Your Step-mom wants you get your step-aunt “fertilized”

You’re in the living room when the front door opens. Marsha walks in with her usual no-nonsense expression, followed closely by her younger sister Sofia, who’s wearing an oversized white sweater with a cartoon cat and the words “PLS LOVE ME” across the chest. Marsha plants her hands on her hips and looks straight at you.

“We need to talk.” Sofia stands slightly behind her, one hand lifting the hem of her sweater just enough to show a bit of soft stomach, cheeks faintly pink but eyes hopeful. “Your aunt wants a baby,” Marsha continues flatly. “She’s been talking about it for months. She can’t find anyone reliable, and I’m not letting her go to some stranger. You’re the only donor that makes sense. It would be rude to say no.”

Sofia peeks around her sister’s shoulder, voice soft but clear. “...I’ve always wanted a baby that looks like family. You’re the only one who can give me that.” Marsha crosses her arms, tone leaving no room for argument.

“Good, natural insemination may take a while at her age, but I expect you to do your part no matter how long it takes. She’s staying here until it happens. So get used to the idea.” Sofia gives you a small, shy smile from behind her sister, clearly already on board with the plan.

You wake up to the soft, wet heat of a mouth wrapped around your cock. Sofia is under the blanket, her messy auburn hair spilling across your thighs as she slowly bobs her head. Her soft, plush lips slide up and down your length with lazy but eager attention, tongue dragging along the underside. She makes small, contented sounds as she works, clearly having been at it for a little while already.

When she feels you stir, she pulls off with a soft, wet pop and looks up at you from between your legs. Her cheeks are flushed, eyes a little glassy, and there’s a thin string of saliva still connecting her lower lip to your tip. “...Good morning,” she whispers, voice a bit hoarse. “I didn’t want to wait until later.”

She gives the head of your cock another slow lick, then rests her cheek against your thigh, still holding you in one soft hand. “I’ve been thinking about it all night. About actually trying for real. About having a baby that looks like family.” Her thumb strokes along your shaft absently.

“Linda said I should be proactive... so I figured waking you up like this was a good start.” Sofia shifts, climbing up your body until she’s straddling your hips, her soft stomach and full breasts pressing against you as she looks down at you with quiet hope.

“Are you up for it right now?” she asks softly. “I want to try again. Properly. I want you to finish inside me... for my baby.” She reaches down and guides you against her already-wet entrance, waiting for your answer with a shy but determined expression.

It’s late. The living room is lit only by the soft glow of the TV that neither of you is watching. Sofia is on her back on the couch, oversized sweater pushed up under her chin, soft thighs spread wide around your hips as you thrust into her. Her messy auburn hair is fanned across the cushion, and every roll of your hips draws a breathy, addicted little moan from her lips.

“Nngh... right there— don’t stop...” she whimpers, arms wrapped around your shoulders. “I’ve been thinking about this all day... You’re going to get me pregnant eventually if we keep going like this... I don’t even care how long it takes anymore...”

She’s completely lost in it, heels digging into the backs of your thighs, soft body moving with yours in a steady, desperate rhythm. Then the hallway light flicks on. Marsha steps into the living room in her robe, arms already crossed, expression flat with disapproval.

“For God’s sake.” Sofia freezes mid-moan, eyes wide, still impaled on you. Marsha doesn’t even look shocked — just tired and annoyed. “You’ve been at it every single night for two weeks. The guest room exists. His room exists. The couch is not a breeding station.” She pinches the bridge of her nose.

“I can hear you from upstairs. The neighbors can probably hear you.” Sofia sinks lower into the cushions, still breathing hard, cheeks burning. “...We were just—”

“I know exactly what you were doing,” Marsha cuts her off. “And I’m not stopping you. You’re supposed to be trying. But at least take it behind a door like normal people.” She points down the hall. “Go to the guest room. And keep it down. Some of us still have work in the morning.”

Marsha turns to leave, then pauses in the doorway without looking back. “And Sofia — stop getting so loud. You’re not the only one living here.” The hallway light stays on as she walks away, leaving the two of you still tangled on the couch.
