The foursome begins

From Torg Adventure

As you watch, Kelly and Kris pull their shirts off, revealing their bare breasts. You take your shirt off and Kris runs a hand on your pecs and teases your nipples. Stacey scoots her panties off and helps Kelly take hers off.

Your nieces sit on the couch naked, Stacey in the middle, looking at you with lustful eyes. Your cock points at them, quivering in anticipation. Kris strokes her pussy lips. Stacey squeezes her breasts, and Kelly fingers herself.
