They spank you...

Eventually Lisas ass is a nice pinkish/reddish tone and Tanya seems satisfied.
"There there girl, now you´ve learned your lesson."
"Yes Mam."

Tanya looked over to you. "Now for your naughty boyfriend."
"Ehm, I´m not really into..." You start, but Tanya just slams her hand over your mouth and pulls you by the arms to bend you over her lap. She even positions you so that your dick is squeezed between her lovely thighs. Then she starts to spank you like she spanked Lisa. Smacking hard, then kneading the cheek like dough and then repeat.

She even brings in Lisa, showing her how much **** and how to hold the hand as you smack an ass, completely ignoring your yelps...
