Clark is back and starts to learn new things

Clark groaned in discomfort as he left the bathroom. He tried is best to get rid of his troublesome's erection, clearly visible through his pants. He spent fifteen minutes jacking off, first fantasying about dark-haired vixen clearly one of the sexiest women he ever saw. The thought of her on her knees sucking his cock was enough to bring him toward climax. But despite this, it wasn't enough and his dick remained harder than steel, looking even bigger than before. Gradually his fantasy became lewder and more depraved as he pictured Tracy and his teacher alternating between fucking and sucking him, the ebony-skinned woman looking younger and sexier than ever. He never had any fantasies about her but here, it was enough to give him two more climaxes. Still, his cock didn't go down, much to his dismay. Coming back into the living room, he hoped no one will notice the embarrassing bulge and he could leave early.

Ant this was how he ended up in Barbara's living room, staring silently, mouth agape at the lewd show taking place in front of him. His teacher was still sitting on the couch, her bare breasts on display. Tracy was on her knees on Barbara's side, one hand massaging her friend's chest while the other was slowly caressing her belly, just below her mons. The dark-haired vixen moaned softly as Barbara kept sucking her nipple, drawing more milk from her seemingly inexhaustible mammaries. Noticing his entrance, Tracy put a finger to her mouth, asking him to remain silent, before motioning to him with the same curled finger. Clark moved silently toward the duo, staring at the gorgeous seductress in wonder. She continued to caress Barbara's heavy breast with one hand while the other dipped below the waistband of her pants and began to tease Barbara's panties covered crotch.

"Come here," she whispered, not wanting to alert Barbara who still had her eyes closed, fully focused on the combined sensations of Tracy's hands, her sweet tainted milk and the slow transformation of her body. The teenager gingerly stepped towards them, his eyes fixated on her teacher's breasts. Did she always look this good? Her breasts must be at least E cups if not bigger, and they looked so firm and perky and her face looked 10 years old younger. He kneeled in front of Tracy, not resisting as she pulled the mesmerized teen's head down to her other tit. Instinctively, his lips fastened around the fleshy nub, sucking hard to get at her tasty fluid. Tracy cooed lustfully as both of her breasts were being worshipped. Removing her hand from his head, she brought it on the massive bulge between his legs, deftly extracting his 9 inches boner from his pants. As she began to caress his length with nimble fingers, Clark grew bolder, wrapping his hands around Tracy's heavy glove, squeezing more milk into his hungry mouth.

Clark's presence next to her was finally enough to put Barbara out of her trance. Opening her hazy eyes, she was shocked at the sight in front of her. She realized she had been tricked into lesbian sex with her friend, while her student was also involved in this debauched actions. She was about to yell at them but her sight was caught by the actions occurring in front of her. She stared at his student, the strapping young man drinking Tracy's milk, the succulent fluid's taste still lingering on her tongue, her arousal growing at the sight of Tracy's magnificent bosom. Lowering her gaze, she watched Clark's large cock, clear fluid slowly dripping from the tip as Tracy kept masturbating him. Words died in her throat as her lust rose again.

"Ooooohh... yesss " Tracy hissed, "You learn fast. You're definitely better with your tongue than in arithmetics" she said, an impish smile on her face as her eyes locked into Barbara's.

"I think he's a quick learner my dear, do you want to help me teaching him new things? I'm sure you'll be a good teacher for him."

With this lewd invitation, she removed her hand from Clark's shaft, a copious amount of pre-cum slathering her digits as she brought them in front of Barbara's mesmerized face.

"Want a taste?"
