You wife’s sister in having another family get together, and you still can’t help but admire her breasts. Not that she purposely is flirtatious or even interested in you nor aware of the attraction you have towards her. Just a little secret crush and curiosity of your sister-in-law’s perfect seemingly all natural breasts, she always has cleavage showing and you’re honestly looking forward to sneaking a few peeks at the party. She’s oblivious to your stares down her shirt as she bends forward and you can’t take your eyes away while she takes a turn on the trampoline, hoping your wife nor anyone else noticed your stares, or when she spills her beverages on herself… you can’t help yourself, you follow sneaking behind her to her bedroom and to your amazement she’s left the door open enough for you to watch her undress. You do your best not to get caught, but when she spills on herself a second time after fixing her bra strap right in front of you you can’t help your urges and again follow her in hopes to watch her change again… and when she invites you in and takes your hand and places it directly on her breast you consumed by arousal, barely noticing she obviously thought you were her husband, and before you know it words are spilling from your mouth, “If you don’t let me feel them again I’ll tell your husband you came onto me.” She laughs at you, rolls her eyes grabs your hand and lets you grope her breasts for awhile until making you stop and leave, shutting the door behind you. Your amazed and in shock, did that just happen?
