It goes well, until an interruption

Ursula sits back against the pillows, legs spread wide to reveal the pussy you have come to know so well recently. "Come boy-king. You've earned it." She rubs herself as you collect your thoughts. Ok, this is it. You focus all of your self-control on not finishing too early. Between the ferocity of your arousal and the delayment of your gratification, it's a credible danger. You crawl over to where she lays, her beautiful body matronly yet young at the same time. You ready your cock at her entrance, while you grope a plump breast with the other. She laughs a low, sensual laugh. "They always love the breasts" she says, more to herself. You smile briefly, but get back to the task at hand. Your erection is throbbing, begging to be put in her. You slowly breach her outer lips and begins sliding into her folds. It goes in easy, as she is amply wet. You start breathing harder immediately, trying not to lose control on the first thrust. Ursula moans and closes her eyes. "Mmm, it's been so long since I've had a nice big one. I hope you know how to use it." You don't answer, too focused on your self-discipline. Her inner walls grip you with soft warmth as you slide in and out slowly. You've closed your eyes to help maintain focus, but Ursula strokes your face gently to get your attention. You open your eyes to find a huge perky breast held up in your face. "Suck on it like you're my little baby" Ursula commands in a soft voice. You open your mouth and take her hard nipple in a directed, licking back and forth with the tip of your tingue. Ursula sighs in pleasure as you continue to suck and fuck her. Even though your balls ache for release, the overall experience is so pleasant you'd draw it out regardless. You feel like you could go on like this forever.

That is, until you hear the door opening. The rattle of a key in the lock is your only warning, causing your blood to turn to ice. You turn your head, still half inside Ursula's depths, prepared to see Maven. If you weren't so shocked you were be relieved to see it is only a teary-eyed Eufemia. "Mooooomyyyyy!" she wails plaintively, tears in her eyes. "Go away Eufemia, adults only!" Ursula snaps at her acidly. You've become paralyzed with shock, dick still in the girl's mother. Eufemia runs over pouting. "You always take all the pretty boys! It's not fair it's not fair!" She begins to weakly smack at her mother with her little fists, as if you weren't even there. Ursula seizes one of her wrists viciously. "If you want them, learn to seduce them. Don't blame me for your faults!" She easily flings her daughter to the ground from the wrist. Eufemia is barely holding back her tears now. "You only get them because you have big saggy tits!" Ursula bares her teeth, looking genuinely offended. "Big and saggy are they? We'll, they're plenty good enough to get what I want. Just watch!" Having said this, she seems to remember that you're there (and so do you). Ursula wraps her arms around your neck, pulling your face into her ample cleavage. As your face becomes surrounded by soft, sweaty breast flesh, Ursula wraps her legs around your waist and begins grinding against you with a wild abandon you didn't expect from the normally placid temptress. Between the stimulation of the lusty succubus' body and the wild turn of events breaking your concentration, you almost don't even realize it as she milks a climax from you. A wave of unexpectedly powerful pleasure shoots through your whole form as you scream a muffled, primal yell into Ursula's tits. Your cock is lain up against her cervix as one of the most powerful orgasms of your life causes you to shoot massive blasts of baby-maker into Ursula.

Ursula continues to cling to you possessively, grinding a little more out of you whenever you think you've finally finished. Eufemia sits on the ground, head held in her hands as she weeps from jealousy. "Learn...your place...child" Ursula tells her between deep sighs of exhaustion.
