In the dress

"Well, if that is the case, then..." you turn her around, push her chest down so that her hands fall on the bench, and hike her dress over her ass. Your eyes fall to the black throng that is in the pile of clothes on the floor. "You naughty milf. You didn't wear underwear while trying on this dress."

"I'm a mother you would like to fuck, now am I? " she laughs

"I thought that was understood" you slowly guide your dick into her pink pussy lips. Your old dick size would have easily slid inside her "experienced" vagina, but due to your increase in size, it is an extremely tight squeeze causing her to let out a moan. "I'm bigger than your husband," you slap her big tone ass

"Mu muh oh yeees very much so, but it feels so good," you hear a voice from behind you as you feel the breeze of the door open.

"Mom, what's taking..." He turns his head to see Samantha standing there, speechless. She is clearly about ready to scream out.
