I dutifully complied. What does Sis have in mind for me now I thought! I went out to the porch and bowed before my sister/mistress who lay topless on ... lounge chair! Her small firm round breasts glistened in the sunlight! She was rubbing suntan oil all over hot body! Her brown puffy nipples grew stiff as she smiled at the growing bulge in my pants! She had me kneel before her & kiss her feet good morning! She sat up and spread her legs! She had on a pair of tight white panties she had from her. Jack would not have stirred the teen's interest either, because she was really not much interested in the out-of-doors except that one day when the dog came visiting he spent a good deal of time licking his bright red prick which kept pulsating in and out of the sheath beneath the dog's belly. The sight of the animal licking itself might have in any other situation either embarrassed Tara or caused her to say, 'Oh gross!' but just that day she had received a letter from her apparently. As he sat down he spread his legs apart and I quickly moved in between them and taking hold of his cock again, began to suck on it in earnest. For several minutes I sucked and licked his cock with a feverish delight, enjoying the taste and the firmness in my mouth as he occasionally slapped at my face. When he had enough, he grabbed hold of my hair and pulled me off to one side and got up off the sofa, "Get on your back whore" he ordered me and I laid down on the floor. He finished taking off. I lost track of him last night."Richard sighed."Tammie?" He affixed the girl with a glare."I'm ... not sure Uncle Rich. I don't really remember getting back to the room last night. I'm not sure what happened." She looked scared.Richard exchanged a look with Perry.His brother-in-law nodded. They'd need to keep an eye on the drinking as the kids approached college-age.How ironic. Worrying about drinking when your kids are boinking each other daily. Snort.Suki walked up. She pulled Richard.
