Everybody comes together

From Torg Adventure

Jimmy heard them kissing again, but Tammy was really riding him hard. He was getting close to cumming, but was holding out for at least one of the other two to go first. He redoubled his tongue work on his sister's pussy. He thought he needed an edge, so he got a finger wet on her slipperiness and poked it inside her. He got a very satisfying moan from her. Then he delved for her G-spot, probing with his finger in quick short strokes. Her G-spot was a large lump and very sensitive, judging by the volume of her outbursts. Adding another finger, Jenny's groans got louder and higher pitched.
