My mother-in-law (6'3" 220 lbs.), started spanking me (5'10" 165 lbs.), like this on my 50th b'day. My wife & I were in our b'day suits on our living room couch as my wife was giving me my b'day spanking, when in walked my mil. She started laughing & teasing me about being a naughty little boy, & this being a whole different side of me that she hasn't seen before, but hoped to see a lot more of in the future. After my wife was done with me, my mil said she too wanted to wish me a happy b'day, & over her knee I went. She spanks just like this, the same sounds fill the room as her palm contacts with my naked hiney. It only took 15-20 spanks before she had me howling, kicking, begging & promising her anything if she'd just let me up. I tried getting up, but she just laughed & held me down tighter, saying "you're not going anywhere until I say you are", & spanked on. She had me crying long before 51. She turned to my wife & asked her what other family traditions we have. My wife said she flips me over after my spanking & has me nurse on her breasts as she strokes me to sooth me. So my mil took her top & bra off & told me to suck. So I sucked, as she stroked. My mil asked what else? My wife told her my nipples are just as sensitive as hers & sucked on & bites them, before blowing my candle out. My mil, lied me flat on my back, across her lap, & told my wife to take care of my nipples, so she did. Then I felt a warm wet mouth sucking me for all she was worth. I was getting close to losing control, when my wife laughed, French kissed me (her tongue went all the way down my throat), before returning to my nipples & bit hard, which sent me over the edge, as my mil came off of me & finished me off with her hand. She wanted to see me shoot into the air. Now I get spanked by both, & they have their way with me afterward.
