My reserved sister in law wants to lose her virginity and gets penetrated by me, resulting in ejaculation on her buttocks

My shy sis-in-law visits, eager to lose her virginity. I guide her through undressing, teasing her nipples and pussy. I penetrate her, she squirts, and I ejaculate on her buttocks.

My reserved sister in law has been yearning for a passionate encounter, and I've been eager to fulfill her desires. Unbeknownst to my wife, I've been indulging in steamy sessions with her, exploring every inch of her luscious curves. As I've been working from home, the opportunity to explore our forbidden fantasies has been irresistible. Recently, she hinted at wanting to take our relationship to the next level. With a seductive smile, I teased her pink pussy, sending waves of pleasure coursing through her body. As she surrendered to ecstasy, her tight pussy erupted in a powerful orgasm. I continued my relentless assault, delving deeper into her depths until I reached the gates of her virginity. With a final thrust, I breached her untouched territory, eliciting a delicious moan from her. As I reached my climax, I released my hot load onto her firm buttocks, marking the culmination of our intimate encounter.
