Dean and Scott were neighbors and although Dean was 14 and Scott was 15, they got along well. Shortly after the school year ended in 1974 the boys were in the basement of Dean's house playing Monopoly. They had been playing for some time when a friendly disagreement broke out. After some talk Scott said sarcastically, “Oh suck my dick!” Dean looked right at him and said, “You take it out and I will!” Scott immediately stood, unzipped his jeans and pulled out his penis. Dean stepped forward and to Scott’s surprise began sucking on his penis. As he felt his penis harden in the other boy’s mouth, he closed his eyes enjoying the sensation of a warm mouth sucking him. Without stopping his sucking, Dean unfastened Scott's jeans and pulled them to the floor. He continued to suck Scott for a few minutes, and when he stopped, he looked up at Scott and said, “This is great! The kid who used to live next door and I did this all the time!” He went back to sucking Scott’s penis. When Dean stopped, he said, “If you don’t want to suck me, it’s okay, but I’d like to do this whenever we can be alone.” Scott thought for a moment and said, “Let me think for a moment. Okay let's move to the crawl space under the stairs, we can continue there. "
Dean was excited with this thought. The boys moved to the space, Scott unzipped Dean's pants and started stroking his member. Mesmerized by it growing in his hand. He moved closer to examine the head. Dean moans softly. Unknown to either of the boys, Dean's older sister, Sherry, came down stairs.  Quietly she moves around the stairs to the crawl space opening, where she sees the two boys, Scott with his pants down around his ankles, stroking her brother’s cock.  A low gasp escapes her lips. The two boys hear her and are surprised. Sherry says “don’t stop, or I'll tell mom and dad." Scott reluntly continues stroking Dean's cock, slowly he approaches and puts the swollen member in his mouth, and begins sucking bobbing his head up and down. Sherry watches intently then says “Dean, remove your pants so I can get a better look.” Dean unbuckled his pants letting them drop, Scott pulls down his underwear to expose Dean's entire member, and with one hand Scott reaches up and massages Dean's nut sack. Sherry can’t believe what she’s sees. Her younger brother being sucked off by her neighbor. Unknowing she reaches for her own crotch and begins to rub herself.
Scott flicks his tongue under the head of the penis, causing dean to push Scott's head all the way down his shaft.
Scott felling Dean's nuts begin to to swell up, stops long enough, " I have something to try, let's move back to that old mattress back there , it will be easier on my knee's " they all move back farther into the crawl space, removing all their cloths. " Dean , lay down"
Dean lays naked in the mattress, then Scott does the unexpected. Sherry watches in awe as Scott lowers himself on Dean's 6" curumsied dick.  Slowly Scott begins to move on Dean's hardened cock. Sherry continues to rub her crotch, with her other hand she reaches under her tank top, to massage her 38D boobs.  She watches intently as Scott's 8" uncircumcised cock bobs as he fucks himself on her brother dick.  She’s has only seen her brothers when they were younger taking baths together.
Sherry moves closer, then grabs Scott's cock and jerks it to the rhythm of his bouncing.  Dean lets out a moan as he watches his sister jerk his friend.  Scott unable to contain himself, pulls up sherry's tank top exposing her bubble gum coloured, harden nipples, he grabs both and pulls on them, causing sherry to squeal in delight.  She stokes Scott faster, as he grinds on Dean's member.  Scott cums all over sherry's hand. Dean seeing this, is too much for him, as he unloads his hot cum in Scott’s ass. Sherry scoops up the cum and feeds it back to Scott, she says " you should cum over more often, we can play more games together, how’s doctor sound to you both?" Scott says “great, I think you need a full examination “holding up sherries cum drenched hand. Reaching for her other hand and licking it, “it seems to me, you’re a little leaky down there"  taking the opportunity to reach into her daisy Duke shorts,  down past the soft mound of  now moist public hair, and slowly inserts 2 fingers in sherry’s pussy.  She closes her eyes lost in the feeling, Scott rubs her swollen clit, gathering her wetness in the 2 cupped fingers.   Removing them slowly he brings them to her face to see the clear gooey film like liquid, before Scott licks it all off.  Dean watches this and takes the opportunity to reach around and squeeze his sister’s tit, this made his cock hard again and began pumping into Scott’s ass. Scott taking the que grabbed the other one and pinched it. While grinding down on Dean’s Harding cock in his ass. Sherry breaks free from their grip, pulls up her top and presses Scott’s face between her full ample tits and shakes them, this time Dean grabs Scott’s cock and strokes him as he pumps himself deep in his ass, sherry reaches down and plays with his balls  massaging both Scott’s and her brother’s .  Sherry stands up and slips her hot pants down, and hovers over scotts face, “here, get a closer look” as she puts her now dripping pussy over his face.  Scott Crain’s his neck to burry his face in her slit lapping up the leaking liquid.  Sherry’s knees buckle under the probing tongue.  In one quick movement she lands herself on Scotts cock, grinding her hips to her brother’s assault on Scott’s ass. The sudden movement cause Dean to gab his sister’s waist as Scott massages her massive tits pulling on her nipples.   Dean manages to rasp,” that’s it sherry, fuck us both “sherry obviously hearing this begins to buck wildly on the two boys.  Dean releases his second load into Scott’s ass still dripping from the first one, Scott unable to contain himself anymore says he’s about to cum sherry jumps off and Jerks Scott to completion, spraying into her face.   Cum covered, she approaches his face where they kiss, and says “now that’s what I call an examination!”
