's my sons birthday and he's away at uni so i decided to sky*e him. I decided to wear something sexy for him, he is really confused as to why i'm wearing this but I tell him I know it turns him on and I'm caught him watching me get undresses a few times before. I then go on to strip out my lingerie and tell him all about how i've been fucking his best friend Tyler. He is really confused and upset but I tell him not to be and I tell him that I know this is turning him on and he should get his dick out and jerk off over him mom. I then tell him Tyler is here with me right now and we are going to give him a little treat for his birthday. I suck and fuck Tyler while my son watches over sky*e. The funny thing is my son has a really small cock and I can't help but laugh. I compared Tylers cock to his and tease him about his small cock while being fucked by Tyler. At the end I tell Tyler to impregnate me with his cum so that we can give my son a new brother or sister! Includes: mommy/son role play, creampie, SPH, teasing, laughing, talking about taking a big cock and how you will never be able to please a woman with your small dick.
