I actually fell asleep, and was jolted out of that by my sister’s sharp fingernail in my ribs.“Get up. Come to my room,” she whispered.I stumble... after her, a little groggy. She was still dressed in the outfit I hadn’t chosen for her. It was more conservative than the one she’d worn to feel sexy in with Dennis. It was what I’d call a summer dress, with two inch wide straps over the shoulders and no cleavage at all. It was flowered. She had on sandals.“How do I look?” she asked, once her door. I was sucking her right boobs while i was playing with her left nipple with my fingers. I was pinching it and pressing it. Her boobs were becoming hornier by the time i was pinching it. So i started to suck it harder. She was giving heavy moans. As it was a big house, no one outside could hear the sound which we are giving. then she got up and said i want to have your cock on my mouth. I readily accepted for that since i was a bit tired after a long journey from top to bottom. I was lying down. She pulled back coughing slightly to take my second and third in her mouth. Then, as I looked down at her, she looked up at me and literally sucked my final discharge from my cock. I saw her swallow before letting her tongue bathe my sensitive engorged cock, taking away the final traces of my sperm.Still holding my cock in her soft hands, Heather moved back to sit alongside me on the couch. Our lips touched in a kiss, then our tongues moved to find the other, enabling me to taste the heady. They had used it for their pleasure on more than one occasion. It they were not already dressed, they would have shared the shower with him. Tricia picked up his sweaty jock-strap off the carpet and swung it under her friend's nostrils because she knew how kinky Trudy was about getting her brother's scent at special times. Trudy's kinkiness was exciting to Tricia and she loved to tantalize her just to see her reactions.Trudy was holding the sodden jock-strap in both of her hands and Tricia.
