The few moments that Amy takes him into her mouth, he lets out a pleasured groan. When she gets up to move, he rises with her. On the way back to his room  he turns and deeply kisses her, like as if it was still a "secret thing" in the family. He slides his fingers into her pussy as they walk, given she has a hold of her shaft. His fingers even had nice time sliding into her wet pussy. He could feel how tight she was. When they got to his room, he laid his closest sister on the bed, laying on top of her nude sexy form and kissing her deeply once me, rubbing the underside of his shaft on her pussy as the sensations escalate.
