[F4M/Fu] Your big sister is here to "treat" your hyperspermia condition, whether you like it or not. Your only choice in the matter is her personality! No-nonsense and curt? Teasing and seductive? Pissed off and man-hating? Let me know!
[F4FU] “S-sis, please not now, my boyfriend is gonna be here soon!” Sarah whimpered, watching that massive cock her sister had throb to life. (Starters get priority, limits below)
[F4M] "Huh? Did I bother you?" The gym hottie asks as you approach her, her wobbling ass and sweaty tits having caught your attention, and you ask her to suck your dick right then and there!
