Kasumi lay there panting, chest heaving, face still shiny with her sister's squirt and a dazed, satisfied smile on her lips.
"Oh my God… that was so intense…"
Tomiko, still on her hands and knees with my cum slowly leaking from her stretched asshole, reached over without warning and gave Kasumi's swollen, sensitive clit a sharp little slap.
Smack.
Kasumi yelped, thighs jerking.
"I didn't expect my elder sister to be so naughty…" Tomiko teased, voice still husky.
Kasumi's eyes flashed. She didn't back down for a second. Her hand cracked hard across Tomiko's soft, cum-streaked ass.
SMACK!
The sharp sound echoed in the quiet living room. Tomiko hissed through her teeth, but the corners of her mouth curled up in a wicked little grin.
I chuckled, low and tired but still very much interested. My cock was already thickening again just from watching the two sisters bicker and slap each other.
"Alright… enough for the living room."
