Winter finishes him off on top of Katie

“You’ve been busy,” she laughed.

It was a pleasant reaction, knowing she wasn’t cross because he left her alone in the lounge room to fuck her sister. She came in and rubbed his back, forcing him to take off the T-shirt that he left on while fucking Katie.

“Trust me, she initiated this, leading me in here,” he replied.

“You just can’t say no to to a girl with nice titties can you?” she said, holding his chin while she leaned in to kiss him.

He kissed her back, having another passionate make out session. Eventually her hand travelled to his cock where she started stroking the wet and sticky hard member.

“You’re ready to cum, aren’t you?” She said, sensing it just from the little bit of touching she was doing.

Mark nodded his head, **** to let out a second load for the night.

“You’ve got two big tits right there that you can finish yourself on,” she said, pointing to her sister’s naked body in front of him.

He felt a little weird about it considering she was now passed out asleep on him. But it was Winter’s idea and she wanted to push him into doing it, knowing he couldn’t stop staring at Katie’s bare breasts.

“Move up here,” she said, still holding his cock while walking up the side of the bed.

She had directed him far enough that he was now hovering above her stomach. Katie’s warm body felt great brushing against his butt.

Winter locked eyes on Mark as she started jerking him off quickly.

It wasn’t going to take long at all, he couldn’t decide whether to look into Winter’s eyes or Katie’s exposed breasts. So he decided to go back and fourth as his dick was jerked.

Her hand fired away, running the length of his shaft. She was more than familiar with his cock by now and the way she wanked it was the ultimate proof.

“mmm shit,” he mumbled, feeling it rising.

Mark edged the tiniest bit further towards Katie’s naked breasts.

“Cum on her,” Winter whispered to her, “Cum on her boobs.”

He didn’t need any more encouragement, Mark felt his orgasm rising and so did Winter who jerked even faster knowing he was about to explode.

“Urggnhhh,” Mark let out as he started spurting cum all over her. Winter tried to hold it in place, making sure the drops would end up on her sister’s gigantic tits and not on the bed sheet covers besides her.

“Fucking hell, fuck that was good,” he said as Winter let go off his cock.

“Come on babe, let’s find a spare bed, I’m so tired,” she said, slapping his naked butt.

Mark shuffled off the bed, leaving Katie naked with cum stains all over her sleeping breasts.

He didn’t know how to feel about everything that had happened tonight. Mark wondered if he and Winter really would get together eventually and how the fact that he had fucked Katie twice now, affect that.

What he knew for sure was, if he was ever to marry Winter, their family gatherings would sure be interesting.
