[Reducing Mosaic]HUNTB-533 "Even though it's small, you can still squeeze a dick in it!" The little sister who was made fun of for having small tits desperately tries to give a blowjob with her breasts... but it turns into a handjob instead! But the handjob feels so good

My sister, who has small breasts, mocked me for liking big breasts. She desperately tried to give me a blowjob as revenge, but it turned into penis penetration instead. However, the penis penetration felt so good that I was about to cum... Even though I didn't want to admit it was a blowjob, my sister was secretly enjoying it too, and we both reached our limits and simultaneously climaxed! Worse yet, in her post-orgasm state of arousal, my sister said 'more' and became increasingly lewd. Honestly, I hadn't been interested in women other than those with big breasts before, but this incident made me re-evaluate small-breasted girls!
