I look to Megan, afraid that she'll be angry after Sam's comment about groping her boobs, "I..."
Meg interrupts my attempt at an explanation, "Don't worry about it, I would have copped a feel too, she has nice tits." As she says this she reaches a hand up and gives her sister's little tit a nice squeeze.
"Want to feel them again?" Sam grins at me. I look at Megan again and she nods her consent.
I can't turn down an opportunity like this so I reach out my hand slowly cup Sam's other tit. As the palm of my hand presses into her warm hard nipple Sam let's out a low moan. I cup her small boob in the palm of my hand and slowly run my thumb over the smooth skin of her breast. I circle and slowly approach her nipple. When my thumb gets to her nipple I play with the little nub and bring over another finger and give it a slight pinch.
"Oh! Dan..." Sam's breathing has noticably increased and chest had become slightly flushed.
Just then Megan clears her throat.
