"I am sorry"

I blurt out, looking down at my step-mom covered in my cum.

Millie looks up at me, still in shock, then she starts to laugh loudly. I feel confused, not knowing what to do or say, so I start laughing too. After a few seconds of this, Millie says:

"Get me a towel, will you?"

I take one from underneath the table between us and hand it to her, and she uses it to clean up my cum from her breasts, neck, and face. When she's finished, she hands me back the towel, then says:

"Quite an impressive load you blew there, young man."

"Thank you." I reply, not knowing what to say.

Millie leans back on her sun lounger, closing her eyes, and saying:

"Guess you are into big tits like your dad, huh?"

I laugh and reply:

"Yup, sure am."

We sit there in silence for a while, then Millie says:

"I guess you'll be okay with me going topless for a while."

Then, without waiting for me to reply, she sits up, reaches behind her and unties her bikini. As they are freed from the confines of the bikini, my step-mom's breasts drop a little, but not very much.

Millie lays back down, her nipples pointing up in the air. I feel a twinge in my cock as I am watching her naked big tits, then Millie turns her head towards me, just looking at me for a little while, then says:

"Matt, it makes me feel really good about myself that I turn you on like this."

I smile at my step-mom and say:

"You are a very beautiful woman Millie."

"Thank you Matt." Millie says, keeping eye contact for another second, then leaning back on her sun lounger again.

I lay there looking at my step-mom's big tits for a while, then I too close my eyes and doze in the sun.
