Registered Massage

When I was 18 my older sister (21) was going through her Registered Massage Therapist (RMT) studies. She often used us family members as practice dummies which for us, was great. I’m very well endowed, 8 inches long but really thick at a 7 inch girth. My sister on one occasion had a fellow student, whom I will call Susan, come to our home for a practice session since she was absent family of her own to practice on. Susan was very pretty with a hotter than hot body. I was completely nude of course under the sheet but at one point while face down got an erection that poked out between my legs. As Susan was massaging my hamstrings her hand made contact with my erection. She was puzzled and lifted the sheet to see what the object was and made an audible sound when she saw that it was my hammer. She screamed “Oh my God!” My sister looked and laughed adding, “He gets that from our father.” I apologized and after some time it calmed down. Then she had me roll over. All I had to do was see her fucking body and bang, up it came again. They both had a big laugh. My sister quickly pulled the sheet from my body exposing me fully nude on the table. Her friend Susan put her hand around it, or tried saying,”I can’t put my hand all the way around it!” She didn’t let go and in fact her already lubed hands began working it. I laid back just enjoying the attention but after about five minutes she tried to put her mouth around it but failed. They were both laughing. She said she had to have it in her, took off her spandex and got over top of me, rubbing her pussy up and down my cock but not putting me in. My sister joined in by lubing up my dick as to make it easier on her friend. She then held my cock helping guide it into Susan’s pussy. She ever so slowly sank herself down my cock finally to its base. It felt fucking great of course. She took her top off and I played with her tits. She made comment on how my girth was pulling on her clit on each downward thrust. Each time she thrusted down she shuddered, breathing heavy and after but minutes went to full orgasm. I unfortunately didn’t cum. She got off the table collapsing onto the couch telling my sister how fucking great it was. “Oh my God my clit has never been rubbed like that!” My sister said her pussy was soaked watching us with her friend saying “fuck him!” My sister looked at me and then dropped her laundry straddled my hard on and sank it with a lot of trouble. She’s a small woman and although she took it all she wasn’t enjoying it as much as her friend and dismounted. I grabbed her ass in my hands and pulled her over my face. She said, “No you’re my brother!” But she really didn’t put up a fight. I licked and sucked her pussy to orgasm. I got off the table and her friend lay down on it. Susan spread her legs and I slowly sunk myself in her. She again could not believe how my dick pulled her clit into her hole. She came pretty quickly but I kept pounding until I came. Well word got around her class and it would seem she had a group who were wanting me as a practice dummy. She refused their wants but her friend Susan and I fucked me for months. Good times.
