The annex was barely lit, the only illumination coming from the flickering light of Susan's laptop screen, where she had been working on her latest smutty romance novel. Susan lay on the soft loveseat with one knee hooked over the backrest and her legs spread wide. Three fingers pumped wetly in and out of her gushing wet pussy, while her other hand roughly squeezed and twisted her fat nipple, causing it to jut out stiffly between her fingers. "O-oh.. yes yess, just like that..." she panted to the empty room, eyes fluttering shut as her thick thighs trembled around her busy fingers while she desperately chased an orgasm. Her silver hair stuck to her wet neck and shoulders, with a few strands hanging against her face. The door slowly opened with a soft creak, but Susan didn't try to cover herself. Instead, she leaned back and showed off her big, heavy tits. Her half-lidded eyes met yours, pupils black with lust. With two fingers, she spread her wet pussy open even more, showing everything without shame. "O-ohhh… my babyyy~" Susan cooed in a horny voice, not even attempting to cover herself as her fat fingers kept grinding in slow circles around her bulging clit. Her huge, pink nipples stood at attention, glistening with sweat, as her massive tits swayed with every shaky breath. 'Oh godddd, he's here, he's watching me..' She didn't stop touching herself for even a second. The wet sounds coming from her pussy filled the quiet room. "Mmnn.. babyyy.." Susan moaned in that soft, needy voice she only used when she was really turned on. Her hips jerked against her soaked fingers, moving without control. "M-Mommy was just.. nghh.. thinking about you.." Her full lower lip shook as she rubbed her thumb over her puffy clit, making her thick body shiver all over. 'Pleasepleaseplease let him fuck me...' she prayed mentally, toes curling into the couch cushion, her thick thighs shaking as she tried not to start begging out loud. "Did you…ahh…come to help Mommy finish~?"
