Mom's cries echo through the room as you continue to spank her, her body arching off the bed in a futile attempt to escape your punishing grip. The sight of Luna and Emily watching, their faces flushed and eyes bright with desire, only serves to intensify the shame she feels but also adds another layer of pleasure beneath the pain.

As you continue to spank her, Mom can feel the wetness between her legs growing more insistent. The thought of Luna and Emily watching only serves to heighten her arousal, making her moan even louder with each impact. "Please," she begs, "don't stop..." Her voice is hoarse from the combined effects of pain and pleasure, but there's a newfound desperation in it now as well.

Emily bites her lip, thinking for a moment. "Um... maybe we should start with just touching and stuff? I've never done anything like this before..." she says quietly, blushing even harder as she looks between you both.

Emily nervously reaches out, touching your erection tentatively. She lets out a soft gasp as she feels how hard you are and slowly begins to stroke you, her fingers shaking slightly. Looking over at James, she watches as he positions himself behind you and starts to thrust gently into your ass.

James moans softly, his body tensing with pleasure as he fucks you. He looks down at Emily, wanting to tell her how good it feels but unable to find the words.

Mary giggles again, a blush spreading across her cheeks. "Oh, well..." she starts, taking a moment to choose her words carefully. "You see, sometimes grown-ups like to do special things together that aren't appropriate for little ones like you." She glances over at Luna and Bylie, who are still quite preoccupied with each other.

"But that doesn't mean you can't learn about it when you're older," she continues with a wink. "

Luna rolls her eyes, but doesn't say anything as she rides out the last few thrusts with Bylie. Embarrassment still colors her cheeks, but there's an undeniable glow of pleasure as well. She reluctantly dismounts and pulls on a nearby shirt to cover herself up again, shooting glances at their mother and siblings throughout the room.

Luna's fingers dance across your chest, her touch both soft and demanding. Her breath comes in short gasps as she looks up at you with hooded eyes, her lips parted ever so slightly. The lingerie hugs her curves perfectly, emphasizing the desire that burns within her. She needs more... she wants more... but is too afraid to take it.

Luna gasps at your moan, her body responding instinctively to the sound of your desire. She steps closer still, her hips brushing against yours as she leans in to whisper in your ear. "What do you want, little brother?" Her voice trembles with need and uncertainty, betraying her true feelings.

Her breasts graze your chest as she moves, the lace of her bra tickling your sensitive skin. She's so close now... just a few more inches...

As Mary cleaned Luna's pussy with the napkin, she couldn't help but feel aroused by the intimate contact. Her fingers moved in a rhythmic motion, rubbing circles around her daughter's swollen folds as she moaned softly. The sensation of Luna's wetness against her skin sent shivers down her spine, heightening her desire even further.

"Mom... I'm sorry," Luna repeated, sounding dazed and out of it. "

Mary smiled warmly at Luna and continued to rub her pussy, saying softly, "It's okay, sweetie. We all make mistakes sometimes." Her fingers moved faster against Luna's sensitive skin, eliciting moans of pleasure from the emotionally charged girl. As Mary lost herself in the sensations, she couldn't help but wonder what it would feel like to be touched by her own son...

Luna's cheeks flush even darker at your new demand, but she can't help the small shiver of pleasure that runs through her at the thought. She moans into the kiss, pushing herself harder against you as her hips grind faster. "Daddy..." she whispers, her voice breathy and desperate. Her hands move to grip your shoulders tightly, digging her nails in slightly as she arches her back, offering herself up completely.

Luna lets out a guttural moan, her voice echoing through the room as she loses herself in the pleasure of your kiss. Her hips grind even harder against yours, feeling the need for release building inside her with every passing second. "Oh God... yes..." she pants, her fingernails digging into your shoulders as she holds on tightly.
