On my 50th b'day, my mother-in-law walked in on, my wife naked, with me naked over her knee on our living room couch, as I was getting my b'day spanking. The women talked, without my wife missing a beat. When she finished, my mil, wanted to wish me a happy b'day too, so over her knee I went. After she had me doing a lap dance across her lap, she asked my wife what other family traditions do we have? My wife told her, my nipples, are just as sensitive as any woman's & I love to have them sucked on, pinched & bitten. So my mil, flipped me over, noticing I was getting stimulated from just my spanking, saying to my wife, "Wow, little markiee, really likes getting spanked, doesn't he". "Yes he's always gotten turned on from a naked spanking over my knee, he also said he likes feeling the weight of my heavy worm breasts resting on his back, helping to hold him down". My mil then took her top off, telling me to suck, as she did the same to me, then biting, watching my man muscles reaction. She then asked my wife, if there was anything else we do. "Yes, when I've sufficiently teased him, I blow his candle out for him". The next thing I knew, I was getting a BJ & handjob as she squeezed my jewels, as I erupted as she lifted her head & speeding her hand up, until I couldn't hold off any longer. They both laughed, clapped their hands & singing me happy b'day, as I lay back limp, across my mil's lap. They both get me for the day on their b'days. Both strip me, spank me, keep me naked for the day, spank me some more & have their way with me.
